Read: What Happens When UPS Battery Fails? #2 The Backup Battery Is Low On Power. Why it''s beeping: When a power outage occurs, the UPS backup battery will kick into action for a limited period.That period
AI Customer ServiceIt is actually the MASTER battery which shows up an alarm and sends it to the GX. At first we were worried about such abnormal voltages readouts on cells. After exchanges
AI Customer ServiceKeeping the battery at such a high voltage will decrease the lifetime of the battery. 6.1.4. Less capacity than expected. If the battery capacity is less than its rated capacity, these are the
AI Customer ServiceMost likely cause, first thing to check, is cell imbalance, which in itself is not a problem and normal to occur of the battery doesn''t have the option to sufficiently and often
AI Customer ServiceThe vigh voltage alarm will probably not be referring to the whole battery bank voltage but rather one or two cells in the bank. Try charging at lower current for a bit or
AI Customer ServiceCan you see the individual cell voltages? Could be that only one cell reaches the maximum allowed voltage and the BMS triggers the high voltage alarm. If that''s the case, lower the
AI Customer ServiceThe voltage of one or more cells is becoming too low and has dropped below the pre-alarm setting. Tip To remedy this warning, recharge the battery as soon as possible.
AI Customer ServiceFor weeks no issue, but now suddenly I get High Voltage warnings. I don''t know where the high voltage occurs. Battery? Where do I check this? And then what to do about it? How to limit the
AI Customer ServiceInspect the deepest discharge, minimum battery voltage and number of full discharges in the battery monitor. Total and very deep discharge voids the warranty. Is there an indication the
AI Customer ServiceOne bad cell or one bad battery can destroy a large, expensive battery bank. A short circuit or high internal leakage current in one cell for example will result in undercharge of that cell and
AI Customer ServiceThat high battery voltage alarm is actually a high cell voltage alarm, sent by the BMS. Most likely cause, first thing to check, is cell imbalance, which in itself is not a problem
AI Customer ServiceThe alarm is coming from the battery monitor (should be the Pylontech) not from the Quattro. Under advanced you can enable diagrams for the battery voltage/current,
AI Customer Servicethe problem is a high voltage alarm on the ccgx. When the soc is 100% often the battery will get in high voltage alarm (above 54V). the setup is done as discribed in the
AI Customer ServiceRevive the battery with a battery charger or charge controller featuring lithium battery activation or force charging. The battery shuts off due to undervoltage protection. The
AI Customer ServiceLeave the batteries overnight to settle, and in the morning, if one is still showing a particularly low voltage (say, <12.5V) try putting a known load across it (a spotlight or car
AI Customer ServiceWhen the local high-voltage disconnect button is pressed or the high-voltage disconnect junction on the interface board is closed, the system will report an external fault.
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
AI Customer ServiceFrom the batteries manual, it seems that this means that they are in protection mode, from the inverter manual the "battery open" says to check the battery terminals. I disconnected everything and let it rest for 30 minutes to

AI Customer ServiceThis might be quite elementary to solve, however I keep getting high voltage alarms from the Pylontech battery at times of high solar yield. What can be done to solve the problem. The
AI Customer ServiceCan you see the individual cell voltages? Could be that only one cell reaches the maximum allowed voltage and the BMS triggers the high voltage alarm. If that''s the case, lower the battery charging voltage (maybe start at 51.75V and
AI Customer ServiceWhen 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
A 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:
Immediately disable all chargers and contact the system installer to check that all chargers are properly controlled by the “charge disconnect” contact on the BMS. 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
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.
Be 100% sure that the BMS controls the charger; dangerous cell overvoltage can occur if it is not. Check this by monitoring the cell voltages using the VictronConnect app. The voltage of the fully charged cells will slowly creep up until 3.7V has been reached. At this point, the BMS will disable the charger and the cell voltages will drop again.
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.
