automatically restart;
3、Please contact with local dealer if error remains the same
after several reset.
Isolation Fault
1.PV(+) or PV(-) earthing
2、Lightening
3、Machine failure
1..Check PV(+) and PV(-) ground impedance ， make
sure impedance is more than 2MΩ；
2、Please contact with after-sales if error remains the same
after several reset.
Current DC Offset
1.AC side incorrect wiring
2、Electricity grid abnormal
3、Machine failure
1.Disconnect the input/output switch, check the AC-side wiring
and reseat the plug to rule out bad contact.
2 、 After electricity grid returns to normal, the machine will
automatically restart;
3、Please contact with local dealer if error remains the same
after several reset.
ENS Grid F Fault
1.AC side incorrect wiring
2、Grid frequency abnormal
3、Machine failure
1.Disconnect the input/output switch, check the AC-side wiring
and reseat the plug to rule out bad contact.
2 、 After electricity grid returns to normal, the machine will
automatically restart;
3、Please contact with local dealer if error remains the same
after several reset.
ENS Grid V Fault
1.AC side incorrect wiring
2、Grid voltage abnormal
3、Machine failure
1.Disconnect the input/output switch, check the AC-side wiring
and reseat the plug to rule out bad contact.
2 、 After electricity grid returns to normal, the machine will
automatically restart;
3、Please contact with local dealer if error remains the same
after several reset.
Relay 1/2 Fault
1.Machine failure
1.Please contact with local dealer if error remains the same
after several reset.
M Grid Freq Fault
1.Electricity gridfluctuations
2.Electricity gridFrequency
out of range
3.Machine failure
1.After electricity grid returns to normal, the machine will
automatically restart;
2、Please contact with local dealer if error remains the same
after several reset.
Manual reset: disconnect the input/output switch in turn, wait until the display and LEDsdo not light up, then turn on
and off input/output switch.
 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.
