Solar Power Water Pump: Can Solar Generator Run A Water Pump
A solar power water pump sounds very exciting indeed. It is the same as a regular water pump except that it has almost zero power consumption cost because it runs on free and renewable energy sources. Using a solar power pump has a lot of advantages, such as it is a green and environment-friendly solution for generating power. It is very cost-effective, and it is portable. Also, it makes you independent of any paid energy resource and is very easy to install.
Solar power water pumps work for irrigation, bird baths, livestock, and off-grid applications. It is interesting to know that there are different solar power water pumps options, such as fully submersible water pumps that can be used for ponds and wells. Then there are the groundwater pumps that may be used for fountains and livestock.
What is Solar Power Water Pump
A solar-powered water pump is a water-pumping machine running on solar energy. As fuel soar, these low-cost energy sources are an alternative to electric and oil-water pumps. It is a great solution for the areas where you need an electricity connection. And even if you have a connection, you may want to try solar power water pumps because of their low cost of running. It gives a viable solution to people in these times of very high fuel costs.
Solar power water pumps have different types.
- The submersible pump is a solar system to draw water from boreholes or deep wells.
- The circulator pump circulates water to keep it warm and ensure a continuous water supply.
- The booster pump moves water from the storage tank to other facility parts.
How Does A Solar Power Water Pump Work
A solar power pump has three main parts, i.e., solar panels, a controller, and a pump. The solar photovoltaic (PV) system’s size depends on the pump’s size, the amount of water to be pumped, and the solar irradiance.
The solar-powered water pump has a very simple working principle based on the photovoltaic concept.
- When sunlight falls on the solar panel’s surface, these panels absorb the solar energy. This absorbed radiant energy is then converted to electricity.
- However, this electricity is in the Direct Current(DC) mode that will not run the AC water pumps. So, here you need a solar pump controller that converts the DC electricity to AC.
- The solar water pumps also use inverters to regulate the voltage output to help the system run smoothly and efficiently.
- The pump uses AC power to draw water and circulates it through the pipes.
- If you want your solar power water pumpto work at night or when you do not get enough sunlight, you also need a generator for your system.
Solar Power Water Pump VS. Solar Generator for Water Pump
You have two choices when using solar energy for your water-pumping system. Either use a solar power water pump or use a solar generator for the water pump. Though you may think there is little difference at face value, there are some nitty gritty details that you need to know.
A solar power water pump is a complete system including a water pump, solar panels, and a controller. On the other hand, a solar generator for a water pump takes your regular AC-powered water pump and powers it up using a separate solar generator. Below diagram shows how a solar generator works.
The following table summarizes the pros and cons of both systems.
Solar power water pump
High cost of purchasing the system.
All the equipment can be used for one system only.
Does not work on cloudy days or low-light weather.
Solar Generator for Water Pump
Your existing water pump will work in this system.
You can use the generator to power up other appliances too.
It would be best to charge your solar generator to work at night.
The water pump and solar generator are independent of each other.
It works even at night or on low-light days with charging.
How Many Running Starting Watts Does A Water Pump Use
When you want to estimate the capacity of your required solar water pump or solar generator, there are two numbers you need to know. One is running watts, and the other is starting watts. So what do they mean?
Running, or rated watts is the continuous supply of watts needed to keep your device running. Starting watts, on the other hand, are extra watts required for two to three seconds to start motor-driven appliances, e.g. a refrigerator or circular saw. This is the maximum wattage a generator can produce.
Running watts: Running watts are also called rated watts. These are the continuous watts needed to keep your solar water pump running.
Starting watts: Starting watts are extra or the highest required watts needed for two to three seconds to start your water pump.

Why We Turned Down an Extra 129 Million Dollars: The Truth about Solar Generators
We’re all familiar with the idea that some things are simply too good to be true.
Unfortunately, there are manufacturers and sellers who prey on our drive for survival in hopes that it overrides our critical thinking skills.
One type of item that’s currently being used to do that are so-called all-in-one power solutions that only require solar energy (aka solar generators).
Solar generators are great—in theory. But, in reality, relying on solar generators for survival is impractical.
For starters, for the solar claims to be valid, you need optimal alignment with the sun for the panels, which could mean having to go outside and continuously adjust your panels every single day.
This isn’t like a solar calculator that can charge in a well-lit room. Your solar generator performance will vary significantly if your panels aren’t properly aligned with each passing hour.
Of course, if your weather features a string or week of cloudy days, you’re out of luck.
Solar generators can also be downright dangerous.
In fact, they’ve been known to cause fires and are so dangerous that one of our competitors had their generator batteries recalled due to fire hazard
There are just so many problems, that My Patriot Supply refuses to sell solar generators to our customers—turning down millions in extra revenue in the process.
Sure, we sell solar-powered devices because they come in handy in certain situations, but we would never recommend relying solely on a solar generator to have all your bases covered during a blackout emergency.
That would be misleading; And honestly, it’s an outright lie.
There are, however, plenty of other companies marketing solar generators as the end-all-be-all survival tool when there is no end-all-be-all.
