ID001
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
SOFARSOLAR 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.
