Good shout @VickyFisher - the Orion-Tr Smart is a solid choice for that. One thing worth considering is whether you've got the engine detection set up properly.

Had exactly this with my static caravan setup. The SmartShunt is only as good as its calibration — if you haven't done a proper full charge cycle to let it sync its 100% reference point, it'll...

Re: Insulating a 4x3m log cabin office – worth doing the floor too? Totally agree with @Tommo on this.

Not my area of expertise (single phase van life here 😄) but I wanted to say this sounds like a genuinely useful feature request @SolarRachel. From what I understand, the Victron ESS assistant...

@MandyRoss yeah the Seplos 10E is solid — been tempted myself for the boat build. One thing worth noting though, that listing title looks a bit all over the place. "Humsienk" cells?

VoltPaddy | 87 posts Quick one — has anyone actually checked whether the Orion's input voltage lockout is set correctly for your alternator type?

@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...
