Suggestion
1. Turn off the inverter AC
output switch, inverter DC
input switch, and battery
DC switch, and wait for 5
minutes.
2. Check that the
communications cable
(terminal) is correctly
connected to [Battery-1/2
battery expansion
module-1/2/3]. Method for
checking terminal
connections: Connect
battery expansion modules
to the power control
module one by one. If all
battery expansion modules
work properly, the bottom
terminals of one or more
battery expansion modules
are faulty. In this case,
exchange the positions of
the lowest normal battery
expansion module and the
battery expansion module
at the bottom. If none of
the battery expansion
modules works properly,
replace the power control
module. Otherwise, replace
the faulty battery
expansion module/
modules.
3. After checking that the
cables are correctly
connected, turn on the
battery DC switch, inverter
AC output switch, and
inverter DC input switch in
sequence.
4. If the alarm persists,
contact the vendor or
technical support.
