If an Earth Fault Alarm occurs, the fault will be displayed on the LCD screen,
the red light will be on, and the fault can be found in the history of the fault.
For the machine installed with Wi-Fi/GPRS, the alarm information can be seen
on the corresponding monitoring website, and can also be received by the APP
on the mobile phone.

GridOVP
The power grid
voltage is too high
If the alarm occurs occasionally, the
possible cause is that the electric grid is
abnormal occasionally. inverter automatically
returns to normal operating status when the
electric grid’s back to normal.
If the alarm occurs frequently, check
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.

PVUVP
The input voltage is
too low
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.
ID09
PVOVP
The input voltage is
too high
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.
