4 FAQs about String Inverter vs Micro Inverter

Should I use a microinverter or string inverter for my solar system?

A common decision you'll have to make when designing your custom solar system is whether to use microinverters or string inverters. The basic function of an inverter is to change the Direct Current (DC) power generated by your solar panels to Alternating Current (AC) that can be used to power your home.

What is the difference between a microinverter and a string inverter?

Microinverters are small devices mounted beneath each solar panel. They convert DC electricity to AC at the panel level. String inverters are larger, centralised units. They convert DC to AC for a whole group of panels at once. Microinverters allow each panel to work on its own. String inverters make all the panels work together as one unit.

Do I need a string inverter?

No, if you have a string inverter, you likely only need one inverter for the whole system. Also, some microinverters allow you to hook up multiple panels to each microinverter you have. What is a common problem for inverters?

Are microinverters the same as optimized string inverters?

Microinverters and optimized string inverters provide many of the same benefits, but they're not the same things. Here are the biggest differences: Microinverters convert DC energy into AC energy right at the panel site (typically on the roof).
