Took the motorhome out to the Cairngorms last weekend. Forecast said -3°C overnight, so I ran the Webasto AT2000 pretty much continuously from about 10pm to 7am.

SamKing | 203 posts One thing nobody's mentioned yet — make sure you've got both units configured as "engine running only" mode in VictronConnect if you're bothered about draining your...

Had this in my shepherd's hut last winter with a similar sized inverter. The thing that finally cracked it for me was checking the transfer switch settings in VEConfigure — specifically the AC...

@VanAmy I'm in a similar situation on my static caravan — ended up wiring a 175W and a 100W together into a Victron SmartSolar 75/15.

Reply by Tom1997: @Kingy74 Worth checking your AC output frequency settings in VictronConnect — I had similar grief and it turned out my MultiPlus was hunting slightly on frequency under heavy...

@CallumHamilton83 not imagining it at all — the difference is very real. I made the same swap on my static caravan setup a couple of years back.

Been running the Renogy 40A on my shed setup for two seasons now — 3x200W into a 24V Fogstar bank — and honestly the most exciting thing that's happened is a firmware update I did voluntarily out...

Been in almost exactly this spot myself — same MultiPlus model, similar battery capacity. What tipped things for me was tracking actual peak draw versus the inverter's rated output.

Hey @Mark1978, sounds frustrating but pretty normal behaviour with new prismatic cells to be honest.

Been sitting at a French aire for the past three weeks running the motorhome entirely off a 600W roof array and a pair of Fogstar Drift 100Ah lithiums, which has been brilliant.

TimHarris | Posts: 293 | Location: Shropshire @Trevor1975 I had something similar on my Pixel 7 after the Android 14 update.

WendyFisher61 | 312 posts Had the exact same question when I set up my narrowboat last spring. The Cerbo does a reasonable job piecing things together, but without a shunt it's essentially...

AshSeeker | 31 posts @EdHamilton Really interesting question — I'm in a similar position, having spent time optimising solar on a narrowboat before thinking about mobile setups. One thing I'd flag...

@CamperAndrea — pull the split-charge relay out and don't look back. Ran exactly this combo on my old Ducato for about six months, thinking the relay gave me a useful "backup path." All...

@Brummie86 had something similar with my garden office build. Cell 3 going high at top of charge is usually the one that's slightly higher capacity rather than the weak link — it charges faster so...

EdStewart | 562 posts | ⚡ Off-Grid Tinkerer One thing worth flagging that I haven't seen mentioned yet — the vibration tolerance of your BMS is worth checking if you're genuinely sharing hardware...

@RogerKnight is right that the why matters here. The B2B charger handles voltage conversion and current limiting itself — it's designed to protect your alternator regardless of battery chemistry.

@RM_Marine worth checking the voltage at the input terminals of the DCC50S itself rather than just at the battery.

Jonno71 | Posts: 847 @DerekDixon Go lithium from the off if your budget stretches to it, honestly. I made the mistake of starting with AGM on my cabin build thinking I'd "upgrade later"...
