Been scratching my head over something similar with my Vivaro-based build, so thought I'd throw this open for discussion. My setup runs a Multiplus-II as the main inverter/charger, with DC input...
@KellyRobinson "tucked behind a bulkhead" is basically Victron's way of saying "please throttle me gently into oblivion" 😄 Mine's in a garden office setup and I made the rookie...
Bit of a work-in-progress post this one, so bear with me. Been slowly pulling together an all-Victron setup on my static — Multiplus-II, Cerbo GX, SmartSolar MPPTs, the lot.
Had exactly this with my 100/30 last summer. Turned out the absorption time was set too short in VictronConnect — it defaults to a fixed 2 hours but if your battery isn't fully charged by then...
@Nessa depends entirely on the freezer's actual draw. Chest freezers are cyclic — mine pulls ~2.5A when compressor's running but sits idle maybe 60-70% of the time in cool ambient.

@BaySoul one thing I'd add that nobody's mentioned yet — check whether it actually ships with a proper BMS that handles low-temperature cutoff.
@OddJobBob that rabbit hole is very real. I spent three evenings aboard my narrowboat squinting at cell markings with a head torch trying to work out whether what I'd bought from a suspiciously...
Narrowboat life sorted this one out for me sharpish — 100Ah is basically just about adequate if your fridge is halfway decent and you're not in the Arctic. Few things that made the difference on...
@MuddySkipper that's exactly what I'm trying to figure out for my shepherd's hut build. The hut came with a fairly basic inverter/charger combo and I'm looking at a Victron MultiPlus as a...
Really interesting thread — @AnneWatson's low-temp point is spot on and worth adding to. One thing nobody's mentioned yet: even if the ambient temperature reads fine, the cell temperature sensor...
Running my narrowboat through another blistering British summer (both days of it), so this feels like a timely question for me too! I've got a Fogstar Drift 200Ah sitting under my galley bench and...

Been thinking about this one for my cabin setup and figured it'd be worth getting some other opinions in here. Running a SmartSolar 250/100 Tr myself, with a max PV string voltage of around 148v...
@PartnerAdventure really curious about your dual-use setup there — van and home backup is exactly the kind of thing I've been pondering for my own conversion. Quick question though: when you say...
Good points from @BoatJason and @BoatPaddy already. One thing I'd add — check your battery voltage sense setup.

Seen a few of these pop up on eBay and Amazon lately. The price point is tempting, no question — but I'd want to know a lot more before putting one anywhere near my setup. A few things I'd be...
@ExBrickie31 raises a good point about hardwired outputs — worth adding that if you're going down that route, you'll want to check whether the inverter's output terminals are rated for the cable...
@PennineSolar worth checking whether the alert is tied to the Multiplus-II internal temp sensor or your battery BMS.

Been lurking here for a while and finally have a question I can't find a clear answer to anywhere. I'm planning a fairly ambitious setup for my tiny house build — it's going to be grid-tied but...

@BoatPaddy's "decorative ornament" is doing real work on my conscience because I've lived that exact scenario — shepherd's hut, December, south-facing 200W panel, and my Victron BMV...

Ran this exact setup in my cabin last summer — Victron MultiPlus handling the overnight storage side whilst a cheap Enphase microinverter on the south-facing panels feeds straight into the AC...
