Grid
Undervoltage
Major
Cause ID = 1
The grid voltage is below
the lower threshold or the
low voltage duration has
lasted for more than the
value specified by LVRT.
1. If the alarm occurs
accidentally, the
power grid may be
abnormal temporarily.
The SUN2000
automatically recovers
after detecting that
the power grid
becomes normal.
2. If the alarm occurs
frequently, check
whether the power
grid voltage is within
the acceptable range.
If no, contact the local
power operator. If yes,
modify the power grid
undervoltage
protection threshold
with the consent of
the local power
operator.
3. If the fault persists for
a long time, check the
AC circuit breaker and
AC output power
cable.
2034
Grid
Overvoltage
Major
Cause ID = 1
The grid voltage exceeds
the higher threshold or the
high voltage duration has
lasted for more than the
value specified by HVRT.
1. Check whether the
grid connection
voltage exceeds the
upper threshold. If
yes, contact the local
power operator.
2. If you have confirmed
that the grid
connection voltage
exceeds the upper
threshold and
obtained the consent
of the local power
operator, modify the
overvoltage
protection threshold.
3. Check that the peak
grid voltage does not
exceed the upper
threshold.
