l Restart: Disconnect input and output switches in order, reconnect them after LCD and indicating lights go off.
l If there is no display on the LCD, please check both AC and DC wiring.
l If the input DC voltage is higher than start up voltage, the inverter still doesn’t work, please call local service.
l If it is intended to replace the cable or open the enclosure lid, please call our service.
l 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.
