Characteristics of a Good Solar Inverter

The information in the above section can help you determine which type of inverter is best for you. Whichever inverter applies in your case, you will find the following to be reasonable indications of whether an inverter is of good quality or not.

1. Relevant Standard Bodies Approve it

General standards bodies in different countries test the quality of products to ensure they meet acceptable quality thresholds.

Find out the standard premium body in your jurisdiction and check if it has approved the inverter. It may be a general standards organization or a body that deals explicitly with energy products.

It is advisable to research the manufacturing company to see if it has a track record for quality. You can find out more about the manufacturer by looking at customer reviews online. If they have overwhelmingly negative reviews, you are unlikely to enjoy the product.


2. Your Solar Inverter Should be of the Correct Size

Ensure the inverter you buy can comfortably handle the peak production of your solar panels. Your solar panels have a kilowatts rating, and your inverter has it too; ensure the two ratings match.

You probably know that solar panels rarely reach their peak performance, which may tempt you to go for a smaller inverter. Avoid this temptation because you don’t know when the panel will produce optimally, and you aren’t always sure how much less it will produce.

This means that you can’t accurately know how much capacity to reduce from the inverter. To avoid these problems, buy an inverter with the same rating as your solar panels’ output.
