    Going out on a hike, camping trip, fishing trip, or some other outdoor excursion can be an excellent way to enjoy nature, get away from civilization, and unplug for a little while. Sometimes, though, it can make life a little easier in the wild if you bring a little bit of that civilization with you with a portable solar power supply for camping.

    The catch is, any technology you bring has to have power, and it’s not usually readily available when you’re out in the woods (or the desert, or the tundra, or the mountains, etc.). So if you’re planning on bringing some tools or toys on your next trip to the wilderness, you might want to think about bringing some portable solar power along with you.

    Why You Want Power

    There are a number of reasons you might want a portable solar power supply for camping. Those reasons tend to be forms of convenience. Obviously, you may want some power to recharge your phone (your lifeline out in the wilderness), and possibly your tablet, if you chose to bring it, but it doesn’t stop there.

    Many pieces of camping or trail gear can be run on some sort of power, be it rechargeable batteries or straight up plugging it in. This includes flashlights and torches, camping stoves and hotplates, heaters, fans for blowing up an air mattress, and so on. In all of these cases, you’ll need to juice your devices up if you want them to work.

    Basic Power Options

    For the casual outdoorsman (or woman), there are some basic portable solar power supplies for camping, such as battery packs (for your phone or tablet) and portable power packs (which come in various sizes). Battery packs range from a phone recharge or two to packing several days worth of power, all of which is measured in milliamp hours (mAh). To get an idea of how far it will get you, compare the mAh on the battery pack to the battery on your phone.

    Power packs bring more juice, but battery packs have to be recharged once they run out. An even better solution is the use of portable solar-powered supplies like a Go Mini Solar Kit. which can provide power anywhere.

    Advanced Power

    What the serious trailblazer really needs is power that can be accessed anywhere, even when they’re off the grid. At Humless. we offer reliable, rechargeable portable solar power supplies for camping that are unparalleled. Using clean solar power, accessed with portable solar panels, you can have as much power as you need for as long as you need it, wherever you go.

    Steps to Build a 5,000-Watt Solar Generator

    Building a solar generator can seem like a daunting task at first glance. But with some basic knowledge and elbow grease, you can create your own reliable source of power! And who knows, maybe this project could even spark (pun intended) a career change for you. After building one yourself, you may want to become an electrical engineer, and before you know it, you might have a Ph.D. and end up teaching others! But we digress.

    Join us as we break down how to make a 5,000-watt solar generator for less. But before we get into all that good stuff, what is a solar generator?

    What is a Solar Generator

    A solar generator is a portable battery storage unit. It’s like the power bank for your phone, except it can power an entire house. It works with solar panels to give you power on the go.

    A solar generator is ideal for outdoor activities like camping, off-site work, and even topping up the batteries on your EV. Solar generators can come in handy during emergencies like blackouts during natural disasters. A solar generator is what you need in a zombie apocalypse.

    Benefits of Building Your Own Solar Generator

    You can easily walk into a store and buy a fully functional solar generator, but where’s the fun in that? And besides, ready-made solar generators cost thousands of dollars. What if I told you, you could make one at home for less and have fun while doing it?

    Below are some of the benefits of building your own solar generator:

    Solar Generators are Greener and Quieter Than Gas Generators

    You’ve probably stumbled upon a fossil fuel generator. They are dirty and loud. Taking them outdoors is like an insult to nature. They pollute both the air and the sound of nature. A solar generator is not guilty of these crimes. It’s quieter and greener.

    Solar Generators are Safer Than Gas Generators

    Gas generators use fossil fuels. And as we know, fossil fuels are explosive. Accidents involving gas generators could be lethal. If not cared for, gas generators can catch fire. Solar generators don’t catch fire as easily.

    Zero Running Costs

    To run a gas generator, you need to buy gas. And as you know, gas is just a few digits over expensive. Solar generators only need energy from the sun. And the last time I checked, that was free.

    Easy to Repair

    The best thing about a DIY project is that you know where everything goes. So if any of the components grow faulty, you can easily repair or swap them out.

    Gives You a Sense of Pride and Accomplishment

    Accomplishing any goal gives you a dopamine hit. Imagine how you’d feel after building your own solar generator. I know one thing, you don’t get that feeling when buying a ready-made solar generator.

    Solar Generators are Cheaper Than Ready-Made Alternatives

    Are you debating whether to build a solar generator? Well, here’s one thing to think about; ready-made solar generators are more expensive.

    portable, solar, generator

    If you build it yourself, you’re using your own labor. This factor alone reduced the cost significantly.

    How do you make your own DIY solar generator? Well, let me show you. But first, we’ll need some supplies.

