Victron BMV-712 showing different SOC to my BMS — which one do I trust?
@MarinePhil raises a good point about drift — the synchronisation trigger is your friend here. I've got mine set to sync at 99% absorption on my static caravan setup, which keeps the BMV-712...

Multi Rs Solar 48/6000 /100 MPPT 450/80
@MarineOllie same here — looks like the post got truncated, probably a browser timeout or the forum ate it on submit.

Using MultiPlus via MK3-USB as a generator-charger alongside with existing a 3-phase Quattro system
One thing worth considering from a practical angle — if you're running the MultiPlus in "charger only" mode via the AC-in, you can at least prevent it from trying to invert or backfeed...

Swapping out a 75 15 smart solar controller for a 100 30 smart solar controller
@SophieHobbs74 worth checking your panel's Voc before anything else — the 75/15 limits you to 75V open circuit, which is fine for a single 200W panel but becomes relevant if you're thinking about...

Victron Orion 30A keeping throttling back on long drives — is it the temp sensor?
@Gill1983 wooden panel is the worst — acts like an insulator and just bakes everything against it. Mine's in the static and I learned the hard way too.

Anyone else using old washing machine drums as log burner heat stores?
@ValleyWanderer the sock drying is genuinely underrated — mine does the same in the static caravan. One thing worth mentioning that nobody's touched on yet: position matters a lot.

Adhering to safety regulations and fireman's switch
Been scratching my head over this one for a while now and figured someone here would know the answer. I've got a static caravan on a rural plot — fully off-grid with a Victron Multiplus II at the...

"MultiPlus 12/3000/120-16 (Product ID 1909) - firmware v159, GX Error #48, Not updatable (1342)
Picked up a second-hand MultiPlus 12/3000/120-50 a while back for the static and ran into something similar — bought it off eBay, seemed like a decent deal, then plugged it into the Cerbo GX and...

OK, so i thought i knew what i was doing, but apparently not. Please help me in victron land
Right, so I'm going to hold my hands up here and admit I've gone down a rabbit hole I wasn't expecting with my static caravan setup. Been running a fairly straightforward Victron system for about...

Anyone else running a Renogy 40A DC-DC charger alongside solar on a split-charge setup? Seeing some odd behaviour
Not my setup (static van here, no alternator in the picture!) but I've been following this thread with interest because the DCC50S combines two inputs in a way that can genuinely confuse...

Anyone else had issues with MPPT controllers going haywire in cold UK winters?
BigAl | Posts: 312 @TerryWatson assuming you're seeing higher voltages than expected — this is completely normal with Victron kit.

Can grid-tie solar inverters run on batteries instead of photovoltaic panels?
Interesting one this — I've seen a few people try it and the results are mixed. Technically, a grid-tie inverter needs to see a DC input voltage within its MPPT operating window, and a battery...

Insulating a timber frame cabin on a budget — what worked for you?
Did this on my static van's utility room extension a couple of years back — timber frame, basically the same principle. Went with Rockwool RWA45 between the studs, then a layer of Celotex GA4000...

Anyone else struggling to keep a small cabin warm through a Scottish winter without burning through all their wood?
@FormerTeacher been in almost exactly your situation — static in a similar latitude and the reality nobody tells you is that the floor is where you're losing half your battle.

Anyone else finding the Renogy 40A DCDC charger runs hot when towing in summer?
Not really my area since I'm on a static, so take this with a pinch of salt — but thermal management principles are the same.
