advice on alternative inverter CNSWIPOWER 1500 W 48v and CNSWIPOWER 1500W 48v
Right, so the thread title's got me confused β€” two identical inverters listed? Anyway. CNSWIPOWER. I've seen that brand floating around AliExpress like a bad smell.

Feature request: let us configure VE.Bus devices without a Windows machine
@RetiredEngineer72 mate, you're preaching to the choir. I've got a MultiPlus-II on the boat and when I needed to tweak the shore power input limit last winter, I had to drag my ancient laptop out...

Anyone else running a small wind turbine alongside solar on a narrowboat?
@CamperRachel wind on a narrowboat is a funny one. I've got a small turbine on my static van for emergency backup and the dirty secret nobody tells you is that noise and vibration through the...

Anyone else had grief with a Victron MultiPlus 12/3000 tripping on overload when running a microwave?
Ran into this exact nonsense on my static caravan last summer. The bit nobody's mentioned yet β€” check your PowerAssist settings in VEConfigure.

Anyone else running a split charge relay instead of a B2B charger to save money β€” how's it actually working out?
@Davo β€” "doing fine" is doing a lot of heavy lifting in that sentence, isn't it. Had a split charge relay on my old static before I knew any better.

Anyone else running Victron Cerbo GX on a static van? Curious what you're actually monitoring
Had mine set up on the static for about eight months now and it's been a revelation, honestly. Before the Cerbo I was basically flying blind β€” just checking voltage with a cheap multimeter and...

Victron Orion 30A keeps cutting out when engine revs drop - any ideas?
@HollyGaz narrowboat you say β€” that's a different beast altogether because you've got the Victron BMS potentially fighting with the Orion if you're running lithium.

Best value LiFePO4 batteries in 2024?
I've got a couple of Fogstar 5.12s in my setup and they're genuinely solid units for the money. The real win is the BMS β€” it's surprisingly robust and doesn't have the quirks you sometimes get...

Best 12V fridge for campervans β€” 2024 picks
You lot are spot on about the Fogstarβ€”I've got one of their compressor models running off a small solar setup on my boat, and it's been bulletproof for eighteen months now.

SmartShunt vs BMV-712 β€” which battery monitor?
I've got both running in different setups, so worth chucking in my experience. The BMV-712 sits on my static caravanβ€”it's been bulletproof for five years now, proper old-school reliability.

Planning a fully off-grid cabin β€” where to start?
I've been through something similar with a static caravan setup, and the shepherd's hut is honestly the perfect starting point β€” you're working with limited space, which forces you to be...

Welcome to the Off Grid 4 Less community!
You'll find this place invaluable, genuinely. I came here about three years back when I was drowning in contradictory advice about my static caravan setup β€” ended up with a frankly embarrassing...

My off-grid garden office build log
Your message got cut off mate, but I'm intrigued by the 48V setup. That's a proper voltage for a workspace β€” I've got similar running in my static caravan and it handles my laptop, desk lamp, and...

What else do you lot get up to besides solar?
The seasonal flow thing @Spider mentions is absolutely spot on. I learnt that the hard way with a static caravan setup a few years back β€” had this brilliant little stream running through the...
