00 Watt Inverter to Generate Your Own Solar Power and Cut Down Your Electricity Bills

We are in an era where the whole world is collectively trying to reduce the usage of fossil fuels. The damage that fossil fuel has done to the world is too high to assess.

Air pollution, land pollution, water pollution, climate changes, global warming are a few direct causes of using fossil fuels. It affects, every living being including plants in the world.

Despite the damage done, fossil fuels are used in many industries to do various types of work. Electricity generation is one of the main uses among other uses of fossil fuel.

Currently, most countries all around the world are trying to move to renewable sources to produce electricity. Solar power is one of the renewable sources which is free anywhere in the world.

There are several ways to harness solar power. They are namely:

Solar photovoltaic (PV) systems are the most popular method to harness solar energy. It converts the sunlight directly into electricity. This method helps the user or power consumers to be totally independent of utility suppliers.

How Can You Use Solar PV Technology to be Independent of Utility Suppliers?

You need an “Off-Grid” solar PV system for the job. The name “Off-Grid” means that you do not have any connection to the utility supplier. Off-grid solar power systems are not connected to the main grid in any way. It helps you to generate the amount of solar power you need at your home and store it in batteries for later use.

Usually, the average household power consumption is around 300 – 400 units a month. This amount is for using the essential appliances like refrigerators, water heaters, and other electrical appliances you use in your day-to-day life.

For an average household, you need around 3000W of solar capacity to power the house for a whole month to be totally independent of the utility supplier.

All that you need to build a 3000-watt solar power system is given in the list below.

• Solar panels to suite the specifications of the 3000 watt inverter
• 3000 watt inverter
• MPPT charge controller aligning to the voltage level of 3000 watt inverter
• Batteries to power your house for a day

We know that solar panels are used to convert solar power directly into sunlight. But we cannot use the power generated by solar panels because it is DC (Direct Current) power. The power provided by the utility supplier is AC (alternating current) power. All the appliances we use in our day-to-day life are designed to work for AC power. DC power is completely useless because we cannot use it.

Therefore, having just solar panels is not enough. The most important component of an off-grid solar PV system is the component that converts DC power into AC power. We call it the inverter. In our case, for a 3000-watt solar system, we need to use a 3000-watt inverter.

How Do You Design an Off-Grid Solar PV System with a 3000 Watt Inverter?

As mentioned earlier, the most important component you need in your 3000 watts solar PV system is the 3000-watt inverter. It is the component that makes the power generated by solar panels usable.

The rest of the components should be designed to meet the specifications of the 3000-watt inverter. The number of solar panels, sizes of cables to use, the battery voltages, and connections are dependent on the inverter specifications.

When the solar panels generate solar power, it is important to store the excess to use later. We have sunlight only in the daytime. But we use electricity throughout the whole day. Even in the night. Therefore, how to generate electricity at night?

You cannot generate electricity at night because there is no sun. Instead, we can store the electricity and use the stored electricity at night.

To do that you need batteries.

How to Calculate 300W Inverter Solar Panel Requirements

The calculation looks simple enough. If your inverter needs 3000 watts, get ten 300 watt solar panels. 10 x 300 = 3000 watts an hour right? Well it is not that simple.

A 300 watt solar panel kit – we highly recommend the Renogy 300W Solar Kit – can yield up to 300 watts an hour. But this assumes perfect weather conditions, the sun is out and no clouds the entire day.

Even in ideal weather, a 300 watt solar panel might reach 300 watt hours only for a couple of hours at noon. After that the output drops down. So it is best to have extra solar panels available.

The calculation formula is:

Inverter watt load x runtime 10% = solar panel size

In the following section we will explain why 10 x 300W solar panels may not be enough for a 3000 watt inverter.

How Many Solar Panels Do You Really Need?

As pointed out earlier, solar panels usually reach peak output for just a few hours a day. So a 300 watt solar panel might average 280-290 watts over five sun hours.

10 x 300W solar panels with an average output of 290 watts each.

The array only produces 2900 watts, which is short of the 3000 watts needed by the inverter.

This also does not account for inverter efficiency. A modern inverter is 90% – 95% will loses a few watts during the DC to AC conversion process. So that maximum power load will consume more than 3000 watts.

But if you had a 12 x 300 watt solar array instead of 10:

A 12 x 300W solar array can give you 3480 watts an hour. Even if the solar panels never reach 300 watts, the output is still higher than the inverter requirement.

Even if your inverter is 90% efficient, there is still enough power to meet the demand. Of course you will want an inverter and PV array that is as efficient as possible for the best results.

How to Calculate Other Inverter Power Requirements

The examples assume the inverter is going to run a full 3000 watt load every hour. In that case you do need a 12 x 300W solar array to ensure ample supply.

But you won’t need that much solar power if the inverter is not going to carry a full load. In fact many users do not like to use their inverter to the limit.

Imagine you have a 2500 watt load that needs to run for four hours. How many solar panels will you need?

Inverter watt load / solar panel watt output 10% = solar panel array

In this example we will use a 300 watt solar panel:

8 x 300 watts = 2400 watts. Add 10% and you get 2640 watts.

Round that figure off to 2700 watts. 9 x 300 = 2700.

A 9 x 300 watt solar array can run a 2500W inverter load, even with energy losses factored in.

How Long Will a 3000W Inverter Run on Solar Power?

A 3000 watt inverter either runs on or off the grid. If it is on the grid, the inverter will keep running as long as there is grid power. An off grid inverter runs as long as there is a power source available.

If your home is tied to the grid, only a power outage can stop it from running. If the solar panels cannot generate the required energy, the system will use grid power.

A 3000 watt off grid inverter can run directly off solar panels. but there are limitations. The inverter can only operate during daylight and if there is enough power to carry the load.

For example, the inverter is carrying a 2400 watt load. There are five sun hours in your area. Theoretically the inverter can run solely on the PV array for five hours.

But this assumes the array generates at least 2400 watts. If the output drops below that, the system will not be able to work properly.

Even if there is sunlight, the panels must still produce enough power to maintain the power load. This is why we recommend installing a large solar array so the system can produce more power.

These problems can also be avoided if you have a battery bank. In fact, all large off grid solar systems should have one.

Modified Sine Wave Inverter:

Modified sine wave inverter, or quasi-sine wave inverter, works with most of standard appliances. Based on simple but older technology, typical modified sine wave inverter can be applied to simple power system without any delicate electronics or audio equipment. In some cases, your equipment may run hotter with modified sine wave inverter, which may also bring out potential in damaging your device in a long run.

Pure Sine Wave Inverter:

Compared to modified sine wave inverter, pure sine wave inverter produces much more efficient power and far less interference ensuring your equipment to work at its full capacity. Pure sine wave inverter is generally preferred for sensitive electronics that require more efficient power and protection, while offers great versatility than modified sine wave model.

Pure sine wave has the following advantages compared to modified sine wave in applications:

b) Pure sine wave ensures inductive loads in electronics to run quieter, faster, cooler, and smoother.

c) Pure sine wave helps in reducing humming noise or buzz when using electronics such as fluorescent lights, game consoles, TV, and fans.

d) Pure sine wave works in preventing crashes in computers, and eliminating noise, glitches, or indistinct printout in monitors.