One of our competitors, for example, has openly advertised how many units they have sold combined with the average selling price to total 129 million in sales.
Before we jump into the specific claims around this product, consider what is happening in the world of solar panels.
North Carolina consumers are currently suing the manufacturing of the roof-based solar panels they were sold. Why? Because they were promised big savings on their energy bills when they actually had to pay a lot of money for solar panels that didn’t work effectively. See the news article here.
And let’s not forget about the multiple high-tech solar projects that have failed.
If large solar farms and rooftop solar panels aren’t 100% effective, what makes you believe the 1800-watt solar generator you purchased online will be?
Claims Made by Solar Generator Sellers and Manufacturers
Marketing sells. And it can take a lot of research and digging to see past marketing claims and separate truth from fiction.
To save you time, we’ve done the work for you. Keep reading some of the most common claims about solar generators and the real truth about this problematic product.
Claim #1: Completely Reliable and Good for Prolonged Power Outages for Weeks
Solar generators are NOT completely reliable.
Let’s start with the fact that many solar generators only operate at temperatures between 32–120 °F (0–49 °C). What happens if you live up north or experience an unusually cold winter one year?
When you look at the operations manual fine print, many say to keep the unit out of rainy, damp, or snowy conditions. The solar generator is water-resistant, but should not be exposed to rain or submerged.
That limits use right away—especially use in survival situations.
In addition, most solar generators come with only one solar panel. Even if the battery on the unit might be adequate, companies are selling kits with an inadequate number of solar panels.
Trust us, one solar panel isn’t going to cut it.
You must attach several solar panels to get significant power out of your generator.
Companies know you need more than one panel, so they plan to upsell you more to get the solar generator to function properly. Read the fine print, and you’ll find that manufacturers say it’s best to add more panels and “daisy chain” them together to double or triple your power.
It gets very expensive…fast.
Claim #2: Will Power Critical Appliances
A solar generator won’t power critical appliances like you think it will.
If you want to back up a small refrigerator and power a few lights, then 1,500. 1800 watts might be sufficient to handle that—that is, if you have enough solar panels and batteries.
If you have any large electrical appliances such as a range, electric water heater, electric dryer, or an air conditioner, which uses 4,500 watts or more just to run, a 1,500. 1800 watt solar generator won’t even come close.
With 1500 watts, you’ll barely be able to run a small microwave.
A 1500-watt solar generator wouldn’t even heat a small room. You’d drain your battery long before it was adequately heated. You could run an electric blanket for a couple of hours per day, but chances are that’s not on the top of your list when considering a solar generator to keep your household going during a blackout.
Claim #3: Keeps Fridge Cold for Over 16 Hours on a Single Charge
Chances are, you want your refrigerator running day and night. The problem with this claim is that if you have a 100-watt solar panel, it will put out about 500 watt-hours during the day.
When night comes, the solar panel will do no more than keep your battery near empty… and it will not last through the night.
It’s impossible to run a fridge that takes 1,500 watt-hours per day with a solar panel only putting in 500 watt-hours.
Claim #4: Fast Charge Times
Most solar generators require 4-10 hours of charge time in the sun or 3.5 hours if plugged into a power source.
Let’s get this out of the way first: If you want a solar generator to help you and your family survive a disaster or blackout, plugging it into a power source isn’t a critical selling point.
The issue with the “fast charge time” claim is that 4-10 hours of sun to charge your generator isn’t actually fast at all.
Not to mention that for a solar generator to work effectively, it requires you to live in a location that gets full sun all day. Sorry, Alaska!
Northern US states where the sun sets earlier in the winter will also likely struggle to charge solar generators. Plus, if you live in a colder climate, the solar generator may not work below 32°F.
Claim #5: Free Power from the Sun So You Can Run Most Important Devices
Yes, solar charging is free, but there’s a lot more to it. To put it bluntly, you may NOT be able to run your most important devices.
Remember, to work effectively, the panel(s) need full sun all day long. If 25% of the panel is covered by trees providing shade and filters the sun, you’re going to lose 25% of the panel’s output.
As the angle of the sun changes, you may need to move the panels manually throughout the day. What a chore.
Output assumes direct sun and you’ll probably have to move the panels around during the day to achieve that.
In some locations, you could spend every 15 minutes moving the panels around. Who has time to play with panels all day—especially in a disaster situation?
If you have more than one panel, you can angle them differently to maximize sun exposure… but again, most solar generators are sold with just one panel.
If you’re using a solar generator to power appliances during the day, you’re sucking the juice out of the battery pack at the same time it’s trying to charge, and you may not be able to put more juice back in to get the battery meter up.
Claim #6: Will Keep CPAP Oxygen Going During Blackouts
Sure, a solar generator can power these important devices, but for how long AND with what else drawing power from the battery?
The majority of CPAP machines on the market use between 30 to 60 watts of power. And people use them at night, which means you have to make sure you have enough power in the battery to last the night. If the next day isn’t sunny, you may not be able to charge again for the following evening.