    Materials and Tools

    These are the items you’ll need:

    • 50-Gallon Toolbox (waterproof and secure)
    • 20 Solar Panels (250W)
    • Charge Controller (5 kW or higher)
    • Batteries with a total capacity of 10 kWh
    • 1 Inverter (5,000 W or higher)
    • 2 Fans (120mm)
    • 2 Fan Grills (120mm)
    • 1 Digital Temperature Meter
    • 1 Digital Temperature controller
    • Some Ply Wood

    Design and Planning

    That’s one long shopping list, don’t you agree? But how do you assemble all these components to make a fully functional solar generator? I’ll tell you; by proper planning and execution. And it all starts by designing a workable plan.

    A proper design will reduce your workload by half. It will make assembly easy. And ultimately, the work will feel like putting together a jigsaw puzzle.

    Designing your solar generator involves deciding where all your components will go. Where will you fix your fans? How will you arrange your batteries? Where will you mount your inverters? These are some of the questions that you should be asking yourself.

    The way you plan your solar generator has serious implications for the health and life of the device. For example, you need to keep the heat-emitting components away from the heat-sensitive parts. Or at least place vents and temperature sensors in the right places to mitigate heat buildup.

    Well, how do you build the whole thing?


    Let’s get into the fun part; the build. Here’s how you build a 5,000 W solar generator.

    portable, solar, generator

    Step 1: Determining Your Power Requirements

    Before you build a solar generator, you need to determine your energy needs. It’s called working Smart, and this is why we always start with tis step. But since we know our energy requirement (5,000W), we can go ahead and skip this step.

    Step 2: How Many Solar Panels Will We Need?

    Your energy requirements dictate how many solar panels you’ll need. Let me explain; we know that we need a 5,000 solar generator. We need enough solar panels to feed a 5,000-watt appetite.

    Always remember this; the total wattage of your solar panels should exceed your total energy needs. To feed a 5,000-watt appetite, you need twenty 250-watt solar panels.

    When picking your solar panels, pick those with high efficiency. This winning strategy will maximize your energy production.

    To understand how to calculate your solar panels’ power production, check out this article.

    Step 3: Mount Your Solar Panels

    With your solar panels bought, mounting them is naturally the next step. Figure out how you want to mount them and ensure they get maximum sunlight. You can go either with a fixed mount or a sun-tracking system. It all depends on your budget.

    As for installing your solar panels, you can maximize sunlight exposure by facing them south.

    Step 4: Make Vents

    When the solar generator is functional, heat will be a problem. An effective way of solving this problem is by adding vents to the solar generator. In the design phase, you might have already decided where you want your vents to be. All that’s left is cutting them open.

    Use a saw to cut out the vents. Remember to heed the safety guidelines.

    Step 5: Connect Your Charge Controler

    The charge controller is the intermediary between your solar panels and your batteries. It guards your batteries, protecting them from overcharging. But before they charge your batteries, they need some juice. Connect your solar panels to your 5 kW charge controller.

    Step 6: Connect Your Batteries

    Such a powerful solar generator needs a big power bank. You can choose any configuration you want (lead-acid or lithium-ion) as long as the battery capacity is at least 10 kWh. Place your battery pack into the toolbox. Ensure that you secure it. Our solar generator is mobile. We don’t want a wobbly generator.

    Step 7: Connect Your Power Inverter

    At this point, all our power is in the DC (Direct Current) format; it’s not ready for consumption. We need to convert it to Alternating Current (AC). And how do we do that? By employing the services of a power inverter.

    Connect your batteries to your 5 kW power inverter.

    Step 8: Double-Check Your Electrical Wiring

    A solar generator is still an electrical appliance, and we need to be careful about the wiring. Always use high-quality cables that can handle your solar generator’s load.

    Also, ensure that you’re consistent with grounding. Follow local electric codes and stick to the safety guidelines. If ever in doubt, consult with a professional.

    Step 9: Instal your Monitoring Systems

    When it’s fully functional, your solar generator is like a living, breathing animal. As such, we need to monitor its health. Different monitors will help us diagnose different problems.

    For example, the charge controller is known to emit heat. This heat can build up in the toolbox and can damage our batteries. We need to know the temperature inside the box so we can decide when to turn on our fans.

    We can monitor generator temperature with heat sensors. And you can place these probes in different places throughout the generator. Find the components that give off heat and place your sensors near them.

    And voila, your 5,000-watt solar generator is done.

    Final Thoughts

    Sure, you can buy a ready-built solar generator. Yes, it’s fancy. Yes, it has all bells and whistles. But where is the fun in that? Why don’t you pick up your tools and build one yourself? All you need are the supplies.

    There are many benefits to building your own solar generator. And they include:

    • A DIY solar generator is greener than a gasoline generator
    • Solar generators have zero running costs; you don’t have to buy gas to run it
    • A 5,000 W solar generator could power an entire home
    • A DIY solar generator is easy to repair
    • DIY solar generators give you a great sense of achievement
    • Usually, a DIY solar generator is cheaper than a factory-made equivalent.

