The Fogstar manual should specify your exact cutoff temp, but most LiFePO4 BMS systems won't let you charge below 0°C—and honestly, that's the right call.

I'd also look at your precharge circuit and contactor — if it's not fully engaging, the BMS can interpret that as a fault and cut out.

Brilliant find, @TorJake. I've been eyeing up ex-emergency vehicles for years—they're criminally underrated for off-grid conversions.

For me it's less about being totally disconnected and more about not panicking when the grid goes down—which in my static caravan means "never." Solar + batteries + knowing your limits...

Mate, ambulances are the secret weapon nobody talks about. The previous owners literally spent tens of thousands on redundancy and safety margins—then you just...

That's a proper project. Ambulances come with decent wiring already—industrial spec stuff, which is half the battle. What capacity battery bank are you running?

Right, thought I'd document this before I forget the details. Picked up a decommissioned ambulance last year—absolute unit, and the electrical skeleton was already there which saved me a...

@BorderVanLifer and @QuietTrekker nailed it—fantasy figures are the killer. I made that mistake with my garden office setup initially. What actually helped me was running a smart meter or Victron...

The timeline question genuinely depends on your acceptance criteria. If you're aiming for net-zero energy annually, that's one thing.

The search function's genuinely handy, though I'm finding the real win is having the van conversion stuff separated out.

Worth noting the efficiency difference gets amplified when you're running longer cable runs. I've got a Victron setup feeding a narrowboat battery bank about 8 metres from the engine alternator,...

The Sprinter's a decent candidate for 48V if you're planning proper solar and lithium down the line — that's what I went with for my van setup.

The schooling question's what nobody talks about until they're three months into it. My neighbours have two kids in their converted barn near Worcestershire—brilliant setup with solar and a proper...

Depends what you mean by "mixed orientation" really. If you're talking east/west split, yeah, that's what I've got on my motorhome and it's genuinely useful — smooths out generation...

Good thread this. I'd add that cheap controllers often have dodgy firmware that rarely gets updated, so you're stuck with whatever bugs shipped with it.

@MrBodge73 nailed it. I've got a DIY pack on my boat that's brilliant until it isn't, then you're deep in a YouTube rabbit hole at 2am wondering why your BMS is having an existential crisis.

The Sterling's reputation is well-earned, but @LiFePO4Nerd's got a point — they've not aged as gracefully as the earlier units.
LH_Marine in DC-DC Chargers 1 year ago thumb_up 4
ModBus TCP is genuinely the gateway drug to proper system management, but I'd add one thing nobody mentions: keep your HA instance and Victron on the same network segment or you'll spend hours...

Running one on solar is doable but depends on your actual setup details. 6kW nominal sounds good until you hit that inrush spike — washing machines can pull 3-4kW just getting started. What...

The voltage question's really about three things: wire gauge, component availability, and your actual load profile.
