power. If the resistance of the AC cable is too high, it
will cause a huge increase in the AC voltage, which
may lead to a disconnection of the inverter from the
electrical grid. The relationship between power loss in AC cable and wire length,
wire cross sectional area is shown in the following figure：

whether the grid voltage/frequency is within the
acceptable range. If no, contact technical
support. If yes, check the AC circuit breaker and
AC wiring of the inverter.
If the grid voltage/frequency is within the
acceptable range and AC wiring is correct, while
the alarm occurs repeatedly, contact technical
support to change the grid over-voltage,
under-voltage, over frequency, under-frequency
protection points after obtaining approval from
the local electrical grid operator.
Check whether too few PV modules are
series connected in a PV string, thus the
voltage(Vmp) of the PV string is lower than the
minimum operating voltage of inverter. If yes,
adjust the number of series connected PV
modules to increase the voltage of the PV string
to fit the input voltage range of inverter. inverter
automatically returns to normal operating status
after correct adjustments.
Check whether too many PV modules are
series connected in a PV string, thus the
voltage(Voc) of the PV string is higher than the
maximum input voltage of inverter. If yes, adjust
the number of series connected PV modules to
decrease the voltage of the PV string to fit the
input voltage range of inverter. inverter
automatically returns to normal operating status
after correct adjustments.

If the fault occurs occasionally, the possible
cause is that the external circuits are abnormal
occasionally. inverter automatically returns to
normal operating status after the fault is rectified.
If the fault occurs frequently and lasts a long
time, check whether the insulation resistance
between the PV array and earth(ground) is too
low, then check the insulation conditions of PV
cable.
Check whether the input current is higher
than the maximum input current of inverters,
then check the input wiring, if both are correct,
