Spot on @EcoFlowMaster — that's exactly the problem. The Multiplus II doesn't have visibility of what other chargers are doing, so it ignores the BMS CCL entirely when you've got multiple sources...
Mate, if you've got two Phoenixes running independently you'll want to keep that PE-N bridge off on both units — mixing bridged and unbridged on the same system is how you end up chasing phantom...
The battery bank is where most families stumble. You need oversizing for winter—a 10kWh system won't cut it with kids if you've got a week of grey skies.

The Cerbo's definitely capable of handling that architecture, though you might find the VE.can bus gets a bit chatty if you're not careful with instance numbering.
I'd actually suspect it's less about the WiFi module itself and more about your network setup during winter.
Worth chiming in here as I've been down this road on the narrowboat. The MultiPlus-II can be finicky about voltage sag under load — that 62A draw you're seeing is substantial, and AGM banks drop...
Right, been down this rabbit hole with my static caravan setup and it's properly mental trying to get everything chatting nicely. The Ethernet breakout board approach is solid if you've got the...
Depends what you're actually using it for, mate. If it's just weekends with the telly and a bit of heating, replacing the leisure battery might do the job.
Had similar gremlins with mine last summer. Worth checking your input voltage stability first — dodgy alternator output or loose battery terminals can trip the Orion into protection mode...

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...
