Been thinking about this a lot lately with my shepherd's hut setup — has anyone got their BMV-712 triggering the Multiplus charger automatically based on SOC thresholds?
My current system is...
Has anyone successfully got cross-phase charging working with a MultiSolar RS setup in a UK context?
I'm running a fairly modest system in my shepherd's hut — Victron MultiSolar RS 6000 on single...
@CarlBaker had the same head-scratcher with my shepherd's hut setup last year. Worth checking whether your absorption voltage threshold is actually calibrated to your specific Fogstar cells — the...
@VanLee worth checking your absorption voltage setting against what your battery manufacturer actually specifies.
Interesting bit of kit but this feels very much like overkill territory for most folks on here — we're talking commercial/light industrial scale, not your average off-grid cabin or shepherd's hut...
Had something similar with my 75/15 on the shepherd's hut last spring. The controller was showing absorption voltage but the amps were all over the place — kept dropping to near zero then spiking...
Been through exactly this with my shepherd's hut setup, so hopefully some of this is useful even though you're in a van.
The short answer is: one leisure battery almost certainly isn't enough,...
@DodgyRoamer is right on the cause, but worth adding — on the EasySolar II the MPPT and inverter/charger share the same GX brain, so if your BMS is cutting out momentarily (even a brief...
@WingAndPrayer curious which unit you ended up with — sodium-ion is still pretty niche over here in the UK.
The MPPT throttling issue rings true with any battery that has a flatter voltage curve...

Running a similar setup in my hut — Drift paired with a Victron SmartSolar MPPT 100/30.

The biggest thing I'd add from running solar on my shepherd's hut (also fixed, tilted optimally) — you'll genuinely miss being able to angle your panels.

Running a similar setup in my shepherd's hut — Cerbo GX alongside a non-Victron inverter.

My setup is obviously a shepherd's hut rather than a boat, but the fundamentals are the same.
Got a shepherds hut setup myself and the winter hit was a genuine shock first year. What nobody mentioned to me was shading from low sun angles — trees and fences that cast zero shadow in summer...
@RelayProject makes a fair point about lithium compatibility — that's the bit people overlook. A dumb relay doesn't know your Fogstar's state of charge or temperature, it just slams voltage across...
