ID01
GridOVP
The power grid voltage is too high
If the alarm occurs occasionally, the possible
cause is that the electric grid is abnormal
occasionally. ME3000SP automatically returns
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 no, contact SOFAR
technical support. If yes, check the AC circuit
breaker and AC wiring of the ME3000SP.
If the grid voltage/frequency is within the
acceptable range and AC wiring is correct,
while the alarm occurs repeatedly, contact
SOFAR 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.
If you confirm that AC wiring is correct & grid
voltage/frequency is within acceptable range,
the alarm still occurs repeatedly, try to change
country code to 22. Then restart ME3000SP to
see if problem is solved.
