"In my previous role, we encountered an unexpected inverter failure in a solar panel system. I first checked the system's error codes and performed a visual inspection to identify any obvious issues. After isolating the problem to a faulty component, I replaced it and tested the system to ensure it was functioning correctly. This quick and effective response minimized downtime and maintained the system's efficiency."
