We have three batteries of 104Ah 51.2V in parallel, two Multiplus 5kW and 100A 150V MPPT solar charger. The alarm comes from battery BMS. Absorption and float charge parameters in solar charger are 58.4V suggested by manufacturer. This alarm only appears when batteries are 100% SOC.
Thanks for this info, I had the same problem with a Pylontech UP2500 24V 2.8kWh battery. It would seem if the battery does not get charged from the time of production to install, (the time in my case was >14 months) the cells can become unbalanced, which shows up on the first full charge and gives a battery alarm of "high cell voltage" well below the
What can be done to solve the problem. The alarms tend to show up at voltages below the recommended charge voltage settings, ie max voltage for absorption charging 53.2V and Float 53V in accordance with the manual. I have downloaded logs for some of the alarm events, these can be found at the following link.
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
so this summer I''ve gotten several high voltage alarms (14.6v) with my pair of LiFePO4 batteries (280a EVE cells). so investigating the victron SCC profile; the full charge voltage is 14.2 (looks correct) and the float charge is 13.5 (also correct) but then I noticed a little blip in the manual (yes; I read it) that LiFePO4 has a default absorption time of 2 hours and
After setup the batteries were charged from 70% to 100% the VRM is showing an alarm of High battery voltage. Battery reading 52.29V. Victron energy website shows Max Charge Voltage for this battery as 53.2V. HELP PLEASE
As the SOC ticked over 98% the supply to the batteries did start to reduce, but not quickly enough to prevent the high volt alarm. When the high volt alarm came up I could see that the system was still pushing more than 3.5kW into the batteries. What is curious is that the alarm reports that the voltage is 52.27V, which is actually lower than

Battery Monitor [512] Automatic monitoring High battery temperature alarm: Alarm; Battery Monitor [512] Automatic monitoring Low voltage alarm: Alarm; once even a Cell Imbalance was thrown in there; According to my distributor, the battery BMS sends alarms to the GX which in turn reports them to VRM. Freedom Won insist they do not send alarms to the
batteries will trigger a high-voltage alarm when connected to a Victron GX device (Venus, Color Control or Cerbo) through the CAN bus. This scenario may happen under normal condition of
ME:"If float charging voltage of 52.5V is OK, then I guess a lower float voltage 51.0V or 52.0V might be OK for charging to less than 100%. But never >52.5V. Do you agree?" PYLONTECH: "That''s correct! Because sometimes the voltage sensors on the inverter terminals are not very accurate, the full battery voltage is around 53.2V(smaller than 54V
Kurz nach dem Start der Pad Maschine kam ein Alarm der Batterie und des MultiPlus 48/2000/25-32. Eintrag Alarmmeldung: VE-Bus System automatic Monitoring Low battery Alarm. Nach Aus- und wieder Einschalten der Batterie und des Multiplus 48/2000/25-32 lief die Anlage wieder problemlos. Auch erneutes Zubereiten von Kaffee oder Staubsaugen
These alarms can indicate that there is an internal cell imbalance in the battery. It may be useful in this situation to enable this feature, and then adjust the voltage limit down so that the batteries are able to balance charge without reaching
High voltage alarm. When enabled, the alarm will activate when the battery voltage rises above the set value for more than 10 seconds. The alarm will deactivate when the battery voltage drops below the clear value.
Inspect 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 battery has been charged with a too-high voltage? Check the maximum battery voltage and the high voltage alarms in the battery monitor.
My 2015 Acadia with 40,000 km.has a battery voltage of 12.6 when started, with the voltage rising to 15 to 15.5 after a few minutes. In summer, this voltage stays in the 15V region as I drive for perhaps up to an hour or
To remedy this warning, recharge the battery as soon as possible. 7.3. A-SL9 Over voltage alarm. The voltage of one or more cells has become too high. Immediately disable all chargers and

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:
High voltage alarm: 29V High voltage reset alarm: 28.4V One last thing: I mentioned earlier that I added 200W load and alarms went away. I always have a load of about 10W (Raspberry Pi running VRM) but the load is less than the 15W minimum that can be seen by the AC load reading in the system. A real flaw in the Victron logics if you ask me.
High voltage alarm. When enabled, the alarm will activate when the battery voltage rises above the set value for more than 10 seconds. The alarm will deactivate when
The mains charger and MPPTs are set at the default settings for AGM batteries. The BMV has the high voltage alarm threshold set at 14.7 and clearing at 14.5. I am
Hello, I have a system recently installed using third party Lithium battery with BMS accepted by CAN connection on Cerbo GX. The systetm is configured on ESS. It turns out that system send an alarm from the BMS instance with high voltage alarm (the limit is 57V) but the solar charger shows only 55.6V. However on MPPT detailed history shows on battery a max
batteries will trigger a high-voltage alarm when connected to a Victron GX device (Venus, Color Control or Cerbo) through the CAN bus. This scenario may happen under normal condition of operation when the batteries are relatively new and may be slightly out of balance. The GX device may display the message
These alarms can indicate that there is an internal cell imbalance in the battery. It may be useful in this situation to enable this feature, and then adjust the voltage limit down so that the batteries are able to balance charge without reaching over voltage internally.
The mains charger and MPPTs are set at the default settings for AGM batteries. The BMV has the high voltage alarm threshold set at 14.7 and clearing at 14.5. I am contemplating setting the threshold to the fast charge voltage of 14.9.
To remedy this warning, recharge the battery as soon as possible. 7.3. A-SL9 Over voltage alarm. The voltage of one or more cells has become too high. 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.
The alarms currently trigger just above 52V. Can 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.
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 gradually raise it to 52.5V and maybe even higher) and hope that the cells will top balance eventually. @Seb71 The warnings are currently triggering at 52.04V.
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
These alarms can indicate that there is an internal cell imbalance in the battery. It may be useful in this situation to enable this feature, and then adjust the voltage limit down so that the batteries are able to balance charge without reaching over voltage internally.
1. SUMMARY Some Pylontech US & Force L1 & L2 Series batteries will trigger a high-voltage alarm when connected to a Victron GX device (Venus, Color Control or Cerbo) through the CAN bus. This scenario may happen under normal condition of operation when the batteries are relatively new and may be slightly out of balance.
Alarm delay An alarm delay is in place to prevent the occurrence of alarms during short-term deviations that will not damage a battery. The alarm is triggered when the deviation exceeds the set alarm value for more than 5 minutes. If the deviation exceeds the set alarm value by a factor of two or more, the alarm will trigger after 10 seconds.
