Warning:
High ground I
Explanation:
The GFCI (Ground Fault Current Interrupter) is active due to a fault current from live parts to the
earth. The inverter will shut down.
Action:
Open the circuit breaker, and then disconnect the DC-plugs from the inverter for 5 minutes. After 5
minutes reconnect DC-plugs and close AC breaker.
If the problem persists, call service.
Warning:
Please Initiate
Explanation:
The inverter has not been initiated for the first time in the factory.
Action:
Call service
Warning:
GFCI Damaged
Explanation:
The GFCI-protection unit is damaged.
Action:
Call service
Warning:
Sensor Damaged
Explanation:
The DC current sensor in the inverter is damaged.
Action:
Call service
Warning:
SCI damaged
Explanation:
The communication between the two micro controllers in the inverter has failed.
Action:
Call service
Warning:
High DC INJ
Explanation:
Normally the inverter injects AC-current into the public grid. When the warning “high DC INJ” is on,
for some reason the injection of DC-current into the grid is higher then acceptable, and the inverter
shuts down.
Action:
Open the circuit breaker, and then disconnect the DC-plugs from the inverter for 5 minutes. After 5
minutes reconnect DC-plugs and close AC breaker.
If the problem persists, call service.
Warning:
High Bus Voltage
Explanation:
The internal BUS-voltage is too high.
Action:
Open the circuit breaker, and then disconnect the DC-plugs from the inverter for 5 minutes. After 5
minutes reconnect only the DC-plugs (do not close the circuit-breaker!).
Is the warning “High Bus Voltage” visible on the display?
Yes
the voltage from the solar panels is too high, or there is an internal failure (Call service).
No
close the circuit-breaker and wait for the inverter to reconnect to the grid. If the “High Bus
Voltage”-warning comes back again after reconnecting to the grid, there is probably something wrong
with the grid. (Call an electrician).
Warning:
Relay Damaged
Explanation:
The internal relays used for connecting the inverter to the grid are damaged.
Action:
Open the circuit breaker.
Call service
Warning:
Auto test failed
Explanation:
The self-test of the inverter has failed. There is an internal failure.
Action:
Open the circuit breaker, and then disconnect the DC-plugs from the inverter for 5 minutes. After 5
minutes reconnect DC-plugs and close AC breaker.
If the problem persists, call service.
Warning:
2.5V Ref Fault
Explanation:
The internal voltage reference of the inverter is defect.
Action:
Call service.
Warning:
There is nothing visible on the display.
Explanation:
Action:
The display power is coming from the solar panels.
Check if the DC-plugs are firmly connected to the inverter. If there is sufficient daylight and the LCD
does not give any indication / value
call service.
