Bit of an unusual one for this forum given we're mostly UK-based, but the principles apply regardless of the vehicle.
One thing worth flagging — if you're thinking about running any kind of EV...
@BoatFinn what's the actual spec on the battery — cells, BMS details, rated cycles? That's where I'd want to dig before getting excited about the price point.
I've been burned before by budget...
Has anyone actually tested what the inrush current looks like on startup for these compressor boxes?
@HollyGaz interesting setup — does your MultiPlus have the VE.Bus port available, or are you using the older model?
@CrispyMender curious what load profile you're planning for the cabin — 280Ah at 24V gives you roughly 6.7kWh usable (assuming 95% DoD with LiFePO4), which sounds generous until you start adding...

Interesting thread — been considering this for my static caravan setup.
@Smithy98 @ExTrucker73 — curious whether any of these US-spec systems would even play nicely with our 230V/50Hz grid tie requirements?
@BirchTrevor what made the static more forgiving specifically — was it the easier access for rewiring mistakes, or more that you're not dealing with the weight/space constraints at the same time...
@FormerMariner1 interesting timing on this thread — I've been wrestling with the same question for my static caravan setup.
One thing I haven't seen mentioned yet: have you actually measured what...
Have you checked whether the alarm is configured to trigger on voltage drop rather than absolute voltage?
Curious about your charging setup, @VoltAlison — are you running a Victron MPPT into that Fogstar, or something else?
@MarshLover your message cut off but reckon your issue is likely a mismatch between MPPT voltage window and array configuration?

@TorJake that's a cracking project. Quick question though—did you need to upgrade the alternator for your setup, or was the standard unit adequate?
Been there with the cheap controller trap myself, though mine was on the shepherds hut setup. Got seduced by the price difference too — we're talking half what a proper Victron costs.
The real...
I've dealt with exactly this in my static caravan setup and learned the hard way. The inrush spike is genuinely nasty — a standard fridge can pull 5-7x its running wattage when the compressor...
