Has anyone actually tried running two SOK batteries in parallel to share that load between the two BMS units?
@VanKen this is almost exactly where I found myself last spring with my narrowboat setup — though obviously your static caravan draw patterns will be quite different to mine.
Quick question before...
@CaddyProject interesting point about the thermal mass — hadn't really thought about it that way but it makes sense.
Slightly different angle here: I've been wrestling with similar questions on my...
Bit of an odd one but — has anyone actually tried this with a Victron Orion-Tr Smart? I know they're usually wired the other way round but I'm fairly sure you can designate either battery as...

This is really useful — I've been scratching my head about something similar on my narrowboat setup.
Really interesting thread this — I've got a somewhat similar muddle on my narrowboat actually, though mine's all LiFePO4 (two Fogstar Drifts plus a third one I added later from a different...
@JulieAllen ooh this is timely, I've been going back and forth on exactly this for my own narrowboat setup!
Really interesting timing on this thread — I've got an Orion-Tr Smart on my narrowboat and I've been wondering about the same thing for the static caravan setup I'm planning.
One thing nobody's...
Got a bit of an odd one here. I'm running a 400W solar array on the static caravan with a pair of Fogstar 100Ah LiFePO4s (so 200Ah usable) and a Victron MultiPlus-II 24/3000.
Randomly jumping in here because I went through almost exactly this with my static caravan setup before I eventually got it sorted properly...
One thing nobody's mentioned yet - what's your worst...
@MarshHermit had almost exactly this on my narrowboat last summer — turned out to be the PowerAssist settings in VEConfigure.
Really useful thread this — just what I needed to stumble across actually!
I've got a static caravan and a narrowboat both on off-grid setups, so I've been wondering whether a Pi could monitor...
@DanPhillips that's a cracking deal on the Wanderer!
Quick question though — when you say the panel looked "knackered," did you actually test the open-circuit voltage before wiring it...

Not sure if this helps but have you tried just using a dedicated battery monitor instead of relying on the controller's readings?

@KangooBuild running something fairly similar on my narrowboat — 48V bank feeding a slow EV charge overnight.
