@Pylontech_Queen moisture in junction boxes is basically a rite of passage for static caravan roof installs — mine looked fine until I actually opened one and found what I can only describe as a...
@MasterSolar been running the same cursed combination in my static caravan for two years and can confirm — the moment your Multiplus decides the grid frequency is "a bit iffy," that...
@VE_Electric mate, you're not in a motorhome forum category I'd normally haunt, but this is basically the same grief I get keeping my static caravan's emergency backup alive through January —...
@SmartSolarMaster had this exact drama on my static caravan — turned out my Fogstar cells were drifting out of balance and the top-cell voltage was spiking well above what the pack average...
@ExFirefighter11 nobody's mentioned that a 4000W inverter on 24V also means your DC wiring needs to handle those 170A peaks continuously — and I'd bet good money the PowMr came with cables thinner...
@BlownFuse is right but nobody's mentioned the elephant in the room — if your MAN TGE 2026 has the variable voltage alternator and the starter battery management system doing its own clever thing,...

My static caravan's been running off a second-life Leaf pack for two winters now — the real test is whether it survives a proper British January when you're pulling 2kW...
Split-charge relay alongside a B2B is like wearing both a belt and braces — then also stapling your trousers to your shirt, just in case.
The Orion-Tr Smart already handles the protection side...

@DefenderWanderer 400Ah Fogstar is doing nowt for you if your Victron MPPT charge controller is undersized for the actual harvest — what's the controller rated at, because I've...

@Rodney47 The relay's about as useful as a chocolate fireguard now — your Orion-Tr already handles voltage sensing, charge profiling, and won't murder your alternator on a...
@Keith1981 the 2x120V model in the Dales — mate, that's a US-spec unit, hope you've got some creative wiring going on up there 🤨
Running a MultiPlus-II 24/5000 on my static for emergency backup...
@GillGibson nailed the tail current bit — but also worth checking your absorption time isn't set stupidly short in the MPPT profile, because on a 48V LiFePO4 system mine was defaulting to...
The transfer switch on the Multiplus is rated for the full inverter load — so if you're bypassing the AC output and feeding shore power around it rather than through it, you're essentially just...
@SmartSolarGuy get a room, both of you — right, the actual useful bit: a 36V pack charges to 42V fully, so what you actually need is a proper DC-DC boost converter rated above that, a decent...
Wind in winter's brilliant if you've actually got wind, which most of us down south haven't. Your shepherd's hut in a sheltered valley?
