The grid voltage is too high
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 ZCS 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.
ID002
The grid voltage is too low
ID003

Charge Leakage Fault
Internal faults of inverter, switch OFF inverter,
wait for 5 minutes, then switch ON inverter.
Check whether the problem is solved.
If not, please contact ZCS technical support.
