8- Problems and solutions
When a defect occurs, the red indicator light turns on. Below there is the exhaustive list of the
defects which could happen. If the defect persists after having tried the following proposed solutions,
please contact your supplier.
Erreur
Solution
-
DC bus voltage exceeds the upper threshold
-
DC bus voltage falls below the lower threshold
-
DC bust voltage soft-start is time-out
-
Temps de démarrage en douceur onduleur trop
long
-
Inverter soft-start is time-out
-
An Inverter overcurrent event is detected
-
An relay failure event is detected
-
DC component in the output current exceeds the
upper threshold
-
Composant DC onduleur
dépasse plage
autorisée
-
Over-current on PV input is detected
-
Inverter DC component exceeds the allowable
range
1.
Disconnect AC circuit breaker first. Then,
disconnect DC circuit breaker.
2.
Until LCD screen completely shuts down, turn
on DC breaker first. It will show “No Utility”
in
LCD screen. Then, turn on AC breaker. After
300 seconds, the system will automatically
connect to the grid.
-
Over-heating
1.
The
internal temperature is higher than specified
temperature.
2.
Leave inverter to be cooled to room temperature.
-
PV input voltage exceeds the upper threshold
1.
Check if the open circuit voltage of PV modules is
higher than 500VDC.
2.
If PV open circuit voltage is
less than 500VDC,
please contact your installer
- Auxiliary power failed
1. Turn off the inverter
2. Then, restart the inverter.
-
Leakage current exceeds the allowable range
1. The ground voltage is too high.
2. Please disconnect AC breaker first and then DC
breaker. Check if grounding is connected
properly after LCD screen completely shuts
down.
3.
If grounding is corre
ctly connected, turn on DC
breaker. After it displays “No Utility” in LCD
screen, turn on AC breaker. After 300 seconds,
the system will automatically connect to the grid.
