Technical Parameters & Block Diagram; Technical Parameters - GE GEP12-L-10 User Manual

Type of fault
Relay-check Failure
DCI High
Inverter 1. Disconnect the DC connector.
EEPROM R/W Failure
2. Reconnect the DC connector.
Failure
SPI Failure
3. If the problem still exists, please call the local service office.
DC Bus High
GFCI Failure
1. Disconnect the DC switch, take off DC connector, measure the voltage
of PV string.
2. Plug in DC connector, and reconnect DC switch.
Others
No display 3.If the voltage is less than 70 V, please check the PV string configura-
tion.
4. If the voltage is higher than 180V and still no display please contact
local service office.
When sunlight is insuffcient, the PV inverter may continuously start and shut down due
to insufficient power generation by the PV panel, this will not damage the inverter. If the
problem still exists, please call the local service office.
Earth Fault Alarm
Inverters sold in Australia and New Zealand will also alarm as following when Isolation Fail occurs.
1. The buzzer in the inverter will sound for 1minute. If the problem persists, the buzzer willsound
every 30 min.
2. After adding the inverter to Power Sight, the alarm information will be emailed to the customers
via Power Sight.
