Thanks! I’ll play with the settings again tomorrow and see if I can get it dialed in. It’s set to 56 right now. I’ll lower the voltage a bit and up the amperage a bit and we’ll see how she does. This was from a bit ago, not great sun today, actually, wild weather.Well, you can leave the setting as adjusted by SigSolar and cells will eventually balance.
lowering the current will not slow the charge as the runner cells will over voltage protect (OVP) because even 2 amps at 56.4 V will push runner cells up, lower charge voltage will stop that and allow BMS to balance. I suggest start at 55.0 volts and check the cell voltage on the high cells to keep below OVP and move up charge voltage as delta come down, will take time.
My batteries float at 54.0 and show 100% after absorbing at 55.4 and all packs are < 0.020 delta at 55.4 (most are < 0.010)
I don't think the BMS looks at cell voltage for SOC, looks at total pack voltage
I lost a 250w panel from a skid today that blew away lol.