Typical oxygen machines draw around 4 running amps and run on 120 volts. The motor inside the concentrator runs continually so that it has an average of 480 running watts.
Again, while you may be able to run it, you won’t be able to run it continuously without extra panels, moving panels around throughout the day, and sacrificing the use of other appliances and lighting your home.
Claim #7 We Have a Superior Battery
Solar generators are nothing more than a battery you can hook up to solar panels. That’s it.
There is no battery that will do everything you want (as many solar generator sellers claim). Another thing manufactures and sellers aren’t forthcoming about is that many solar generators require battery maintenance every 3-6 months to keep the battery in optimal condition in standby mode ready for use.
Solutions to Power Your Home When Disaster Strikes
Before you make a decision on what to purchase, you need to figure out what you will need a generator for and then figure out what type will work best to meet your needs.
Here are 5 alternatives to solar generators:
- Whole house generator – Our top alternative is a whole house generator. Whether you select propane or natural gas to power it, it’s a much more reliable solution to keep your home running during an emergency.
- Natural gas generator – For roughly the same amount of money, you can install a natural gas generator that can power a whole home. While it may be pricey to set up initially, it is rather inexpensive to run since natural gas is cheaper than other types of fuel. The downside is that the generator must be connected to a pipeline to run, which will require homeowners to be very strategic about planning where to place it and how to use it. On the flip side, natural gas lines are very infrequently disrupted in comparison to the power grid.
- Diesel generator – Diesel generators are a combination of a diesel engine and an electric generator. Diesel generators use fuel to run, produce a significant amount of power and are less expensive than natural gas generators. Another pro of diesel generators is that they can be run anywhere, such as on construction sites and ships. The downside is that they are expensive and pretty loud when running.
- Inverter generator – Inverter generators use fuel to convert DC power into AC power, which makes it a safe choice for more sensitive electronics. They tend to be smaller and more portable than other types of generators. The downside is that they are not as powerful as large generators.
- Chafing fuel – Another alternative to a generator is chafing fuel. Typically, you see chafing fuel being used to heat or warm food. They can also be used in small survival stoves. Given the small size, they will only provide a limited amount of fuel for heat for a short period of time.

Can a Solar Generator Power a House? (What You Need to Know)
As an Amazon Associate, this site earns commissions from qualifying purchases. For more details, click here.
if you search for “can a solar generator power a house”, you’ll find articles that say yes, it’s possible. But they don’t tell you how it is possible or how many you’ll need. You will just be shown solar generator reviews, most of which are under powered. Yes, a solar generator can run a house, but it’s not that simple.
It will take four 2000 watt solar generators to power a house and run essential appliances. You can increase the generator capacity by adding solar panels or batteries to the system.
How Much Solar Generator Power You Really Need?
You’ve probably read claims that a single solar generator or power station is all it takes to power a home, but the truth is, that is not enough. We will show why you need at least five to seven solar generators to power an entire household.
The average home consumes 877 kwh per month. That is 10,649 kwh a year or about 30 kilowatts a day. 30 kilowatts is 30,000 watts. The biggest commercially available solar generators have a capacity of 2000 watts, like the Bluetti AC200P. You can run a lot of appliances with 2000 watts, but that is barely enough for a typical air conditioner that requires 1800W running watts.
A mini AC unit will reduce your energy needs, more so if you use a small fridge (or camping utilities). Because people have different requirements, you should find out how many solar generators are needed in your case. Before you buy a solar generator, decide what you’ll be using it for. Here are some guidelines.
- 2000W to 4000W; RVs, small to medium size homes with only essential appliances running
- 5000W to 7500W: for emergency backup power in a large house
- 8000W to 10000W: run most household appliances
If you cannot get your hands on anything other than a 2000W solar generator, do not fret. You can add more batteries to the system until it reaches the energy level you need. Or as stated earlier, use solar panels for extra power. Yu can for example, combine a 2000 watt solar generator with a 2 or 3 Mighty Max 500ah 24V AGM Batteries.
Again these are estimates based on the average watt usage in homes. Yours might be completely different so follow the steps below to calculate what solar generator size is required.
How to Find Out What Solar Generator Size You Need
Let us start with the basics. Solar generator power is measured in watts. All you have to do is figure out the total number of watts you use every month. Add 10% or 20% more and you have a good idea of how much generator power is needed.
Appliance power consumption is measured in watts or amps. Their power consumption will be on the manual or on the device itself. Most appliances use 120 volts.
Watts / volts = ampsAmps x volts = watts
For instance, a refrigerator label might say that it consumes 7A (amps) at 120V (volts). 7A x 120V = 840 watts.
- If you’re going to power your entire house, check your monthly bill and look for the kwh usage. Use that as a guide for what solar power station to buy. If you only want to run critical appliances only, go to the next step.
- Write the appliances you want to use during a power outage. Lighting, refrigerator, heater, AC etc. Essential appliances means different things for different people, so create your own list.
- Add the total watt usage of the appliances you wrote down.
