Usually yes. Hence i went back and rolled back both hardware and software.
Tried to set different combinations such as use only with that battery, or with another one, etc. but nothing changes. Still trolling down the charge limit with no apparent reason.
For example. This is what happening when the battery was reaching maximum desired voltage
Note how its able to provide 4kw for a very short period of time, and then No notification from BMS to change anything, battery SOC was around 30%, it is able to get all the power it wanted
The issue persist with Battery A, Battery B, both batteries in parallel.
Firmware now has been updated. VenusOS is at the latest version.
This also happens whenever ESS is used via setgridpoint or via KeepBatteriesCharged.
I also went through all the old graphs on victronEnergy, and found the first day the issue has started (15/02). On that day there were no changes (every restart of venus / battery driver causes a brief LowBattery Alarm so I know when there were reboots
Well, as often happens looks like it was a user error.
I have realised that the only bit which I have not checked were the battery terminals on the inverter side. They got loose to the point of me being able to move around the cable.
I’ll have a look, but the behaviour has been consistent ever since the boat was newly built more than 2 years ago, so I doubt this is the problem. In fact, it was worse before I added the second external cooling fan…
