Recovery method C: Auto-restart after waiting 10 sec. But enter recovery method D when error four times (show d-XX error code.) IV. Recovery method D: Turn on solar power conditioner by hand after repaired.
Check The solar power conditioner is in normal status. Action Wait until the utility grid recovers. The solar power conditioner will restart automatically. Cause AC breaker is shut down. Case.2 Check Check the status of the AC breaker. Action Turn on the AC beaker. The utility grid is received and the solar power conditioner will restart automatically. Cause Voltage of the utility grid falls due to the electric supply status of the power company.
Check If the error message “F-02” appears frequently after restarting the solar power conditioner, the frequency detecting circuit on the control circuit is in abnormal condition. Action Replace a new solar power conditioner. Error code F-03 Recovery method : A Description Utility frequency under setting value Protection level Less 47Hz [Parametr:46Hz / 47Hz / 48Hz] Activation time 1 sec(default value) [Parametr:1S / 1.4S / 1.8S] Case.1 Cause Power failure of the utility grid.
