setting of the inverter or charger, the charge voltage should be 56~56.8
VDC; Check whether the communication between battery system and
inverter is established; Check whether the ADD switch on battery module
is set correctly.
Under this condition, the BMS remains functional without damage. Just
leave the module switched OFF and wait for the battery voltage to drop
down naturally (15 minutes) and then restart. If then no alarm comes out,
this means the module is ready for work.
j) Reverse connection of cables.
Solution: Power off all batteries and inverters. Disconnect breaker. Check
the cable connection and disconnect all power cables. Check that the
power port is damaged. Then try to turn on the single module without any
cable connected. If there is no alarm, then it is reverse connection of
cables. Switch off the module and contact your local distributor.
k) MOSFAIL.
Solution: Power off all batteries and inverters. Disconnect breaker. Check
the cable connection and disconnect all power cables. Check that the
power port damaged. Check the setting of inverter or charger. Check the
communication between inverter and battery system.
Try to turn on the single module without any cable connected. If the
buzzer still rings, switch off the module and contact your local distributor.
6) After switching on, the module turns on directly.
l) BMS failure.
Solution: Switch off the module and contact your local distributor.
Excluding the points above, if the faulty still cannot be located, turn off
battery and contact your local distributor.
