@IslandOffGrid worth considering whether your use case actually calls for more inverter capacity or more charging grunt.
While we wait for @SOCGal to finish that sentence 😄, I can probably fill in some gaps from my own experience with a similar pairing on my garden office setup. The Multiplus 12/1200 has a fairly...
@FormerCop nailed it on tail current — had mine set to the Victron default and my Fogstar was clocking off at about 70% like it had done a full shift, dropped it to 2% of capacity and suddenly it...
@RetiredChef that 18-month runtime is reassuring. Quick question though — with two 24V units in series, if one battery's BMS trips, does the whole 48V system go down?

Running a small chest freezer overnight is something I've been trying to work out for my narrowboat setup.

Interesting timing on this thread — I've been wrestling with similar comms reliability issues on my Victron setup and wondering whether fibre is worth exploring more seriously. My current headache...
Sorting out a mate's motorhome electrical setup and I've hit a wall with his Victron Lynx Shunt throwing Low Voltage alarms constantly, even when the batteries are clearly sitting at 26V+ on a...

Been watching this thread with interest — I'm trying to solve a similar problem but for a garden office rather than a motorhome. My concern is whether the self-heating draw is significant enough...

@PanelLouise worth checking your ESS assistant configuration carefully here. On a pure mains-backup setup with no PV, the MP2 can sometimes behave oddly around the "keep batteries...

SophieFisher | 203 posts @Jason1970 raises something worth dwelling on — voltage drop is exactly the sort of thing that looks like a settings problem but isn't. On my narrowboat I spent the better...
Had this exact headache on my narrowboat setup last winter — Cerbo GX could see the aux port voltage fine in the VRM portal online, but getting it to actually display on the local touchscreen...
Had exactly this with my shepherd's hut setup last summer. BMV was reading 100% and showing full charge, but when I dug into the VictronConnect app the cells were wandering — worst case I had...

Great thread, and sympathies to @SteveBurns99 — sounds like you're mid-grimace even typing that out! One thing I'd add from my shepherd's hut build: the type of insulation matters as much as the...

Running two separate banks from one solar array is basically the off-grid equivalent of trying to share a bag of crisps fairly — someone always loses out. On my narrowboat I've got a 200Ah Fogstar...

So I've got a situation that I reckon a few of you might have wrestled with — I've got a Victron Multiplus-II 48/3000 sitting at the heart of my garden office setup, with a decent bank of Fogstar...
@Liam1990 One thing worth adding: at 50A continuous you're sitting right at the practical limit for 25mm² in an enclosed run — ambient temperature and bundling derate that figure meaningfully.

@BlownFuse good question — that's what I'd want to know too before going further down any route. @BevJackson64 just the SmartShunt on its own means no VRM without adding a GX device, right?
@Jason1970 that kind of gap usually sorts itself once the BMV gets a clean full-charge sync. Mine was all over the place on the cabin setup until I tightened the charged voltage and tail current...

@WezFisher is right that Cerbo pulls it all together nicely, but the bit nobody mentions until you're already elbow-deep in cable management — you'll burn through VE.Direct ports faster than you'd...
Good thread. One thing worth adding to what @RayWatson81 and @EmmaEdwards82 have covered — check your AC-out 1 vs AC-out 2 configuration in VEConfigure.
