Been tracking this thread closely as I've had similar grief with my setup in the Scottish Highlands.
Yeah, @LH_Marine's spot on about the CANbus issue. Seen this loads with budget packs. Quick wins before you write it off: Check if your BMS has a manual CANbus config—some ZYC variants let you...

Been wrestling with this exact setup on my boat for the past few months, so keen to hear how others are tackling it. I've got the Multiplus-2 GX paired with two US5000s, and the battery management...
Been following the recent regulatory shifts around three-phase installations, and I'm curious how others are tackling this with the newer Multiplus II hardware.
Been following the technical specs on this sort of setup and have to say, the three-phase configuration makes a lot of sense for larger off-grid installations.
Just spotted this on the Humseink site and the pricing's mental — nearly 50% off is quite the deal for 16kWh LiFePO4.

Been wrestling with this exact problem in my van setup. I've got a Victron GX device (Cerbo GX actually, bit overkill but grabbed it on offer) talking to a Multiplus II through VE.can, and I'm...
Yeah, the elephant in the room is battery capacity—you can bodge together panels and an inverter for peanuts, but a decent lithium setup that won't die after three cloudy days costs more than the...

That overnight drain is likely your BMS itself—LiFePO₄ packs draw 0.5-2% capacity per 24hrs in standby depending on the quality of the management board.
Right, good thread this. I'd add that the critical bit everyone's dancing around is BMS synchronisation.
Had this exact headache with my shepherd's hut setup out in the sticks. Victron's monitoring is brilliant when you've got signal, but absolute nightmare when you're borderline. Few things I've...
Yeah, had this exact problem last summer. Water got into my panel connectors somehow and caused intermittent faults with the whole system.

Has anyone else gone hybrid on a shepherd's hut setup? I've been running pure solar for two years now and it's been brilliant, but winter generation is absolutely dire.
Got 200W on my static caravan roof and it barely keeps the fridge running in winter—can't imagine the nightmare on a narrowboat where you're moving the bloody thing about.
Right, I've been down this road myself with my Victron setup out here, and it's genuinely one of the trickier bits when you're going off-grid.
Had this exact nonsense on my narrowboat. The Multiplus is doing its job — protecting your battery from deep discharge — but the factory LVD settings are too aggressive for real-world use. Your...
Been running a pair of Phoenix inverters on my narrowboat for the better part of four years now — a 1600VA for auxiliary loads and a 3000VA for the main system — so this PE-N bridging question's...
Tried going cheap on my static caravan setup years ago — burned through two dodgy units in eighteen months. What's your actual battery bank, @OffGridFreak?
Good call from @WD40Wizard78 and @SamReid on the connectors and multimeter—those basics really do save headaches.
I've been running into something similar with my narrowboat setup, and I reckon it's worth unpacking here because it's caught me out twice now. The issue seems to be that the BMZ needs sufficient...
