Finding the perfect Inverter

Finding the perfect Inverter

What is an inverter?

A fundamental part of every Solar Power setup is the Inverter. It is a piece of equipment that is very important to understand.

An inverter changes DC to AC power, which is much more convenient for a variety of applications. A great example of why you might need to convert from DC to AC power is because most electronic devices use alternating current rather than direct current. Therefore, if your home or business running on solar power it would be easier for you or others that use the electricity from the building if it was converted from DC to AC

What kinds of inverters do you get?

Below is a table with a quick summary of types of inverters you get

Off-Grid Inverters

Grid-Tied Inverters


Grid or no grid connection

Grid connection required

Grid connection optional

Solar Panels optional

Solar Panels required

Solar Panels optional

Solar Batteries required

No batteries

Solar Batteries optional


Off-grid inverters

Inverters without a grid-tie feature are the cheapest inverters on the market and extremely efficient. However, they can only be used in stand-alone systems that aren't capable of being linked to the utility grid for production or consumption of electricity. However, they lack a battery charging function that means that you must use a charge controller together with your solar panels.

Grid-tied inverters

These are inverters that cannot use batteries and require electricity to function, meaning that if your electricity stops flowing, then it will switch off and whatever power your solar panels are making will stop. These systems are best used to reduce your monthly electric bill. These inverters can allow you to feed excess power back into the grid.

Hybrid Inverters

These inverters come with the best of both worlds and help facilitate electrical use regardless of whether there is a power source or not. They function as both off-grid and on-grid inverters, and they can provide feedback efficiencies if they happen to be making more power than their usage requires. The only real drawback here is that these inverters are pretty expensive; however, if this sounds like something that would be useful to you then it might worth your while regardless since you're still contributing to energy conservation regardless!

What do we recommend?

If you can feedback into the grid, then we suggest getting a Hybrid Inverter. Otherwise, an off-grid inverter will more than satisfy your needs for a power backup system or solar system.
