Beyond the firmware and wiring points already covered, something that bit me hard last winter was the battery temperature compensation settings in the Victron.
Been thinking about this setup lately and wondered if anyone's had hands-on experience with it. I'm looking at running a Victron Multiplus-II in my cabin to handle the main battery bank and solar...
Had this exact issue in my shepherd's hut setup last summer. Multiplus II kept jumping to float after maybe 2-3 hours of bulk even though the Fogstar Drift LiFePO4 wasn't anywhere near...
Been running a Pi 4 with Venus OS Large for about 18 months now and honestly it's transformed how I manage the system.
Classic narrowboat problem this — shore power disappears at a marina and suddenly your whole system throws a tantrum like a toddler whose biscuit fell on the floor. My Victron Multiplus-II does...
There are a few layers to unpick here, and I suspect the question might be coming from a North American context — because in the UK we're working with 230V as our standard mains voltage, which...
Been running a similar setup on my boat for about 18 months now — MultiPlus-II 48/3000 with a Fogstar Drift 48V LiFePO4 pack, no solar, just shore power charging and battery backup.
Exactly what @Spud79 said, but the flip side nobody mentions: winter will absolutely humble you, especially up here in Scotland where I'm sometimes getting 2 usable hours of generation on a grey...

@LiFePO4Nerd makes a fair point but nobody's mentioned the British weather tax — half your "surplus solar" plan evaporates the moment it's February and you've got 0.3kW dribbling in from...

So I'm in a similar boat — got a 24v panel sitting on the roof of my static and a 12v Fogstar lithium under the bed, and I'm trying to work out the best controller setup without spending a...
Had a couple of these on the narrowboat over the years — the £15-£25 units you see plastered all over Amazon and eBay with optimistic specs printed on the side. Honestly?

Running a small chest freezer in my static caravan off a 200Ah LiFePO4 (Fogstar Drift) and genuinely not sure if I've got enough capacity to get through the night without killing the battery. The...

@BoxerAdventure that's actually a really good shout — did you get anywhere with them? Curious whether they have any consolidated docs or just point you back to Victron's website anyway. I've got a...
Got caught out exactly the same way in my van — turns out my Victron BMV battery monitor was the most useful £80 I ever spent, showed me I was haemorrhaging power through a cheap Chinese inverter...
Running a small chest freezer on my narrowboat at the mo, and I'm trying to work out if my setup is actually viable before I commit to stocking it with a month's worth of sausages. Got a 200Ah...

@GlenSimon that's exactly what's running through my head — my narrowboat's emergency backup is literally what keeps me from becoming an unlit hazard on the canal at 2am, so I'm not gambling on a...

@LiFePO4Nerd nailed it with the canary thing. My cabin setup runs a 3kW kettle no bother — but it's the combination that gets people. Kettle plus toaster plus someone plugging in a laptop?

@SmartSolarMaster raises a good point about the remote switch — worth checking the two-pin connector on the control board too, not just the switch itself.
Not really my patch — my experience stops at UK G98/G99 and a pair of Victron Multiplus-II 48/3000s in the cabin. That said, the principle of three-phase balancing with Multiplus-II units is...
@EcoFlow_Gal leaving us all hanging there — classic forum cliffhanger. One thing worth flagging from my narrowboat experience running parallel Victron kit: phase synchronisation timing on startup...
