PVUVP
The input voltage is
too low.
Check whether too few PV modules
have been connected in series per
string: therefore, the voltage (Vmp) of
the PV 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. The inverter automatically
returns to its normal operating state
after the string has been corrected.
ID09
PvOVP
The input voltage is
too high.
Check whether too many PV modules
have been connected in series per
string: the voltage (Voc) of the PV
string is therefore higher than the
maximum input voltage of the
inverter. In this case, adjust the
number of photovoltaic modules
mounted in series to decrease the
voltage of the PV string, so that it falls
within the input voltage range of the
inverter. The inverter automatically
returns to its normal operating state
after the string has been corrected.

IpvUnbalance
The input current is
not balanced.
Check the configuration of the input
mode (parallel mode / independent
mode) of the inverter, as indicated in
Section 6.3 (C).
“6 Input mode” of this user manual; if
this setting is incorrect, change it
according to Section 6.3 (A) “10.
Configuration of the input mode” of
this manual.

breaker.
If the fault occurs occasionally, the
probable cause is that the external
circuits have temporary faults.
The inverter automatically returns to
its normal operating state after the
error has been fixed.
If the fault repeats itself often and
lasts for a long time, check whether
the insulation resistance between the
PV string and the ground is too low,
then check the insulation conditions
of the PV cables.

HwBoostOCP
The input current is
too high and has

protection to be
Check if the input current is higher
than the maximum input current
allowed by the inverter, then check
the input wiring; if both are correct,
