Best solar inverters

What are the best inverters available? Top brands of 2022 compared

If you want to maximize your solar energy system’s production, finding the best solar inverter is as important as the solar panels you choose. For an “uncomplicated” roof – one that faces south and has no gables, chimneys, or other obstructions that can cast a shadow – the best solar inverter for you may be a standard string (aka central) inverter. But, more than half of new residential solar installations are using module-level power electronics (MLPEs) – such as power optimizers and microinverters – to maximize electricity production on more complicated, less ideal rooftops.

In the world of MLPEs, you might be trying to decide between two big names, SolarEdge vs. Enphase, and with good reason: about 95 percent of quotes on EnergySage included either SolarEdge or Enphase in 2022! That said, there are many other great inverter options to consider. At the end of the day, the question of which is the best solar inverter comes down to performance, warranties, cost, and personal preference.
