Technical Parameters - Goodwe NS Series User Manual

Type of fault
Relay-Check Failure
DCI Injection High
1. Turn off DC switch of the inverter.
Inverter
EEPROM R/W Failure
2. Wait till the inverter's LCD light is off.
Failure
3. Turn on DC switch and make sure it is connected.
SPI Failure
4. If the problem still exists, contact local service office for help.
DC BUS High
GFCI Failure
1. Turn off DC switch, take off DC connector, measure the voltage of PV array.
2. Plug in DC connector, and turn on DC switch.
Others
No display 3. If PV array voltage is lower than 250V , please check configuration of inverter
module.
4. If voltage is higher than 250V , please contact local office.
Note:
When sunlight is insufficient, the PV inverter may continuously start up and shut down automati-
cally due to insufficient power generation from the PV panels, which would not lead to inverter
damage.
