Do you have an off-grid wind or solar power system in your home? Then you’ll certainly need the best off-grid inverter.
“Really! Can’t I just use that power from the wind or solar power system directly?”
The answer is simple: No, you can’t!
This is because your off-grid power system generates Direct Current (DC) power. And you can’t power your appliances with DC power.
Instead, appliances and electronic use alternating current (AC). Which is why you need an off grid inverter. Since it converts the generated direct current (DC) power into alternating current (AC) power.
But, how do you choose the bestter off grid inverters in the market? Well, that’s is one of the many reasons we’re writing this review.

Things to Consider When Buying A Best Off Grid Inverter
You should not rush and buy any off-grid power inverter that comes your way. This is because there are many inverter models in the market at the moment. And you may end up selecting an inverter that doesn’t meet all your needs.
So, before you buy an inverter, there are certain factors you should consider. Some of these factors include;
Before you invest your money on a power inverter, it’s important to understand its power rating. This is because different inverters have different power ratings. This usually ranges from 50 to 50000 Watts. This includes looking at the requirements of the inverter.
Small appliances consume less power while larger power tools more power. Thus, the right power inverter should produce more power than what appliances need.
For instance, if they need 4000W, choose an inverter that delivers a continuous load of 5000W.
Additionally, you should look at the surge of the inverter. Surge load is the largest load that your unit can handle for a certain period.
Efficiency is another factor you should consider when purchasing a power inverter. For instance, choose an inverter that doesn’t increase or consume so much power. This will help you to avoid energy and power loss.
Most inverters aren’t 100 percent efficient. This means that they don’t convert all the DC power into AC power.
The device may lose some power during the conversion process. This can be a problem. Especially if the inverter loses too much power.
So, choose an inverter with a peak conversion efficiency of about 94%.
Pure or Modified Sine Wave
There are various types of inverters. With the two most popular ones being; pure sine wave and modified sine wave inverters. So, when buying an inverter, you should be able to differentiate between these 2 types.
So, what is the difference between a modified sine wave and a pure sine wave inverter? Is that your question too?
Well, Modified sine inverters are ideal for small applications and older appliances. While pure sine wave power inverters generate more energy. You can use this energy in larger off-grid systems or for modern appliances.
Off grid inverters are very susceptible to extreme cold and heat. So, when purchasing an inverter, look at its temperature range. This will enable you to determine the largest/ smallest temperature it can handle.
Additionally, we recommend that you buy an inverter with an inbuilt cooling fan. An inbuilt fan keeps the unit cool for long, thus extending its useful life.
Look for an inverter with various inbuilt safety features. Some of these features include; high heat protection, fuses and low battery shutoffs. Also, it’s important to select a device with over-current and overload protection. This will help to protect the inverters as well as your appliances.
What Are The Different Types Of Off-Grid Power Inverters
Off-grid inverters are a bit different from grid tier inverters. Off-grid inverters need an established solar power system. Yet you don’t have a connection to the local power grid.
Their main difference is that an off-grid inverter requires an energy bank to operate. While the grid tier doesn’t. In a solar power system, solar panels deliver DC energy. This energy is then stored in the energy bank.
To use the generated DC energy on your appliances or lights, DC energy has to go through an off-grid inverter. At the inverter, it’s converted into AC energy. You can now use to power your appliances.
With that in mind, let’s now get into the 3 different types of off-grid inverters. They include; pure sine wave, modified sine wave and Hybrid Inverters.
Pure Sine Wave inverters
As we stated earlier, an inverter changes DC to AC. But it doesn’t produce or store electricity. The device includes a gradual peak. The peak transforms electricity from fuel cells and batteries to AC electricity.
Most modern appliances need true sine wave for the best functionality. And this is where the pure sine wave inverter comes in. this type of inverter works well with most types of off grid power systems.
These inverters can power small appliances. But they’re ideal for large power needs. This is because they have a high power output.
You can find these types of inverters with different sizes and power options. This allows you to choose the inverter that works well for you.
Modified Sine Wave Inverter
The other type of off-grid inverter is the modified sine wave unit. These inverters are also great options, especially because they are quite affordable. You can use them as some sort of a backup generator.
But, these inverters have low power output. Also, they don’t work well with modern appliances. But you can use them to power old TVs, brush motors and basic lights in an old cabin.
Hybrid inverters combine battery power with solar energy to supply electricity. These types of inverter perform a lot of tasks and they’re generally very heavy. In simpler terms, it’s a battery inverter and a solar inverter merged into one unit.
This inverter will enable you to enjoy features of both solar and battery inverters. Also, you can either use this device if you’re living off or on the power grid.
