overcurrent of A
phase current
When the inverter is shut
down, the inverter is
operated automatically
after
the fault is
eliminated
1.Check whether the
power grid wiring is short
circuited, check whether
there is a interference
source beside the inverter,
if not, please restart the
inverter .
2.Check
whether the
voltage waveform of the
power grid is abnormal.

When the inverter is shut
down, the inverter is
operated automatically
after
the fault is
eliminated
1.Check whether the
power grid connection is
normal.
2.If the fault exists all the
time, restart the inverter .
3.If the restart of the
inverter is invalid, please
contact the Hefei Jntech
gathering
customer
service center.
