i) High voltage protection.
Cell voltage higher than 4V or module voltage higher than 55.5V.
Solution: Battery system requires properly established communication
with inverter and correctly settings on inverter to run safely. Check the
setting of the inverter or charger, the charge voltage shall be 53.2~52.5Vdc;
Check the communication between battery system and inverter; Check the
ADD switch on battery module whether is set correctly or not;
Under this condition, the BMS remains functional without damage. Just
leave the module switched OFF and wait for the battery voltage drop down
naturally(15mins) then restart. If then no alarm comes out, this means the
module is ready for work
6） Buzzer rings and ALM solid red
j) Reverse connection of cables.
Solution: Power off all battery and inverters. Disconnect breaker. Check the
cable connection and disconnect all power cables. Check the power port
damaged or not. Then try turn on the single module, without any cable
connected. If no alarm, then it is reverse connection of cables. Switch off
the module and contact your local distributor.
k) MOSFAIL.
Solution: Power off all battery and inverters. Disconnect breaker. Check the
cable connection and disconnect all power cables. Check the power port
damaged or not. Check the setting of inverter or charger, check the
communication between inverter and battery system.
Try turn on the single module, without any cable connected. If still buzzer
rings. Then switch off the module and contact your local distributor.
7） After switch On, the module turns on directly
l) BMS failure.
Solution：Switch off the module and contact your local distributor.
