Of the top 26 most efficient solar inverters 20 are SMA inverters. Only 26 individual solar inverters are rated at either 98 or 98.5% efficiency (which is the highest efficiency for inverters). SMA has been around since 1981 and seems to be the clear leader in manufacturing top-of-the-line inverters for solar applications.
The range of solar inverter efficiency isn’t that large as three quarters of the solar inverters compared have efficiencies greater than 95%. Most consumers don’t need to worry about the efficiency of the inverter as the differences are quite small. But if you’re looking for the best you can get, you’ll want to look to SMA first.