- Pay attention to the running watts and starting watts. A fridge may need 1500W to start up, then the demand goes down to 100-200wh. A generator must match or exceed both the running and starting watt requirements.
- Get a generator that has a bit more power than your requirements. One, you’ll never know when you’ll have to run another device. Generators that always run on full load have short lifespans. Third, it puts a strain on the system.
If your total appliance wattage is 5000W, get a 5200-5500W generator. If it’s 7500W, get an 8000W unit. It never hurts to have more power, but running an underpowered generator can cause serious damage.
House Appliance Generator Power Consumption
We have a comprehensive appliance watt usage here, so we’ll just cover the essentials. A 5000W-7500W solar generator can run vital appliances like the fridge, freezer, heater, water pump and lighting. A 3000-4000W solar generator will be sufficient in this instance.
Here’s a table of common household appliances and power consumption.
|800W Microwave Oven
|1/2HP Sump Pump
|10000 BTU AC
The information on this table gives you an idea of the average power consumption of those appliances. Always check the actual watt / amp use on the appliance.
How Long Can a Solar Generator Keep Running?
Solar power stations function like traditional generators. They spring into action when the power goes off. A solar generator can keep running as long as there is enough power being supplied. Theoretically it can run infinitely.
Let us take the Titan generator for instance, which can generate up to 2200wh continuous power and comes with a 3000W pure sine wave inverter. It has two solar panel inputs good for up to 2000W.
If your solar panels produce 2000 watts, connect it to the generator and you have continuous power supply. The panels probably won’t be able to recharge the generator fast enough, but there will be power available. Also you can recharge the Titan by AC or DC outlet or 24V battery to keep the power going.
You can also attach several batteries on the generator for extra power. Most of these generators accept only lithium ion batteries because it provides the best results. In some solar power stations there is no limit to the number of batteries you can stack. Keep this in mind if you want to run an RV with a solar generator.
You can double these figures for a 2000W solar power station. If you add batteries to the generator, you will be able to run more devices. You probably won’t be using these electronics this way either, so they won’t consume so much power. You can use the available power to run other appliances.
A 2000W solar generator can:
- Charge a laptop for 40 hours
- Run several kitchen appliances
- Charge a smartphone for 300 hours
- Power a 50″ TV for 50 hours
- Power a refrigerator for 30 hours
The bottom line is you can keep a solar generator running continuously provided there is a power supply. This setup requires a lot of power true, but it can be done. it comes down to how much of your house or RV you ant to run on solar.
How to Install a Solar Generator
Installing solar panels on an RV is straightforward, but for homes it’s more complicated. The installation process will depend on how much solar power you intend to use.
If it’s for camping / RV, you can do it yourself. Charge the generator and connect your devices and appliances to the appropriate inputs, i.e. DC, AC, USB. Remember to fully charge the batteries and follow the instruction manual.
Powering an entire house requires a powerful generator and numerous battreies. You’ll also need to install solar panels on the roof as an additional power source. That’s best left to the professionals, who will be happy to install the generator as well. You can plug appliances directly to the generator if it’s going to be the main power source. If your home is on the power grid, connect the generator to the power supply.
What Solar Batteries Do I Need?
A grid tied solar system does not need batteries. An off the grid system should have multiple batteries for generator stacking. We have an in-depth guide comparison for different solar batteries, but lithium ion is the best. You can stack an unlimited number of lithium ion batteries on Titan generators. Other generators may not allow it.
The more batteries you add, the more you increase the generator’s power. The disadvantage is the weight. Connect several batteries and the weight can reach hundreds of pounds. Powerful solar panels can reduce your dependence on multiple batteries.
What Inverter Size Do I Need?
Solar generators already have an inverter, so you don’t have to worry about that.1000W-2000W power stations use pure sine wave inverters to provide the best performance. If you are adding batteries, make sure to connect them to the inverter and to your power grid (if applicable). Don’t forget to connect the circuit breaker to the battery wires.
Plug the inverter into your AC fuse box and wire the solar generator to the inverter. This configuration allows you to go back to electricity if solar power is insufficient. if you’re living off the grid, you must have fully charged batteries in reserve.
The inverter should be connected to your solar panels. The required connectors and cables should be included in your solar panel kit. The charge controllers are built into the generator so no need to buy one.
What Solar Panel Size Do I Need?
it depends on the size of your solar generator and how long you’re willing to go without full power. Going back to our example: if you want to run basic appliances only, 5,000-7500W should be enough. You can get that power from a solar power station with several attached batteries.
You can supplement that system with 8 x 250W solar panels. One 250W panel can produce 1000-1300W with 5-6 hours of sunshine. Eight of these and you have 8000W a day, enough to keep the generator charged. With this setup you can run the solar panels all day and use the generator at night. When the generator gets depleted you use the solar panels to recharge it.
Running a house on solar generators is challenging but feasible. It comes down to how much of the property you want to run on solar and what your specific needs are. Once you have done the planning, it’s relatively easy to set up the generator system and run your appliances.
