Solar Integration: Inverters and Grid Services Basics

Types of Inverters. There are several types of inverters that might be installed as part of a solar system. In a large-scale utility plant or mid-scale community solar project, every solar panel might be attached to a single central inverter.String inverters connect a set of panels—a string—to one inverter.That inverter converts the power produced by the entire string to AC.
