1. Check the
wiring of the
water pump and
whether
the
water pump can

Bus voltage
undervoltage
When the
inverter
stops,
the
system can
start
itself
after the
shutdown
state
disappears.
The grid
voltage is too
low, or the
array voltage
is too low, or
the hardware
fails.
Disconnect the
power grid and
photovoltaic input
switch to ensure
no voltage input
to the inverter.
Check the power
grid voltage and
photovoltaic
voltage
with a
multimeter
respectively.
