Individual models of inverters are designed specifically for certain types of solar installations: residential vs. utility-scale, 60 cell vs. 72 cell solar panels, system level or module level power economics.

There are three primary inverter types: string inverters, power optimizers paired with string inverters and microinverters. Inverters may come with additional features and capabilities beyond their standard method of operation.

Organizations like the International Electrotechnical Commission (IEC) and Underwriters Laboratories (UL) create national and international standards for inverter systems to ensure any products on the market meet certain specifications for safety and reliability reasons.
