Internal fan fault
Please contact with after-sales if error remains the same after
several reset.
Restart: Disconnect input and output switches in order, reconnect them after LCD and indicating lights go off.
If there is no display on the LCD, please check both AC and DC wiring.
If the input DC voltage is higher than start up voltage, the inverter still doesn’t work, please call local service.
If it is intended to replace the cable or open the enclosure lid, please call our service.
Under the low light conditions, the inverter may continuously start up and shut down. It is due to insufficient
power generated to operate the control circuits.