What Appliances Can A 7500-Watt Generator Run? – A Helpful Guide
It’s dinner time, the wind is blowing outside and then suddenly it’s dark. The power is out and your pot roast is in the oven with 20 minutes to go.
You have a 7500-watt generator to keep the oven going, the hot water flowing and the heat on during this unexpected power outage.
A 7,500 watt generator is a great size for most homeowners. With a 7,500-watt generator, you can power up most household appliances including your refrigerator, hot water heater, well pump, freezer, light, and oven, depending on the units you have. In this article we will show you how to calculate exactly what a 7,500 watt generator will run in your situation.
Okay now back to our main topic, the 7,500-watt generator. In this article I am going over how to choose a generator, determining the energy load you need, how many appliances a 7500 watt generator will run, and a some general safety tips to remember.

Choosing a Generator
If you are in the market for a generator, you may have noticed there are a variety of different sizes and wattages available on the market today.
It’s overwhelming how many configurations there are when it comes to generators. Let’s get into the basics of generators to help you narrow down your choice.
Generators are a backup power source for your home. You can have it hardwired into your home to automatically kick in when the power goes out, or you can have an electrician patch in a plugin for the generator that you physically turn on when the lights go out.
Having the generator hardwired into your house typically is more expensive. Hiring an electrician to safely hardwire or provide a plugin for your generator is the best way to make sure the wiring is done safely and correctly.
Don’t try to do this yourself- a wrong wire or plug can cause a house fire or carbon monoxide poisoning. It’s just not worth it. Ask your electrician about a transfer switch on your electrical panel to make plugging in a generator easy and safe during an emergency!
A generator is sold based on wattage. A 7,500-watt generator means that it can safely power appliances and other power need that total up to 7,500 watts. The higher the watts, the more appliances, tools, and lights the generator can power.
The physical size of the generator often correlates with the energy load it can handle. The more watts the bigger the generator. The smaller the watt load, the smaller the generator. You get the idea.
A 7,500-watt generator is a popular choice for homeowners because it’s not too big and it provides just enough power for the essentials: keeping food cold, hot water, flushing toilets if you are on a well, taking hot showers and staying warm.
The best way to determine what size generator you need is to add up the wattage of all the appliances, lights and other power needs. The total of your power needs will determine what size generator you will need. The more power you need, the more expensive the generator.
A 7,500-watt generator will cost you a couple thousand dollars. It’s an investment, but it can be a lifesaving tool as well. If the power goes out in the middle of January in Minnesota, I bet you aren’t going to be thinking about how much that generator cost you. You’re just going to be happy you have a way to keep your family warm.
Determining Energy Load
A 7,500-watt generator is a great choice to run the basic appliances and a few extras, like a toaster, coffee maker, and blender. Although, I’ll be the first to admit I don’t really see powering a coffee maker as an extra.
I think of it more like a need! But, that’s just me. To determine if this is the right generator for you, first take inventory of all the appliances, heaters and pumps you can’t live without.
You can find the true wattage of an appliance on the appliance itself or in a manual. When in doubt, contact a professional electrician to determine the wattage for you. This is important. If you overload the generator with too much wattage, the generator could overheat and wear down quicker.
Overloading a generator could also damage wiring in your home and make it more difficult to get power to your appliances. Don’t overload your generator! You may need to buy another one if you do. Overloading a generator greatly reduces its lifespan.
There are two numbers you need to take into consideration when determining how many appliances you can power on a 7500-watt generator. There’s the running wattage and the startup wattage. The running wattage is how much power is required to run the appliance.
The startup wattage is how much power is required when you turn on an appliance, pump or furnace. The running wattage and the startup wattage are not always the same. You need to consider the startup wattage when determining the total power load for a particular appliance.
Let’s say you have an entire freezer full of meat, berries and other yummy food and the power is out. The power company expects to have power restored in the next five days. It’s the middle of summer and you can’t risk losing all that food. So, you turn on your trusty generator and power it up.
How much wattage does the freezer need and can I turn on my refrigerator too? Let’s say the running wattage of your freezer is 720. But, to start the freezer it needs more power. In fact, the startup wattage is 1890 for the freezer. So, this is how much total wattage is needed to start your freezer.
Walk through your home and make a list of all the appliances, pumps and heaters you need to comfortably weather your next power outage. Write down the running wattage and startup wattage of each appliance and add up all the numbers. You’ll be surprised at how many appliances you can run on a 7,500-watt generator.
How Many Appliances
The Basic Calculation: The simplest way to calculate this is by adding the amount of watts each device you plug into it draws, compared to what the generator will handle. For example one 60 watt light bulb draws 60 watts of energy to run. (See my above video about the solar generator for an example of this.)
This means at full capacity a 7,500 watt generator will power 125 60 watt light bulbs (7,500 / 60 = 125). Both my refrigerator and chest freezer draws between 12 and 40 watts each to run, and about 800 watts when starting. My space heater uses 1600 watts, so you want to avoid running things like electric heating devices (space heaters, electric oven, hair dryers etc.).
