- 1
Verify DC input voltage and current from PV array at inverter terminals against nominal specifications.
- 2
Verify AC grid voltage and frequency at inverter output terminals against local grid codes and inverter specifications.
- 3
Inspect all AC, DC, and communication wiring connections at the inverter for proper termination, tightness, and absence of damage.
- 4
Access inverter's internal event log via the display or service tool to check for prior warnings or related fault codes that could provide additional context.
- 5
Perform a full power cycle (disconnect AC, then DC; wait 5 minutes; reconnect DC, then AC) to force a complete system re-initialization.
