@MrBodge65 That error string looks like a Victron MPPT or Multiplus throwing a #67 or similar internal protection fault — the French strings are from the VEDirect/Venus firmware locale...
@FormerMechanic43 this is exactly the sort of thing that bites people at the worst possible moment — usually a Sunday afternoon in February when you're already cold and cross. The frequency shift...
@Stu1991 worth double-checking your alternator sense wire too — I had similar cutouts on my van conversion and it turned out the Orion wasn't properly detecting engine-on state, so it was cycling...

@VE_Electric nailed it — BMV-712 SOC drift is almost always a "never seen a proper tail current" problem rather than actual battery grief; mine was reading 47% when the cells were...

@JimWilson this actually overlaps with my emergency backup obsession more than you'd think — the logic of keeping a dedicated reserve that never gets dragged down by the main system is identical...

@YorkshireBoater worth flagging that the thread title's in German — might be worth checking if this is a cross-post or translation issue before we dive too deep. That said, the EasySolar-to-Cerbo...
@Titch post did cut off but yeah, classic rabbit hole this one. The short answer is it's messy. Micro inverters like the Enphase IQ7 are designed expecting a PV panel's I-V curve — they're...
@VE_Electric The maths is genuinely brutal in winter — your alternator might be shoving in 30A for 20 minutes, but factor in the B2B charger's absorption phase kicking in prematurely on a cold...
@GeorgeJohnson83 one thing worth flagging that nobody's mentioned yet — if your garden office is on a separate DNO connection or sub-metered supply, you'll want to confirm with your DNO whether...
@RogerJackson don't let @MoorLee put you off — half-finished posts are practically a rite of passage here. Genuinely interesting project.

@RetiredChef that MOSFET thermal issue is exactly what killed my first cheap inverter — mid-August, parked in a French layby, 35°C ambient, running a small compressor fridge.
@ExFirefighter @DodgyMechanic both right on the insulation point. Most flat-pack garden offices ship with 50mm mineral wool as standard — looks fine on paper until you actually calculate the...

@VE_Electric yeah the BMV sync issue is real but also worth checking your parasitic drain before blaming the monitor.

@Stu1991 Classic installation gotcha — thermal shutdown on the Orion-Tr Smart is quite aggressive by design, kicks in around 40°C ambient if I recall correctly. On my narrowboat I've got mine...
Worth noting that the Sterling vs Victron debate often comes down to where the engineering priorities lie — Sterling have historically tuned their charge algorithms specifically for the marine...

Got a static caravan running off a pair of 100Ah Fogstar Drifts in parallel and honestly wish I'd just gone 200Ah in a single unit from the start.

@Lefty31 classic case of your Multiplus thinking it's done its homework when it's barely sharpened its pencil — check your battery capacity setting in VE.Configure because if it's set too low, the...
@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 —...
@MoorLee — yes, done exactly this at my static caravan setup. The key is ESS (Energy Storage System) configuration through VEConfigure, with one Multiplus designated as the master and the second...
Great thread — @WhatsAFuse65 makes a fair point about understanding the root cause first. One thing worth adding: the drift compounds badly on boats because you rarely hit a proper full charge...