So to calculate what size generator you will need, simply add up the watt usage all of the devices you will be wanting to run (your emergency necessities) and plan accordingly. A good rule of thumb says that you should never operate a generator at its maximum power output for more than 30 minutes.
This is why a generator’s rated power is usually a more reliable measure of generator power. Rated power is the power that a generator can produce for longer periods of time, which is typically no more than 90% of its maximum power.
Also remember that the more load you put on the generator, the more fuel it will consume. So in an emergency if you have limited fuel you will want to conserve.
For most homes, if you avoid things that produce electric heat, you can easily run all the necessary appliances with a 7,500-watt generator. You may not be able to run everything at the same time (again you can calculate this by adding up the watts as described above). You may need to unplug some appliances to run others, depending on how much power those appliances you.
Another thing to remember is starting wattage. Some devices use more watts to start running than they do once they get going. So you would want to allow enough room for the starting wattage of the different devices when you do your calculation, so that you do not overload your generator. Once the big items are running, if you have to you can then turn on other smaller items.
Example Scenarios: Let’s run through a couple different configurations to show you how many appliances you can run with a 7,500-watt generator. You can also easily do the research and crunch the numbers for your specific needs. Most power companies will offer wattage information about appliances and generator safety tips as well.
Okay. Let’s get started. When the power goes out you are going to want lights, refrigeration, freezer, water heater, well pump and a way to make food. Those are pretty much the basics. Let’s start with these appliances and see how much power they need to operate.
Refrigerator: A typical refrigerator needs 132-192 watts to run (mine is smaller than normal), but needs between 800 to 1,200 watts to start it. If you have a separate freezer, it will be about the same.
Water Heater: An electric water heater element will use between 1,100 and 4,500 watts depending on weather the element is 120 or 240 volts. I could not find how many watts they take to start them. A natural gas water heater takes about 1,500 watts to start the unit, and around 500 or so watts to run.
Furnace: A typical home gas furnace needs between about 500 to 2,400 watts to start, and between about 300 to 900 watts to run, depending on the horsepower of the unit. An electric heat furnace takes between 10,000 to 50,000 watts to run, depending on its size.
Well Pump: A well pump only uses about 150 watts of power; however, it takes a whole lot of power to start it up. In fact, according to my local power company, it takes 1950 watts to start the pump. Yikes, that’s a lot of power. You can see how easily the watts add up.
Electric Oven: A typical modern electric oven can use between 1000 to 5000 watts, with an average using around 2,400 watts on medium to high heat.
When determining what to power during an emergency, think about needs versus wants. You need water, food and a warm place to live. Yes, I’d love to power on the television and watch reruns of Gilligan’s Island, but it’s a want, not a need. And I’m certainly not going to be giving up my hot water for a sitcom. Again, you can always turn off appliances and turn on other appliances for a one-time use.
You can change what you power throughout the day and night, depending on the weather and your needs. If you live in Arizona, you won’t need heat, you’ll need air conditioning. A room air conditioner uses 1,412 watts. Central air conditioners require 5,400 watts to run and 7,200 watts to start. There goes your watt budget.
Here’s a quick guide of wattage use for basic appliances: microwave-100 running wattage, television-50 to 400 running wattage, coffee maker- 1,200 running wattage, radio-225 running wattage, slow cooker- 250 running wattage, computer-300 running wattage, washing machine-1,150 running wattage and 2,200 startup wattage, blender-375 running wattage and 500 startup wattage, air source heat pump- 5,400 running wattage and 7,200 startup wattage.
For more accurate numbers, check with the appliance manufacturer or a local electrician. Your local power company is also a great resource for determining wattage of your appliances.
With a 7,500-watt generator, you can run a lot of smaller appliances or a few large appliances, heat and water pumps. Determine what is most important to you during an emergency and power those appliances and comforts accordingly.
In general, a 7,500-watt generator should get you through the next emergency comfortably. Don’t expect to live like you do when the power is on. You will need to make sacrifices, even when you have a generator. Focusing on powering what you need to survive and you will be just fine!
Now, that you have a generator you need to make sure you know how to safely use the generator. As I mentioned earlier, you need to have a transfer switch installed. A generator transfer switch at the base of your meter will protect the power from “back feeding” onto lines. When power back feeds, a current goes back into the electrical lines and it could seriously injure or even kill crews working to restore power.
Always hire an experienced electrician to safely install a transfer switch for your generator. Never plug a generator directly into an outlet in your home. This can also create back feeding, ruin your wiring and potentially cause a fire.
Also never run your generator from within your garage, unless you have proper ventilation. If you design your garage correctly, and have professionals who know accepted safety standards, all things are possible.
When you have safely connected your generator to your home, start by plugging in the largest appliance first. From there, plug in appliances, lights and other needs one at a time. Remember, do your math first to avoid overloading the generator. Also, make sure you have the right extension cords.
A three-prong extension cord works best for large appliances. When using a generator, make sure it is in a dry location protected from rain, snow, and other wet weather.
