What is a Solar Panel Inverter?

A solar panel inverter is the device that changes the energy produced by your panels into a form your appliances can use. Without an inverter, you could not use your solar power to run home appliances and connect to the electricity grid. Go here solar inverter generator | ShopSolarKits.com

How It Works

The sunlight that shines on the silicon of each solar panel creates a charge in the cells. That charge then generates direct current (DC) electricity. The inverter transforms this DC to alternating current (AC) to allow your appliances to use that electricity.

What to Look For

A good solar inverter converts direct current into alternating current, the standard form of electricity used by most appliances at home. It also acts as a safety net to keep your system running safely if something goes wrong.

String Inverters

The most common type of inverter, a string inverter consists of multiple panels that are arranged into groups or strings and linked together. Each panel in the string sends DC power to the inverter, and the inverter transforms that into AC.

However, a string inverter can only generate the maximum power it can handle if all of its panels are producing, and if one or more of those panels stops or slows down, then the rest of the string’s output is limited by that one weak panel.


Microinverters are the most expensive of all inverter types, but they last longer than string inverters and are more reliable overall. They also allow you to monitor each panel’s performance, and some also offer an inverter efficiency rating to help you understand how efficiently your solar panels are performing.
