The inverter is in the grid overvoltage de-
rating state. This setting is related to the
grid high voltage alarm. Please check the
grid voltage and confirm the Level 1 over-
voltage protection value setting with cus-
tomer service.
1. The inverter is shut down due to the
shutdown command. Contact customer
service to try restarting the inverter and
check whether the inverter is restored.
2. Unplug the communication module and
confirm whether the alarm can be cleared.
If the alarm can be clear, contact customer
service to replace the communication
module.
Solution
1. If it happens occasionally, the inverter
can recover automatically, no processing is
required.
2. If it occurs frequently or continuously,
please check whether the installation site is
exposed to direct sunlight, whether the
ventilation is good, and whether the ambi-
ent temperature is too high (such as in-
stalled on a parapet). If the ambient tem-
perature is lower than 45 degrees and the
ventilation is good, please contact the cus-
tomer service center for further check.
1. Measure the open-circuit voltage of the
actual configuration (the influence of the
local minimum temperature should be
considered when calculating the maximum
open-circuit voltage), and compare it with
the maximum full-load working voltage of
