I am getting spurious battery high voltage alarms. The max battery charging voltage is set to 57.6 V but I get alarms/notifications at less than 57 V. I cannot find any way to turn off these spurious alarms/notifications. Any ideas?

Well it seems I have misunderstood how DVCC works. Today I have enough PV power to get to full charge and I noticed that the battery voltage was below the limit I had set in DVCC settings. So I increased the DVCC “Maximum charge voltage” a couple of times and each time the battery voltage increased …

You can now switch off specific alarms in guiv2 on OS v3.55 Device list - inverter - alarm set up

I will be surprised if that works. The high voltage alarms are coming from the battery, not the inverter. I may try disabling the inverter “High DC voltage” alarm. But not within the next several days because it will be cloudy and the battery will not reach full charge. FYI the option is also avail…

[image] davidmnz: FYI the option is also available in GUI V1. Good to know. To be honest i didn’t look. [image] davidmnz: battery high voltage alarms I misunderstood this. Are there cells high at the time of the warnings?

Actually looking at the list of past notifications they all say: Pylontech battery Warning High cell voltage So the alarm is due to high cell voltage according to the battery itself. I have DVCC enabled and a CAN bus connection between Venus OS and the battery. (Strangely all the recent notific…

[image] davidmnz: The cell high voltage warnings are of no value Not entirely true. It is useful for early diagnosis of issues in banks. Particularly if they are repeat cells. From the GX side there isn’t an easy way to stop these. At 57.6 that is 3.6v per cell pretty high i am not surprise…

SOK Battery recommend 57.6 V (3.6 V per cell) for absorption voltage in open loop configuration. Maximum 58.4 V (3.65 V per cell). My understanding of LiFePO4 is that these are widely accepted values. I have set the charge current limit (CCL) to 60 A. I have seen the CCL change to 47.5 A in the bat…

[image] davidmnz: I have never seen the CVL change Yeah. Pylon remains at 53.2v. 3.54v per cell. Some cells may overshoot this voltage which is when the high voltage warning/alarm appears. I have found on older banks they dtart way sooner than that as well. (So get more annoying) Most batter…

Are you feeding back to grid or setting your system to keep batteries charged?

I’m not sure I should follow any recommendations for Pylontech batteries. As I said previously the batteries are actually from SOK Battery. Maybe SOK Battery use the exact same BMS as Pylontech but I don’t know that for sure. I have set the MPPT solar chargers to the values recommended by SOK Batte…

Similar issue. Can’t seem to find a way to turn them off completely or at least temporarily.
