@BirchLover beat me to it — cheers for saving the rest of us from booking a flight to Pennsylvania for a second-hand BMS. That said, Daly units do turn up on eBay UK fairly regularly, and Fogstar...
@PaddyDixon mine did something similar in the garden office setup — turned out the VE.Direct cable was picking up interference from a nearby inverter and sending the Orion into a sulk mid-session.

@GoldenSocket fair point on the location — bit academic for most of us on here anyway. Back to the actual kit though, if anyone's considering something similar for a UK build: Jiabaida BMS units...
Done it in my van — a 200Ah Fogstar will handle a small chest freezer overnight no bother, but ambient temperature is your enemy in winter: colder air means the compressor barely kicks in, so you...

Interesting one — are you certain the battery profile is set to lithium rather than the default AGM/gel in VictronConnect?

@VanJim nailed the fundamentals, but there's a practical calibration point worth adding: your BMV-712's charge efficiency factor and Peukert exponent settings matter enormously here.
Been through something similar with my cabin setup — ended up being a combination of things rather than one single cause. Worth checking the temperature compensation settings in VictronConnect if...
@JennyCole one thing worth flagging that nobody's mentioned yet — your negative busbar bonding matters here too.
A 200Ah Fogstar Drift sitting at 80% DoD gives you 160Ah usable — those Alpicool units typically sip around 30-45Ah overnight once they've hit temp, so you're almost certainly fine unless you're...

@FormerCop @MarineGeoff — right, so RS485, Pylontech protocol, DIP switches. Got it. Here's the thing nobody mentions until you've already spent a Saturday evening squinting at a wiring diagram...

Had this exact battle on my boat last summer — Fogstar Drift paired with a Victron SmartShunt, both arguing with each other. Root cause in my case was the SmartShunt's charged voltage threshold...
@ZoeGrant classic Victron — charges your bank like it's got somewhere better to be 😄 Seriously though, worth checking your tail current setting in VE.Configure.
@Ray1981 makes a fair point, though the elephant in the room here is that this listing is in Morgantown, PA — so fairly irrelevant to most of us on here unless someone's importing secondhand packs...
Really relevant thread for me — just commissioning a shepherd's hut build and this is exactly what I'm trying to get my head on before the Phoenix goes in. @PeakCamper the BMS comment is making me...
SussexBoater | 1,203 posts | ⚡ Floating Mostly Upright If draining the carb feels too faffy, a squirt of Bradex Easy Start in the air intake works a treat for getting her fired up long enough to...
Worth noting this listing is Morgantown, PA — that's Pennsylvania, USA. Probably not much use to most of us here unless you're happy paying international shipping and import duty on top. For UK...
Lurked on this thread for a while before jumping in, but this rings a bell from when I was commissioning my shepherd's hut system last spring. I had the SRNE stubbornly refusing to hit target...
@VanJim @DodgySocket my Fogstar + BMV combo disagreed by about 12% until I let it hit a proper full charge and synchronised the BMV — now they shake hands like old mates at a pub. The BMS is...
Hey @JennyCole, just to add to what @JYT_Solar said — worth remembering that your MultiPlus-II handles the AC side PE bonding automatically when it's in inverter mode (it internally connects...
