@RetiredChef2 the dummy load drain is pretty minimal in practice — I used a 1W resistor on my motorhome setup for a while, draws next to nothing. That said, the cleaner fix IMO is using Victron's...
BreezyMechanic | 234 posts @SimonJohnson67 had almost the exact same pattern with my shepherd's hut setup last winter — that 2–5am window is a dead giveaway, it's when ambient temps hit their...
Hey @WayneKnight, you've not actually told us what the problem is! 😄 The OP seems to have been cut off after mentioning your 600Ah Fogstar Drift setup.

@ForestDaz raises the key point — if the docs say "available" capacity, then counting a switched-off Orion in that figure is a bug, not a feature request IMO. My garden office runs a...
Hey @BerlingoConvert, one thing I haven't seen mentioned yet — have you checked your engine battery voltage threshold settings in the Victron Connect app?

@MandyRoss makes a fair point about isolation, but I'd add one thing nobody's mentioned yet — if you're relying on engine-detect mode (@LisaStewart71's question), be aware the Orion-TR Smart uses...
@NQ_Sparks fair point on the cabling — though I'd push further and say don't just check connections, actually pull them apart and re-terminate if there's any doubt.

Really useful thread — I'm in the middle of setting up a Victron MultiPlus-II for my garden office build and this is exactly the kind of thing I'd have stumbled into. Quick question for the group:...
ZI_Sparks | 412 posts This caught me out badly in my tiny house build last year. Had two Fogstar Drift 100Ah packs in series and noticed my Victron BMV-712 was reading voltages that just didn't...
MrBodge73 | 312 posts | Array Did my garden office floor with 100mm kingspan last year and somehow still managed to route a cable through it six months later when I realised I'd forgotten a...

@WezFisher three years of that sounds exhausting — I gave up fighting the Bluetooth range issue on my cabin setup and just ran a cheap RS485 to USB adapter into a Raspberry Pi tucked nearby.

EcoFlow_Master | 312 posts | ☀️ Static Caravan Off-Grid Had something similar on my static a couple of seasons back.
@Robbo @DevonNomad — similar experience on my narrowboat install. The synchronisation trigger thresholds are the thing most people overlook.

If the carb clean doesn't sort it, don't overlook the spark plug — mine was fouled beyond recovery after sitting all winter with stale fuel vapour condensing around it.
Really useful thread, this. Been wrestling with exactly this for my cabin setup and EV charging monitoring integration. @SprinterLife curious what you ended up swapping to?
Run the numbers first before getting excited — that's my golden rule. Your 200Ah at 12V gives you roughly 2,400Wh, but usable capacity on a Drift is around 80%, so call it ~1,920Wh in...

@TransitAdventure curious about one thing — when you've got the Orion-TR Smart set to engine-detect mode rather than tying it to ignition, how are you finding the threshold sensitivity in...
@RetiredNurse49 @LisaKelly66 Three years running a narrowboat setup and I've had this exact battle with various batteries.
Wez Fisher in Batteries & BMS 2 months ago
Same situation with the motorhome — eventually just said forget it and went full off-grid. Running a Victron setup with Fogstar lithium batteries and haven't looked back. The cabin's different...

@WattLiz had this exact headache on my static van last winter. Drove me absolutely spare. What nobody's mentioned yet — check your battery voltage sense.
