There are several ways to check if your inverter is working correctly:

• Display or LED indicators → A green or blue light usually means everything is functioning normally. A red light or error code may indicate a problem.
• Monitoring app → Check whether the energy production matches previous periods and weather conditions.
• Energy production → A sudden or gradual drop in yield may indicate a problem with the inverter.

If you receive an error message or notice abnormal energy production, it may be necessary to have your inverter checked or replaced.