Never under any circumstances should you ever run a generator inside your home or garage! Generators use gasoline to operate. Gasoline creates toxic fumes like carbon monoxide that can be deadly. Never use a gasoline powered generator inside your home! Your life depends on it.
On that note, never BBQ inside either. I know this sounds obvious, but it seems like every year during a power outage people die from using BBQs or generators inside their homes. Don’t be a statistic. Use common sense when operating your generator!
What Can You Run on a 7500 Watt Generator?
Being without electricity for a couple of hours is annoying but tolerable. But what if there is a huge storm that lasted for a few days? In such situations, you will not have access to power for days. Now, this can cause a lot of damage to both homeowners and small businesses. A portable home generator is a very useful device during prolonged blackouts and power outages. It supplies electrical power so that you can run all the important electrical appliances without depending on the grid. There are several sizes and types of backup generators. If you want a balance between budget and power, then a 7,500-Watt Generator is a decent option. But an important question is what can you run on a 7,500-Watt Generator?
If you are planning to buy a 7,500-Watt Generator or shortlisted a popular 7,500-Watt Generator, then you will be wondering what appliances can you run using this generator.
A good rule is to calculate the size of the generator based on your requirements beforehand so that you won’t spend too much on a large generator or get a small generator that couldn’t handle the devices.
Nonetheless, if you are interested in knowing what can you run on a 7,500-Watt Generator, then this guide is just for you. Whether you want to use the generator to power essential appliances in your home or run various power tools in a worksite, then go through this guide.
A Brief Note on Generators
Portable gas-powered Generators are one of the simplest devices that produce electricity. In its basic form, a generator consists of a gasoline engine, an alternator, and some additional electrical components and outputs 120V AC Supply.
Generators are also the cheapest way to provide a backup power supply for your home or business. You don’t need complex installation or wiring. You can access the power from the generator using good-quality extension cords.
Choosing a Generator
Wattage! While there are several factors and parameters of a generator, the power rating in Watts is the main way to classify generators. You can get portable generators in several power ratings starting with as little as 1,000 Watts and going all the way to 15,000 Watts.
So, how to choose a generator? We already made a guide on Sizing Portable Generators. Check that out for more information. But essentially you need to make a small calculation using the Running Watts and Starting Watts of all the appliances you want to run and also the corresponding rating of the generator.
If you are unfamiliar with the terms Starting Watts and Running Watts of a generator, then here is a brief overview. The Running Watts of a Generator are the continuous power it can deliver for sustained periods.
The Starting Watts of a Generator are the surge power (or sudden jolt of power) that it provides while starting a motor-based appliance. Some common motor-based devices are Air conditioners, Refrigerators, Water Pumps, some power tools (saws, drills, hammers, etc.), Dish Washer, etc.
When the motor in these devices starts from a complete stop position, it will draw a large current (which can be two or three times that of the normal current) to kick-start the rotation. As a result, the power draw while the motor starts is also twice or thrice its normal power consumption.
The generator must be able to deliver this power (or choose the generator with a sufficient Starting Watts rating), even though this high power draw will be only for a couple of seconds.
Coming to the 7,500-Watt Generator, this rating can be the Running Watts or the Starting Watts. Does it make any difference? Yes. A big difference. If the 7,500-Watt rating is the Running Watts specification of the generator, then you will have a higher starting watt rating (usually 9,500 Watts or 10,000 Watts).
But if you choose a generator with Starting Watts rating of 7,500 Watts, then the Running Watts will be even lower (usually in the 5,500 Watts to 6,000 Watts range). So, you will be limited to a low continuous power.
We recommend you choose a generator with 7,500 Watts of Running Power (if your budget permits it).
Why 7,500-Watt Generator?
There are larger generators that can produce 10,000 Watts or more power and there are also smaller generators with 5,000 watts or less power rating.
But the 7,500-Watt Generator hits the sweet spot on different aspects of buying a generator. We will see more about that now.
If you want to run larger appliances such as refrigerators, air conditioners, freezers, heaters, etc. using a portable generator, then the 7,500-Watt Generator can provide the power to run those devices (not all at the same time though).
This might not be possible with a smaller generator, say with a rating of 5,000 Watts. You could run one or two high-powered appliances with a small generator but not more than that.
The next benefit of choosing a 7,500-Watt Generator is savings. Take a look at the price of some popular 7,500-Watt Generators and compare them with higher power generators, something like a 10,000-Watt Generator or more. The price difference is huge.
If you are certain that your power requirements won’t exceed 7,500 watts, then there is no point in spending the extra money for a 10,000-Watt Generator. This way, you could save money while making the initial investment.
What Can You Run on a 7500-Watt Generator?
Coming to the main topic of discussion, if you were to select a 7,500-Watt Generator, then the first question you get is, what can you run on a 7,500-Watt Generator? To answer this question, we have to once again visit the terms Starting Watts and Running Watts.
