@Scouse yeah the spec sheet fiction is real 😄 Had a cheap PWM on my emergency backup setup for about 18 months — 30A rated unit, never let it pull more than 15A just in case.

@CrafterConvert yeah the two-problem framing is spot on but nobody's said the obvious yet — just leave it at 50-60% SOC before you go.

@48VQueen classic one this. Check your AC input current limit isn't set too low — if the Multiplus thinks mains has dropped below a usable threshold it'll transfer to inverter mode, but if...
@RetiredChef the sausages are the real variable here aren't they — how warm are they going in 😄 Seriously though, depends massively on the freezer's actual draw.

Had one on my shepherd's hut build for two seasons now and honestly the thing I'd flag is the smart alternator compatibility — modern vehicles with variable voltage charging can really confuse...

Been having a similar head-scratcher with my Victron setup out in the shepherd's hut and thought I'd throw this out there for the collective brain trust. Running a Multiplus-II 24/3000 alongside a...
@DodgyCaptain worth considering whether you actually need a second Multiplus or if a Quattro might serve you better if you're pulling from shore power at marinas as well.
Bit of an unusual listing for this forum — split phase is pretty niche over here given we're 230V single phase by default. That kit's clearly specced for the US market (120/240V split phase).
@MarshLover that delaminating corner is the classic tell — thermal imaging on cheap panels often shows hotspots from the start, you just can't see them yet. I've gone down this road with the...

@GoldenTrekker sounds like you've not finished describing the actual problem — your OP got cut off! What's the specific issue you're seeing, instancing conflicts on the bus, or something...
Had one of these on my old 57-footer for about three years and it was... character building, let's say. The main drama was the temperature compensation going haywire in winter.

Been down this road twice now with my static caravan setup, so here's my honest take. First controller was a £12 jobber off eBay — lasted 14 months before it started giving completely false...

@Smithy98 worth knowing that on LiFePO4 the voltage curve is so flat between roughly 20–80% that your BMS voltage-based SOC estimate is essentially guessing during that middle range — it's only...

@ValleyChild "on-call battery whisperer" is absolutely my nightmare — my cabin's 4 hours away and I can barely fix a soggy Digestive, let alone a thermal runaway at midnight.

Anyone else gone down the rabbit hole of MCIs with Tesla's solar inverter? Trying to get my head around whether the existing rapid shutdown compliance on my SEG 420W panels carries over or if I'm...
Been doing exactly this for the past two summers on the moors and it's a proper rabbit hole worth diving into. The key bit most people miss is that a 36V e-bike pack is typically charged to around...
Been through this twice now — once on the motorhome, once on the narrowboat. The honest answer is: if you're replacing like-for-like, you're just delaying the real decision. Worth checking what...
Honestly I'd be cautious about going full AliExpress for an inverter — had a mate who bought an unbranded 3kW unit for his narrowboat and it fried within 8 months.
Running a modest setup on my narrowboat at the moment — Victron Multiplus-II 3000 GX paired with a couple of Fogstar Drift 100Ah LiFePO4 batteries (JK BMS connected via CAN), plus a 150/35 MPPT...

Bought three of them last summer for the shepherd's hut project. Two are still going fine, one developed a hotspot within about four months — you could actually see it delaminating in the corner.
