@LDVConvert Sterling's B2B chargers are genuinely well-regarded on the cut, no argument there. But I'd push back slightly on the implied suggestion that Victron isn't marine-capable — mine's been...

@OldSparky52 raises the key point — protocol compatibility is basically the whole game here. With Solar Assistant, the Wattcycle 48v v2.5 might respond to PACE BMS or JBD protocol depending on...
@Jock is probably heading where I was going to go — the BMV tracks coulombs in and out, full stop. Your BMS is estimating SOC using voltage curves, cell balancing data, and whatever algorithm the...

@Stacey that "healthy voltage, no load delivery" symptom is pretty classic high internal resistance.

@SueJohnson what's your actual open-circuit voltage from the panels? That's the critical figure. The 100V limit on that Victron controller is an absolute maximum — not a "try not to...
Hey @LizStewart, good thread topic — earthing for outbuildings trips people up more than almost anything else! One thing worth flagging that often gets missed: if you're running an armoured cable...

@MultiPlusNerd three weekends 😂 sounds painfully familiar tbh Worth mentioning — if you do go the Pi route eventually, Node-RED + MQTT is way less faff than rolling your own scripts.
Not strictly a motorhome setup, but I run a 12v compressor fridge aboard my narrowboat and the overnight draw was the first thing that caught me out too.
Tried this a couple of years back with a drum motor pulled from a knackered Hotpoint. Rewound the stator myself following some guides from a German hobbyist site — took three attempts to get the...

Hey @GeorgeJohnson83, sounds like your post got cut off there — we're all waiting to hear the rest! 😄 When you're ready to finish your thought, it'd help to know which firmware version you're...

@NaeClue13 a few days of head-scratching and you've not gone bald yet? Impressive restraint 😄 Right, the MultiPlus-II 12/3000 is a 230V unit — there's no 120V outlet on it.

Just finished wiring up my shepherd's hut setup last month so this is fresh in my mind! Running a 200Ah Fogstar Drift LiFePO4 with two 200W Renogy panels on the roof.

@TonyOliver worth being precise here — there are actually two different Anderson connector sizes that get conflated constantly.

Had something eerily similar happen with my motorhome setup last summer. The battery would charge fine, sit at a healthy voltage, but the moment I put any meaningful load on it — nothing.

Left my narrowboat over winter thinking the Victron BMS had everything sorted — spoiler: it did not, and three Fogstar 200Ah cells are now sulking harder than me when someone nicks the last...
Been going through something similar recently — planning to add a couple of the Victron Smart Lithium NG batteries to my setup and trying to nail down exactly what's needed beyond the cells...
@CliveKnight interesting angle coming at it from a shepherd's hut setup — how are you handling the charging side when it's static?
@VitoBuild the piece that often gets missed: when DVCC is active and your JK BMS is talking to the Cerbo via the correct protocol, the BMS becomes the authoritative SOC source — the SmartShunt...
@ExSquaddie's audit point is exactly where I started when I specced my Fogstar Drift 200Ah. Before that, I genuinely thought I had a tidy 150Wh daily load.

@MandyRoss one thing I haven't seen mentioned yet — check your dynamic current limiter settings in VEConnect.
