protection points after obtaining approval
from the local electrical grid operator.

GFCI

Charge Leakage Fault

Check for inverter and wiring.

ID006

OVRT fault

OVRT function is faulty

If the alarm occurs occasionally, the

possible cause is that the electric grid is
abnormal occasionally. Inverter will
automatically return to normal operating

status when the electric grid’s back to
normal.

If the alarm occurs frequently, check

whether the grid voltage/frequency is
within the acceptable range. If yes, please
check the AC circuit breaker and AC wiring

of the inverter.
If the grid voltage/frequency is NOT within

the acceptable range and AC wiring is
correct, but the alarm occurs repeatedly,

contact technical support to change the
grid over-voltage, under-voltage,

over-frequency, under-frequency
protection points after obtaining approval

from the local electrical grid operator.
