Check the battery system regularly. Contact your support if any anomaly detected.
6.2 Fault checklist
Fault
No voltage output when power on,
and the key light is not on
No voltage output when power on,
but the key light is on
Inverter won't start
Inverter CAN communication fails
Battery shutdown during charging
and discharging
Battery module overcurrent
protection
Battery module charging and
discharging over-temperature
protection
Cause
1. Press the key for less than 3s
2. Battery module failure
1. The battery cannot be started due
to external failure
2. Battery module failure
3. Control module fuse blown
1.The battery voltage is too low or
the SOC is lower than the shutdown
protection value
2.Battery module failure
1. Inverter manufacturer's parameter
setting without setting in PowerLite
APP;
2. Inverter battery type selection
error
3. Terminal resistance is not
installed on COM1 port of control
module
4. Inverter communication line pin
connection error
1. The charging and discharging
power is too large, and the battery is
protected from excessive power
2. Battery module failure
The charging and discharging
power is too large, and the battery is
protected from excessive power
1. The product installation
environment is too high
2. The product has been running at
rated power for too long
3. The internal fan of the battery
module works abnormally

Solution
1.Please try restarting the battery,
Press the key for more than 3s
2.Please contact the supplier for
repair or replace the battery module
1.Check the external wiring circuit,
or disconnect the external wiring
and try to power on again
2. If it cannot be started after the
external wiring is disconnected,
check or replace the battery pack
3. Check whether the fuse in the
control module is connected, if not,
please replace a new fuse.
1.Charge the battery after starting
the inverter from the grid or PV
2.Check the external wiring circuit,
or disconnect the external wiring
and try to power on again
3.Please contact the supplier for
more information
1.Log in to the PowerLite APP to
set PCS setting
2.Select the corresponding battery
type on the inverter
3.COM1 install terminal resistor
4.Check whether the
communication pin definitions of
inverter and battery are consistent
5.Please contact the supplier for
more information
1.Reduce the charging and
discharging power of the inverter;
2.Please try restarting the battery
3.Log in to the PowerLite APP to
view the fault information and
contact the supplier
1. Reduce the charging and
discharging power of the inverter;
2. Overcurrent fault can be
recovered automatically. If the fault
is triggered three times in
succession, it will be locked and the
system needs to be restarted
3.Log in to the PowerLite APP to
view the fault information and
contact the supplier
1. Check whether the ambient
temperature exceeds the maximum
allowable temperature range and
whether the battery module
installation position is well
ventilated. If it is not ventilated or
the ambient temperature is too high,
please improve the ventilation and
heat dissipation
2. Reduce the load power of the
inverter
