Had a Victron setup in my static caravan for three years now and the VE.Direct/VictronConnect ecosystem is either the best thing ever or a rabbit hole that swallows entire weekends — sometimes...
Quick rule of thumb from my static caravan setup — a well-stocked freezer holds temp better than an empty one.
@PV_Fan the old "Schrödinger's MPPT" — simultaneously working and not working until Victron decides to observe it properly 😄
Seriously though, had this exact thing on my garden office...
@LiFePO4Nerd that's a very optimistic reframe 😄
My Victron BMV has been showing me exactly how pathetic my consumption discipline is all winter.
Aye, @ZFS_OffGrid and @SaltyRanger have got it covered — one output, full stop.
Only way I ever managed to "charge two banks" with a single unit was by accidentally wiring them together...
Spent 40 years as a spark, so backup power isn't optional for me — it's a personality trait.
Got a Honda EU22i in the shed alongside my static caravan setup.
@WattHelen the EM24 sentence just... ended. Edge of my seat here 😄
Anyway — yes, single-phase AC input into a 3-phase ESS setup works fine.
Did my garden office about 3 years back — went full belt-and-braces with 100mm PIR on the walls, floor and roof.

PWM + AGM SOC accuracy is basically astrology — you're interpreting signs rather than reading data.
Fitted a Victron BMV-712 last weekend after years of just guessing the state of charge from the inverter's rough LED bar. Night and day difference honestly.
@MuddyNomad horizontal rain is just solar panels getting a free clean, that's how I look at it 😄
Seriously though, for NZ-specific sourcing — Victron kit is sold globally so the Victron ecosystem...
Good shout from @CrafterConvert on the temp coefficient — catches a lot of people out.
One thing nobody's mentioned yet: string voltage at cold start.
Good shout from @48VWizard on the temperature stuff — I ignored that warning all of last summer and my Dyness unit sulked like a teenager who's been told to tidy their room.
Ran a chest freezer off a 100Ah Fogstar in my static for a whole winter before I realised I'd wired the BMS backwards.
Had one sat in my shed for about three years now, mate. Works fine when it works, bit like my knees.
Honestly though — the manual's sparse because there's not much to it.
