AI Customer ServiceA timely alarm can be generated by monitoring the midpoint of the battery bank (i.e. by splitting the string voltage in half and comparing the two string voltage halves). The midpoint deviation will be small when the battery bank is at rest, and will increase:
When properly controlled, a high voltage situation is not possible, as the BMS disconnects all chargers well before raising the high voltage alarm. 7.4. A-SL11: Under voltage alarm To remedy this warning, recharge the battery as soon as possible. 7.5. A-SL15: Over temperature alarm
One (or more) cells are very deeply discharged or defective. Check the battery terminal voltage. If the battery terminal voltage is too low, refer to the Battery very low terminal voltage chapter on what to do next. The internal circuit board has a hardware fault. To resolve this, contact your Victron Energy dealer or distributor.
This same percentage can be applied to a 12V battery bank with a 6V midpoint. In case of a 48V battery bank consisting of 12V series connected batteries, the % influence of one battery on the midpoint is reduced by half. The midpoint alarm level can therefore be set at a lower level.
In case of a new battery bank the alarm is usually due to differences in the initial state of charge of the individual battery. If the deviation increases to more than 3% you should stop charging the battery bank and charge the individual batteries or cells separately.
In case of series/parallel connection, disconnect the midpoint parallel connection wiring and measure the individual midpoint voltages during discharging to isolate faulty batteries or cells. Charge and then test all batteries or cells individually. 9.7. The Battery Balancer A consideration can be made to add a Battery Balancer to the system.
