Interesting one this — I had something similar crop up on my static caravan setup last summer but never traced it back to this specifically.
@BurnBen worth asking — what alternator are you running? Older vehicles with a smart/variable voltage alternator can cause real headaches with cheaper B2Bs that don't handle the voltage...
Currently running four 100Ah LiFePO4 cells I got from Fogstar wired up as a 12V bank in my static. Got them balanced and ticking along nicely with a Victron SmartSolar MPPT doing the charging, but...

@CamperJackie snap — had almost exactly the same panic with my static caravan setup when I first got the Multiplus-II talking to VRM!
Quick question for the thread though — does this confusion get...
@Cleggy that's exactly what I'd want to know too! I've got a Quattro on my static caravan paired with a Fogstar Drift lithium bank and I've often wondered what happens when two charge sources...
@SunnyNomad that's the question I keep coming back to actually — because if it's purely emergency backup, a simple trickle charger probably does the job fine at a fraction of the cost.
But where I...
@BoxerAdventure that's actually a really good shout — did you get anywhere with them? Curious whether they have any consolidated docs or just point you back to Victron's website anyway.
I've got a...
Been working on this for months and finally got it dialled in. Built a portable solar box that actually works for weekend trips and garden office top-ups.
The specs:
200W Renogy monocrystalline...
Worth asking the seller if they've got the original documentation and commissioning details — Victron gear is brilliant but you'll want to verify it's been registered properly on their system.

Currently running a Drift 5.12 in my garden office setup paired with a Victron MPPT, and I've got a question that might be relevant for anyone considering multiples like @BayJason and...
Got to push back slightly on the "both" approach — space and budget constraints are real, especially in a static caravan or garden office setup.
What I'm wrestling with is the crossover...
@EdHamilton — couple of things worth considering before you buy:
Winter generation vs. daily load matching — what's your actual winter usage pattern?
Have you lot actually measured your consumption over different seasons though? That's what caught me out with my static caravan setup.
I thought 5kWh per day was reasonable, but soon realised...
Been down this road with my caravan setup. Built a 48V pack from scratch using individual cells and a Batrium BMS — took me the better part of three weekends and I'm reasonably handy.
Been running my setup in a static caravan for three years now. The real game-changer was sizing the battery bank after understanding my actual winter consumption — not summer optimism.
