Is your solar inverter losing efficiency? in California

Your inverter converts DC power from your panels into usable AC electricity. When it degrades or malfunctions, your entire system's output drops — sometimes by 10–25%. Here's how to spot inverter issues early and what to do about them.

Typical loss: 525%

Self-check tip:

Check your inverter display for error codes or red/amber warning lights. Compare current output to the inverter's rated capacity.
