I made screenshots (using remote control) of the high and low cells in Victron Color Control GX when I had the alarms today. The 0101 was high a couple of times and then the 0103 was high.
I lowered the charge voltage to 51V right now and I’ll observe behaviour change tomorrow.
The idea with wine on a Linux system to run the BatteryView on Windows made my day 
(I do NOT like to have Windows on my computers).
2 days later since I lowered the charge voltage to 51V and:
51V is too low to charge them properly
I know, but I believe it is NOT hurting the batteries, but rather keeping them safe. Correct me if I’m wrong.
I’m planning on keeping it 51V till I get the problem fixed:
All you need to do is keep the highest cell just below a threshold. All that needs is 100-150mV, so you can keep raising the CVL until you get to a happy point.
You can both have a (near) full battery and happy cells.
Take the normal CVL and drop 1V off it. If that has a good result, add 0.2V increments until you get to a suitable spot or the problem resolves.
Starting too low is throwing away capacity unnecessarily.
Looking into it, the Charge Voltage of my US3000C battery modules is: 52.5V ~ 53.5V (though I’ve read that recommended max is 53.2V)
How do I get the CVL (Charge Voltage Limit) from it?
I’ve already tried 52V and 51.7V. Both of them did NOT help, I was still getting the high Voltage alarm.
I might try to go slowly up from the 51V and observe how it goes.
Good morning,
Very good, now as above said, these battery modules are 15 pieces, so, per 0.01V per cell increase 0.15V overall and check that during charging to “full” that cell stays under 3.60V.
Normally we set it to 3.57V, so, try 51.15-51.30-etc, till no alarms and a higher charged percentage, and don’t be afraid the BMS equalizes the cells already just above 50.40V when charging, that will start normally a little higher in practice (temperature of the cells) at about 50.47V.
Also, you will notice that this 51.00V at the moment will be around 51.07V, and also due to the lower voltage you see at around 87-90% charge a flat for some 5-20 minutes, that’s the point the BMS is equalizing the cells, after it rises higher again.
See, one install with almost exactly the same issue here, a bit less as yours.
Here you see that cell go up to 3.57V, and the graph above this one, the voltage is kept flat, to give that cell the time to lower.
Another thing, place the “problem” unit in the middle of your stack, as there it receives then just so slightly less voltage and so the other units get charged a bit higher, worth trying.
