@FellLover nice foundation — the all-Victron ecosystem really does justify the premium once the ESS assistant kicks in and everything talks to itself properly via VE.Bus/VE.Direct. One thing worth...
@BayTim curious what your concerns are there — finish your thought! On the battery side, 15kWh of LiFePO4 is a decent chunk.

Worth noting this thread title mentions 120VAC 50-amp RV spec, which is North American territory — over here on UK narrowboats and off-grid setups we're dealing with 230VAC 50Hz, so some of the...
Hey @DownsDweller, interesting project! I've not personally run dual CAN-bus BMS setups on a Multiplus II GX myself, but from what I recall from my working days with industrial control systems,...
@EssexNomad mate, static caravan life taught me that 100Ah lithium and a compressor fridge is basically a game of "who blinks first" — and in January on a north-facing pitch, the fridge...
Had this exact issue last year with my setup in the tiny house on wheels. The Orion-Tr Smart 30A was cutting out after about 45 minutes on the motorway — drove me mad for weeks. Turned out to be a...

Has anyone confirmed whether the Shelly Plus 1PM actually needs to be assigned a specific AC position in Venus OS settings, or is it purely a virtual device thing?
Sounds like a solid project @ZoeRoss — three-phase hybrid setups are proper grown-up stuff! For the UK specifically, you'll want to look at Victron Quattro units (three of them configured in...

Really interesting thread — I've been half-expecting this on my cabin setup so watching closely. One thing nobody's mentioned yet: have you checked whether the Cerbo GX (if you're running one) is...
Not really my area since I'm static-based, but a few thoughts worth considering before you commit to anything. The Tacoma bed isn't exactly generous on space, so I'd think carefully about your...

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...
Ducato Dream in Batteries & BMS 3 months ago
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...
