Cause Troubleshooting Suggestions
2031 Phase Wire
Short-Circuited
to PE
Major Cause ID=1
The impedance of the
output phase wire to PE is
low or the output phase
wire is short-circuited to
PE.
Check the impedance of the
output phase wire to PE, locate
the position with lower
impedance, and rectify the
fault.
2032 Grid Loss Major Cause ID=1
1. The power grid
experiences an outage.
2. The AC circuit is
disconnected or the AC
switch is
o.
1. The alarm is automatically
cleared after the power grid
is restored.
2. Check whether the AC
circuit is disconnected or
the AC switch is
o.
2033 Grid
Undervoltage
Major Cause ID=1
The grid voltage is below
the lower threshold or the
undervoltage duration has
exceeded the time that
triggers LVRT.
1. If the alarm occurs
occasionally, the power grid
may be abnormal
temporarily. The inverter
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 not, contact the
local power operator. If yes,
modify the grid
undervoltage protection
threshold through the
mobile app, SmartLogger,
or network management
system (NMS) 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.