    So why don’t you buy some supplies and build yourself a solar generator?

    Generator Sizing Guide For Off-Grid Solar Systems

    Most off-grid solar systems are paired with a generator. Without utility power as a fallback, off-grid setups need a backup plan in case their solar system can’t produce enough to meet the property’s needs.

    Gas generators are used in off-grid systems as a backup charging source to recharge the battery bank when solar can’t keep up with demand. They are also used for backup power in case equipment fails and the inverter system needs to be bypassed.

    Here’s our advice on how to pick a generator for your off-grid solar system.

    Generator Sizing

    As a general rule, the generator should be around 2 times the size of the inverter’s continuous output. For example, a 4,000-watt inverter should be paired with an 8,000-watt generator.

    This is because the generator needs to charge batteries while still powering the loads (appliances using energy). If the loads total 4,000 watts, and the charger is 60 amps at 48 volts, that totals around 7kW of continuous power:

    portable, solar, generator

    60a x 48v = 2,880 watts 4,000 watts = 6,880 watts

    8kW would make sense as a minimum generator size to power the loads and have enough power to charge the battery bank as well.

    It’s a good idea to round up slightly to give some headroom for the generator, especially at higher elevations where your generator is going to lose some of its power. Engines can lose around 3% of their power for every 1,000’ increase in altitude. Make sure you account for this if your system will be installed at a high elevation.

    Can I Use a Larger Generator?

    A larger generator can be beneficial if you have large loads like an air conditioner or a welder that will only be used when the generator is running.

    We frequently sell 12kW and 14kW Kohler generators with our off-grid systems using a 4000w inverter. A larger generator is going to burn more fuel, but otherwise will work fine.

    Can I Use a Smaller Generator?

    Smaller generators will still work, but it typically requires adjusting the settings to limit the battery charger’s output. Most battery chargers allow you to adjust the AC input amperage and charge rate.

    You will need to match the generator’s voltage with the inverter. For example, 120Vac generators should be paired with 120Vac inverter/chargers, while 120/240Vac generators need an inverter that outputs 120/240Vac.

    In the rare case that you are using a three-phase generator or inverter, the same rules apply: the generator’s voltage would need to match the inverter.

    There is one exception we are aware of. Magnum PAE inverters are 120/240Vac but can handle a 120Vac input, provided you turn down the charge rate to 50% or lower, and adjust the AC input amps to match the size of the generator. This is useful if you need an inverter that can output 120/240Vac but are working with a smaller generator.

    Generator Fuel Type (Natural Gas, Propane, Diesel)

    Most standby home generators work on natural gas, propane or diesel. Diesel generators tend to be much more fuel efficient and longer lasting, but the initial cost can be 2-3 times more than a natural gas or propane alternative.

    The Kohler 12kW 14kW generators we sell can work with either natural gas or propane. Off-grid customers typically use propane instead of natural gas, but these models can be configured to work with either fuel type.

    Other Considerations


    Most generators don’t have a warranty that covers off-grid or prime power applications. Check the generator warranty closely to be sure it can be used off the grid.

    Kohler’s 12RES and 14RESA generators are both warrantied for 18 months / 1000 hours of off-grid use (whichever comes first).

    If you need more power, dual 14RESA generators can be combined in parallel with the Kohler Powersync module for 28 kW of output.

    2-wire start

    Off-grid generators paired with solar power systems need 2-wire start capability to allow the automatic generator start (AGS) function to work. When your batteries drop below a certain voltage, the AGS kicks in to turn on the generator and recharge your battery bank.

    Note that 2-wire start is different than electric start. Some generators will have a button for electric start/stop, but they can’t be controlled by a 2-wire signal, which means the inverter can’t communicate with the generator to trigger the AGS mechanism.

    The Kohler 12RES and 14RESA are both capable of two-wire start.

    1800 RPM vs. 3600 RPM

    Most generators operate at one of two engine speeds: 1800 or 3600 RPM.

    The difference is based on engine design and the alternator being used. 1800 RPM generators are generally considered superior because they are more fuel-efficient, but they cost quite a bit more up front. 3600 RPM generators tend to be cheaper but less efficient.

    The Kohler 12kW and 14kW generators we sell are 3600 RPM. They are very durable, reliable and more cost-effective for typical off-grid applications. Kohler doesn’t make any 1800 RPM generators smaller than 24kW, although there may be options from other manufacturers. Be sure to do your research and read reviews to learn about the company and make sure you are getting a quality product.


    When searching for a generator to support your off-grid solar system, keep a few things in mind:

    • Generator output should be 2x your inverter’s output
    • Match generator voltage to inverter voltage
    • Generator must be warrantied for off-grid use
    • 2-wire start is mandatory to work automatically with solar system
    • 3600 RPM generators are more cost-effective, while 1800 RPM generators cost more up front but last longer and are more efficient
