The grid voltage is beyond the
acceptable range. The possible
causes are as follows:

Cause ID = 4
The grid voltage is below the
specified lower threshold.

Cause ID = 16
The grid voltage exceeds the
specified upper threshold.

Cause ID = 19
The grid voltage has
exceeded the specified upper
threshold for 10 minutes.

Cause ID = 26
The grid voltage exceeds the
specified upper threshold.

Cause ID = 28
The three phases of the
power grid differ greatly in
voltage.

Cause ID = 29
1. The power grid
experiences an outage.
2. The AC circuit is
disconnected or AC
switch is OFF.

Cause ID = 31/32/33
The impedance of the output
phase wire A (cause ID =
31)/B (cause ID = 32)/C
(cause ID = 33) to the PE
cable is low or
short-circuited.
Cause ID = 4
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 grid voltage is
within the acceptable range. If no,
contact the local power operator. If
yes, log in to the SUN2000 app,
SmartLogger, or NMS to modify
the grid overvoltage and
undervoltage protection thresholds
with the consent of the local power
operator.
3. If the fault persists for a long time,
check the AC switch and AC
output power cable.
Cause ID = 16/19/26
1. Check whether the grid-tied
voltage exceeds the upper
threshold. If yes, contact the local
power operator.
2. If you have confirmed that the
grid-tied voltage exceeds the upper
threshold and obtained the consent
of the local power operator,
modify the overvoltage and
undervoltage protection thresholds.
3. Check whether the peak grid
voltage exceeds the upper
threshold.
Cause ID = 28
1. If the exception is caused by an
external fault, the SUN2000
automatically recovers after the
fault is rectified.
2. If the alarm persists and affects the
energy yield of the power station,
contact the local power operator.
Cause ID = 29
1. Check the AC voltage.
2. Check that the AC power cable is
securely connected and that the
