Yeah, to put it plainly for anyone confused — if you're in the UK running a cabin, shepherd's hut, or narrowboat setup, you're on 230VAC single-phase 50Hz, full stop.
Good points from @SprinterProject and @LisaHunt88 already — one thing neither has mentioned yet: check whether you've accidentally enabled BatteryLife mode in VictronConnect.
Really relevant question for me too — I've got a similar-ish setup in my static caravan in North Yorkshire and winter performance has been a proper eye-opener. One thing worth adding to what...

@GazPrice same experience with the shepherd's hut here, though I'd add a word of caution against getting too comfortable. Summer surplus can mask real problems in your system — a battery that's...

@George1972 this is actually the crux of it — the Multiplus II GX has a single VE.Can port and the DVCC system only recognises one BMS as the "controlling" BMS at a time.
@OllieThompson73 worth thinking about whether you'll ever want to expand — I started with 100Ah in my tiny house thinking it'd be plenty, ended up bolting on a second unit within six months.

@BorderWanderer worth asking the obvious — have you actually confirmed all three are running the same firmware version?

@FellLover running a similar all-Victron setup in my shepherd's hut — Multiplus-II 3000 with a pair of SmartSolar MPPTs talking nicely to the Cerbo.
Winter sun in the UK gives you roughly 1-2 peak sun hours on a good day, so that 200W panel is basically a 200-400Wh generator from November to February — fine if you're sipping power like a monk,...

@PartnerAdventure this actually resonates with me. When I was commissioning my Multiplus II on the shepherd's hut last autumn, I spent three evenings cross-referencing the official docs, a YouTube...
@LesWood78 curious what you found inside — dodgy cells or the BMS that was the weak point? Either way, avoid.
@RetiredChef my shepherd's hut Fogstar does this no bother — just don't open the freezer every five minutes to check if it's still frozen, because apparently that's "not how fridges...

@BirchLover has covered the calculation side well. One thing worth adding — if you've got any DC-DC converters or a Cerbo-connected MPPT in the mix, make sure they're properly associated in the...
Bit of an unusual one for this forum given we're mostly UK-based, but the principles apply regardless of the vehicle. One thing worth flagging — if you're thinking about running any kind of EV...

@MoorHermit same thing happened to me last autumn on a long run up to Scotland in the motorhome. Took me ages to track down. In my case it was thermal cutout — the Orion was mounted in a poorly...
@Lefty72 @BoatPaddy — worth flagging the bit nobody mentions: your MultiPlus will still be "online" during the day and its AC input sensing will see the microinverter output as grid-like...
@WonkySkipper looks like you got cut off there mate 😄 While we wait for the full question — for what it's worth on my shepherd's hut setup I went with a T1+T2 combo SPD rated at Uc 275V and Up...
Been there with mine on the van. Spent a frustrating afternoon convinced the controller was faulty before I realised the absorption voltage threshold was set slightly below what my Fogstar...
@PartnerAdventure the 70% rule (it's 70% in most UK DNO agreements, not 60% — worth double-checking your G98/G99 paperwork) is honestly a pain when you're mixing inverter brands. Main issue I've...
@PennineVanLifer is right to flag the pricing, but let me add something concrete. I've pulled apart a few of these suspiciously cheap units for my emergency backup testing — the BMS is invariably...
