1. If it happens occasionally, it belongs
to the short-time abnormality of the
power grid, the inverter will return to
normal operation after detecting that
the power grid is normal, and there is
no need to deal with it.
2. If it cannot be recovered for a long
time, please confirm:
whether the AC circuit breaker is
disconnected
whether the AC terminal or fuse is in
good contact
whether the power supply line is normal
If this fault is still being shown, contact
the service.
1. If it happens occasionally, it belongs to
the short-time abnormality of the
power grid, the inverter will return to
normal operation after detecting the
normal power grid, and there is no
need to deal with it.
2. In case of frequent occurrence but
automatic recovery, please confirm if
the grid voltage is outside the
permissible range due to local grid
conditions, try to modify the values of
the monitored operational limits after
informing the electric utility company
first.
3. If it cannot be recovered for a long
time, please confirm:
· whether the AC circuit breaker is
disconnected
· whether the AC terminal is in good
connection
·
whether the power supply line is normal
·
whether the AC cable wiring (such as wire
length and wire diameter) complies with
the user manual guidance
·
whether the safety regulation settings are
normal
