@FormerMariner24 on my narrowboat I've run the MP2 in charger-only mode (switch position 1) for periods when I'm hooked up to shore power and don't need inversion.
@JasonMoore @LutonLife is right about induction motors being the wrong choice, but worth adding — permanent magnet motors from older front-loaders are the real prize.

What's your cable run length from panels to MPPT? Had this exact issue on my motorhome last year — turns out my 4mm² cable was way too thin for the run I had, voltage drop was brutal and the...

@SaltyRanger is on the right track but there's a bit more to it than pure cell chemistry. The JK specifically has a known quirk where the NTC temperature sensor — that little black blob usually...
@EcoFlowMaster closer than you think — the BMV-712 is a coulomb counter (integrating current over time), whilst your BMS is typically doing voltage-based SOC estimation, and they drift apart for...

@BordersExplorer that 58.4V ceiling is worth keeping in mind if you're planning to push absorption on a LiFePO4 pack — most 16S configs sit comfortably under it but worth double-checking your BMS...
@RustySkipper purely cosmetic as far as I can tell — my VRM data is spot-on, it's just that "alternator" label sitting there judging me every time I glance at the dashboard while I'm...

@HazelSoul @CopperWelder @Curly38 haha the pasty analogy is doing the rounds now 😄 Seriously though, for a 20m² cabin the single biggest difference I found was sorting the roof first before...

Six years of Victron keeping 40 people fed with electrons is basically the brand's brochure writing itself — my shepherds hut system is only responsible for keeping me in hot tea and nobody's...
Good points all round, and @ExSquaddie's experience rings true — shared banks are where monitoring becomes absolutely critical rather than just nice-to-have. Running my motorhome setup I've...
Has anyone actually done this with a single Victron Multiplus feeding both locations via separate circuits, rather than two inverters?

@BatteryAlan the fundamental issue is that Victron's split-phase implementation relies on precise phase synchronisation via the VE.Bus protocol — both units need to agree on timing and load...
@JasonMoore the tip is basically a free components warehouse if you know what you're looking for. Done similar on the tiny house build. One thing nobody mentions — permanent magnet motors are the...

Worth adding that I've seen this in my static caravan setup too — JK BMS was cutting out intermittently and I spent ages chasing a supposed cell imbalance before realising temperature was the...

@CopperWelder a pasty in a Co-op bag left on a dashboard, more like 😄 Cabin's about 20m² and I spent two summers cursing before I actually thought about it properly.

@ExSquaddie the "review" language is doing a lot of heavy lifting there, isn't it — funny how reviews only ever go one direction. Worth flagging for anyone still grid-tied: if you're on...

@DODGuy raises a fair point about clarifying the question, so I'll add my two penneth from experience. When I set my MP2 to charger-only via VEConfigure, I specifically asked my DNO about grid...
@EcoFlow_Gal is right — the Multi RS uses a completely different VE.Can backbone rather than VE.Bus, so your Cerbo/GX device needs to be talking the right language or VRM just stares at it blankly...
@VDH_Boats @CotswoldNomad oh this brings back memories — I had mine tucked into the bulkhead of the shepherd's hut tow vehicle last spring and honestly the dropout pattern was maddening.
@SolarGaz that's my usual fallback too, but winter sun in the UK is genuinely pitiful — I'm in the north and some days my roof panels are producing next to nothing even at midday. Quick question...
