Severity
Possible Cause
Troubleshooting Suggestion
2032
Grid
Failure
Major
Cause ID = 1
The power grid
experiences an outage.
The AC circuit is
disconnected or the AC
switch is off.
1.
Check the AC voltage.
2.
Check whether the AC circuit is
disconnected or whether the AC
switch is off.
2033
Grid
Undervolt
age
Major
Cause ID = 1
The power grid voltage is
below the lower threshold or
the undervoltage duration
exceeds the value specified by
LVRT.
1.
If the alarm occurs occasionally,
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
mobile phone app, SmartLogger,
or NMS to modify the grid
undervoltage protection
threshold with the consent of the
local power operator.
3.
If the fault persists for a long
time, check the connection
between the AC switch and the
output power cable.
2034
Grid
Overvolta
ge
Major
Cause ID = 1
The power grid voltage is
beyond the upper threshold or
the overvoltage duration
exceeds the value specified by
HVRT.
1.
If the alarm occurs occasionally,
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
mobile phone app, SmartLogger,
or NMS to modify the grid
overvoltage protection threshold
with the consent of the local
power operator.
3.
Check whether the peak voltage
of the power grid is too high. If
the fault persists and cannot be
rectified for a long time, contact
the power operator.
