@VitoBuild yeah the Cerbo boot sequence is a proper pain point that not many people talk about. Had this exact issue on my motorhome build - Multiplus-II comes online before the Cerbo has fully...

Bit of an odd one this, and something I've been mulling over with my own setup on the Sprinter. Running a Centaur 12/60 from shore power to top up the starter battery whilst simultaneously...
Worth noting you're probably in the wrong place mate — this forum's pretty UK-centric so specs, tariffs and grid rules won't really apply to your situation.
George1975 | 203 posts | 🔌 EV & Off-Grid Pi is brilliant but I'll be honest — when I was setting up the shepherd's hut I tried the full InfluxDB/Grafana stack and spent three weekends...
@Clive1999 started a list, lost power, and somehow that's still more useful than half the completed posts on here. For what it's worth from someone who's had a static van, a garden office, and a...
Foggy80 | Posts: 847 @MoorKev that third one lying about percentages is actually the worst outcome of the three if you ask me — at least you know when something's dead.

Been running exactly this setup for about eight months now across my shepherd's hut system and honestly it's transformed how I understand my energy use. I've got a Raspberry Pi 4 pulling data from...
Been meaning to ask about this for a while so might as well stick it here. I've got a Victron SmartSolar 75/15 on my static caravan and I want to use the load output to switch a 12V solenoid valve...
Been doing this in my motorhome for three years — Pi Zero 2 W if you're tight on space/budget, runs VenusOS absolutely fine and sips maybe 1.2W versus the Cerbo's ~3W, which matters when you're...
Don't forget a well-stuffed freezer is basically a self-insulating brick — mine barely blinks overnight on a 200Ah Victron setup once it's pre-chilled properly.

Had this exact scare on my boat last year. The IP22 is solid kit but the default AGM profile will push hard if your battery's already warm or the sensor's not connected. Worth grabbing the temp...
Running into something similar with my own setup and curious what others have done about it. I've got a Victron Multiplus-II with a 20kWh Fogstar battery bank and I've been wrestling with the EVCS...

Been down this exact rabbit hole with my shepherd's hut build, so figured it was worth starting a proper thread on it. I'm running two DIY LiFePO4 banks (280Ah cells from Docan, paired with JK BMS...
@MarineAlan the elephant in the room nobody's mentioned yet: what's your charging source? Two 200Ah lithium packs in parallel is lovely until you're trying to fill them with a 20A solar controller...

Been wrestling with something similar on my van build that I've since scaled up to a static off-grid setup, and I reckon this deserves more attention than it gets. Running a Victron Multiplus-II...

RetiredChef26 | 847 posts | ⚡ Solar & Storage Enthusiast @XU_VanLife Your post got cut off mate, but I think I can guess where this is going!
Had this exact issue on my van build last summer. Victron 100/30 was hitting float after barely 2 hours on a decent sunny day — batteries nowhere near full. Turned out my absorption voltage was...
Mate, 200V open-circuit from 11 panels in series going into an AIO not rated for that input is basically a very expensive way to turn your trailer into a bonfire.
Good question and something I spent a fair bit of time puzzling over when I oversized the array on my narrowboat. The MPPT is the key bit here — it doesn't "switch off" the panels, it...
@Moorey44 worth adding from a marine perspective — boats require isolated DC systems by convention (and often by regulation), so I've got some experience with floating setups.
