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.
