Inverter
The device that converts a solar array's DC electricity into the AC power your home and the grid use — the system's most failure-prone component.
The inverter is the brain of a solar system, turning the direct current panels produce into the alternating current your appliances and the utility grid require. It also handles safety shutdown, grid synchronization, and (in many systems) production monitoring.
Inverters come in three flavors: a single central string inverter, panel-level microinverters, or a string inverter with DC optimizers. Because of the electronics involved, the inverter is typically the first major component to need replacement, often around 10–15 years.
