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.

ID001
Grid OVP
The grid voltage is too
high
If the alarm occurs occasionally, the
possible cause is that the electric grid is
abnormal occasionally. Inverter will
automatically return 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 yes, please check
the AC circuit breaker and AC wiring of the
inverter.
If the grid voltage/frequency is NOT within
the acceptable range and AC wiring is
correct, but 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.
