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 AC switch is ON.
Cause ID = 31/32/33
Check the impedance of output phase wire A
(cause ID = 31)/B (cause ID = 32)/C (cause
ID = 33) to the PE cable and locate the
position with lower impedance and resolve the
issue.