The following table shows some common household, garage, and workshop appliances, devices, and tools along with their typical power consumption ratings. You can observe that we mentioned both the Continuous Power i.e., the Running Watts of the device, and also the additional Surge Power it draws i.e., the Starting Watts of the device.
|Household Appliances, Devices, or Tools
|Rated Power (Continuous Power or Running Watts)
|Additional Surge Power (Peak Power or Starting Watts)
|Incandescent Bulb (100-Watt)
|LED Bulb (9-Watt)
|Window Air Conditioner (10,000 BTU)
|Sump or Well Pump (1/2 HP)
|Room or Space Heater
|Furnace Blower (1/2 HP)
|Garage Door Opener (1/2 HP)
|Microwave Oven (1.1 Cubic Feet)
|Electric Clothes Dryer
|55” OLED TV
|Air Compressor (1/2 HP)
|Circular Saw (7” Blade)
|Table Saw (10” Blade)
These power ratings are typical values and for exact information on both the Running watts and Starting Watts of a device, do refer to the manufacturer’s manual, catalogs, or website.
With this information, you can make a list of all the devices you want to run off of a 7,500-Watt Generator and make some simple calculations. Let us take a couple of scenarios and see what can you run on a 7,500-Watt Generator.
In the first case, you want to run all non-motor devices i.e., devices or appliances that do not have any additional Surge Power (or Starting Watts) requirements.
These devices include light bulbs (both incandescent if you are still rocking them or LEDs), TV, Stereo Systems, Infrared Space Heaters, Computer, Laptop Chargers, Electric Iron (Curling Irons, Hair Dryers, etc.), Electric Water Heaters, Humidifiers, and other similar electrical appliances.
Now, after making a list, add the running watts of these devices and make sure that this number doesn’t exceed 7,500 Watts. A good rule is to leave 10% headroom for the generator, so 90% of 7,500 watts is 6,750 Watts. So, the power consumption of all the devices must not exceed this value.
We cannot imagine our day going on without a motor-powered device. Be it refrigerators, freezers, power tools, air conditioners, etc., all these appliances have some form of a motor in them that pull a huge surge power when starting after a complete shutdown.
So, the next scene is going to be very interesting. Even though you use moto-based appliances, there is a good chance that we won’t be using them all at the exact same time. As usual, make a list of all the appliances you want to run with the generator.
Now, take the device with a higher starting watts rating and add it to the sum of the running watts of all the devices. In this way, you can estimate the maximum surge power the generator must provide in the worst case. Make sure that this rating is less than the Starting Watts of the 7,500-Watt Generator (which will usually be in the range of 9,000 Watts to 9,500 Watts).
You can run several small devices and a couple of large motor-powered devices with a 7,500-Watt generator without much worry. Just make sure that you don’t start two power-hungry appliances at the same time and that the total power draw of all the devices doesn’t exceed the rating of the generator.
We know this isn’t the direct answer you are hoping for as it is very difficult to generalize the power consumption of different households. But if you understand the basics of how to estimate the size of a generator, you don’t need to be a genius to calculate the necessary power rating and choose a proper generator size.
In the case of a 7,500-Watt Generator, assuming this rating is the Running Watts of the Generator, just make sure that the overall power draw of all the devices, tools, and appliances doesn’t exceed this number.
Things to Consider Before Choosing a 7,500-Watt Generator
As a bonus, here is a brief overview of all the things you need to consider before choosing a 7,500-Watt Generator.
Starting Watts and Running Watts
The first and most important parameter or specification that you need to FOCUS on is associated with the power rating of the generator. We usually have two ratings in the form of Running Watts and Starting Watts.
We already discussed a great deal about these two ratings but in a nutshell, Running Watts is the power output of the Generator for continuous operation while Starting Watts is the surge power that the Generator can supply when any motor-powered appliance starts.
In the case of a 7,500-Watt Generator, make sure that this refers to the Running Watts and not the Starting Watts. In this way, you can run multiple powerful devices in the event of a power outage. If 7,500 Watts is the Running Watts of the generator, then it will have 9,000 to 9,500 Watts of Surge Power capability.
Type of Generator
There are different types, styles, and sizes of generators. First, there are conventional and inverter generators. Next, we have generators that run solely on gasoline but we also have that run on natural gas and propane.
Nowadays, it is very common to find several manufacturers producing dual-fuel generators that run on either gasoline or propane.
Diesel fuel generators are usually large, heavy, and powerful and are common in commercial applications. For residential, camping, or worksite needs, you need to look at the previously-mentioned fuel options to get a decent generator within budget.
Another important thing you need to consider is the form factor of the generator. As 7,500 watts is neither big nor small, you can get portable generators. The benefit of these generators is you can easily move from place to place or carry from one site to other without any effort.
Ports and Outlets
The main purpose of a generator is to provide electric power to appliances of different sizes. Hence, you need to look at the number and types of outlets the generator offers.
This way, you can plug the appliances directly into the generator without hardwiring it to your home’s electrical system. Some common ports and outlets are 120V 20A household outlets, heavy-duty 120V/240V 30A outlets (L14-30R and L5-30R), and many others.
There are several other factors such as fuel tank capacity, running duration, starting system, noise, efficiency, warranty, etc.
