Unable to charge and discharge with red LED on. The temperature is 0~50 degree.
Use charger to charge, not possible. Use load to discharge, not possible.
g) Under permanent protection. The single cell voltage has been higher than 4.2
or lower than 1.5 or temperature higher than 80 degree.
Solution:
Switch off the module and contact your local distributor for repair.

Unable to charge and discharge without red LED on. The temperature is 0~50 de
-
gree. Use charger to charge, not possible. Use load to discharge, not possible.
h) Fuse broken.
Solution:
Switch off the module and contact your local distributor for repair.

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 commu
-
nication between battery system and inverter whether established or not; 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

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
