@WayneJames keen to see the wiring diagrams when you get there. The 2170 cells in those packs are seriously good chemistry — should hold up well for static use. One thing worth looking into early:...

Not directly relevant to my setup (single-phase motorhome install with a Victron MultiPlus-II), but I've seen similar phase-calculation oddities mentioned in the Victron community forums. Worth...

Has anyone actually compared the efficiency losses between a cheap PWM and something like a Victron BlueSolar MPPT on a small system?

So the bit nobody's mentioned yet — what actually prioritises between solar and grid on AC-out-1 in that scenario? From my static caravan setup running a similar config: when solar (via MPPT) is...
@PennineCamper had exact same issue with my static van last winter — 200W just doesn't cut it when you're getting 3-4 hours of proper sun on a good day. Ended up adding a portable 100W panel I can...
@AnneWatson's point about BMS disconnection is worth pursuing — is your MultiPlus set to ESS or standalone inverter mode?
Done this on my narrowboat for the past two winters so can offer some real-world numbers. A decent small chest freezer (I run a Sealey 35L) averages around 25-40W depending on ambient temp.

@Tel1968 worth checking your AC Input Current Limit in VE.Config as well — if that's set too conservatively it'll clip before PowerAssist even gets a chance to compensate properly. Also, what's...
Depends massively on what you're calling "basic" tbh. I've got a garden office running off a 200Ah and it's honestly not overkill at all once you factor in monitors, a small heater,...

@Midge52 I know exactly what you mean. Did my narrowboat conversion three summers ago and every time someone on the marina shows me their electricity bill I feel this smug little glow inside —...

@JackeryGuy the EV charging angle is what interests me most here. If you're running something like an EVSE off this setup, the voltage stability from the battery source probably helps the micro...
@RetiredEngineer harsh but honestly fair — I've got 400W on my shepherd's hut roof and still watched my Victron BMV-712 weep quietly through November like it owed me money. The real fix that saved...
@LisaStewart71 is right to flag the BMS — that's where most of these builds go sideways tbh. One thing I'd add though: have you thought about whether Victron kit will actually talk to whatever BMS...

Right so this is basically my origin story too — sitting in my static caravan one evening watching the electric meter spin like a fruit machine and thinking something has to change. Took me about...

@48VWizard this is a classic frequency-shift rejection loop and I've tumbled down exactly this rabbit hole myself.
@LutonCamper has covered the watt-hour maths reasonably well, but there's a critical nuance being glossed over here. The Fogstar Drift 200Ah is a 12V unit, giving you ~2400Wh nominal — but Fogstar...

@PanelEwan @Spider — worth checking the LPG regulator itself under load. A lot of budget regulators will show fine at idle but effectively starve the carb once you put any real demand on it.
Hey @Nessa68! Really depends what you're running in the shed to be honest. For basic lighting and maybe charging tools, a 100Ah lithium is usually more than enough - you'd only be using a fraction...

Both posts got cut off mid-sentence, which is deeply unhelpful for anyone searching this thread later. That said, I'll throw in what I know from my own van setup.
@QJ_Builds has the passthrough side covered, so I'll add the nuance that matters practically: With grid on AC-in and solar coming via MPPT, the GX will prioritise solar to cover AC-out-1 loads...
