repeatedly, contact Technical Support
to change the grid overvoltage,
undervoltage, over-frequency and
under-frequency protection points
after obtaining approval from the
local grid operator.
ID05
PVUVP
The input voltage is
too low.
Check whether too few PV modules
have been connected in series in a PV
string: therefore, the voltage (Vmp) of
the photovoltaic string is lower than
the minimum operating voltage of the
inverter. In this case, adjust the
number of photovoltaic modules
connected in series to increase the
voltage of the PV string, so that it falls
within the input voltage range of the
inverter.

Check the AC grid connections, and if
they are correct, contact technical
support.

PvOVP
The input voltage is
too high.
The inverter automatically returns to
its normal operating state after
correct adjustment.
Check whether too many PV modules
have been connected in series in a PV
string: therefore, the voltage (Voc) of
the photovoltaic string is greater than
the minimum operating voltage of the
inverter. In this case, decrease the
voltage of the PV string by adjusting
the number of photovoltaic modules
mounted in series, making sure that it
falls within the input voltage range of
the inverter. The inverter
automatically returns to its normal
operating state after the correct
adjustments.
