2035 Grid Voltage
Imbalance
Major Cause ID = 1
The dierence
between grid phase
voltages exceeds
the upper
threshold.
1. If the alarm occurs accidentally,
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 no, contact the local
power operator.
3. If the fault persists for a long
time, check the connection of
the AC output power cables.
4. If the AC output power cables
are correctly connected, but the
alarm persists and
aects the
energy yield of the PV plant,
contact the local power
operator.
2036 Grid
Overfrequency
Major Cause ID = 1
Power grid
exception: The
actual grid
frequency is higher
than the
requirement of the
local power grid
standard.
1. If the alarm occurs accidentally,
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 grid
frequency 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 underfrequency
protection threshold with the
consent of the local power
operator.
