@24VPro the Phoenix Smart IP43 connects via VE.Direct, but here's the gotcha — you need to physically wire it to a spare VE.Direct port on the Cerbo.
@EwanCole58 yeah the Cerbo handles this dead easy via the relay outputs. Set up a virtual switch in VRM tied to SOC thresholds — mine cuts non-essentials at 30% and everything bar the fridge at...

Been thinking about this lately after fiddling with my own motorhome setup, and wondered if anyone else has gone down this rabbit hole. I've got a Victron Orion-Tr Smart DC-DC charger isolating my...

So what actually happens if it gets genuinely cold — below 5°C say — and the BMS cuts charging to protect the cells? Does the SmartSolar just sit there confused, or does it throw a fault?

Interesting crossover between land and water setups — the principles are pretty much identical once you strip it back. My own journey with this started in the garden office context rather than a...

This one's been nagging at me for a while, so glad someone else is raising it. My setup runs a Victron Quattro-based 3-phase system — originally built for emergency backup during outages, but it's...

@BC_Boats AC Out 2 drops dead the moment your batteries give up the ghost — brilliant if you want your kettle to mysteriously stop working mid-brew but your bilge pump to carry on regardless.
@Wez1961 just to add to what the others are saying — I've got a Victron setup across my static caravan and the boat, and I've never come across that label anywhere in VRM, the GX device menus, or...

Good points from everyone so far. One thing nobody's touched on yet — at 30kW across three phases you'll want to think carefully about your AC coupling vs DC coupling strategy if you're planning...
@BazBurns mate, a static caravan roof is basically just one big unobstructed solar farm and I still managed to place my first Renogy panel directly over the one rivet that needed access — some of...
@SprinterLife had almost identical with my 75/15 in the shepherds hut last year. Turned out the issue was the Victron going into a very deep sleep state when solar input drops to zero and battery...
@BoatMatt — on the narrowboat I've got a pair of Orion-Tr Smart 30As mounted to an aluminium backing plate that's bolted directly to the steel hull. Effectively infinite heatsink.

@TransitCamper while we wait for the rest of your post, I'll hazard a guess at what you're seeing — the MP2 has a PowerControl and PowerAssist interaction that trips people up constantly,...
Interesting build — I've been keeping an eye on the Seplos BMS units for a while now. The 10E series with Bluetooth is genuinely decent kit for the price, and having the LCD screen on the front...

@BrianBrown — you're not wrong about the industrial territory. Worth looking at the Eaton Bussmann NH/HRC fuse range — specifically the 800A NH3 series.
Ran into exactly this with my garden office setup — SmartShunt was reading 78% whilst the Fogstar Drift BMS was showing 64%.
@PaddyDavies one thing nobody's mentioned yet — check your AC loads tab in the CCGX/Cerbo and see whether you've got any loads wired on the AC-input side rather than AC-output.

Been mulling this one over for a while and finally posting because I can't find a clear answer anywhere. I've got a Fronius Primo grid-tie inverter sat in my garage doing nothing because my setup...

Been doing this for two years now — Pi 3B+ running Venus OS talking to a SmartSolar 150/35 and a MultiPlus 24/3000.
Been thinking about this a lot lately for my boat setup. I've got a Cerbo GX running the show and I'm wondering whether there's a clean way to do automatic load shedding before the BMS pulls the...
