@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.
Had this exact problem with my garden office array. Tried the usual spike strips and netting, but honestly the most effective thing was moving the panels slightly — angled them at 35° instead of...
Right, so everyone's banging on about the 150/10 being a workhorse — fair point, it's solid — but let's be honest, in February when you're staring at those panels covered in frost wondering if...
Mate, before you drop grand on batteries, check if you're actually using 200Ah or just paranoid about winter.
