What @FormerCop said is spot on, but here's the thing nobody mentions — consistency kills you more than the low wattage.
@Slim pulled that exact stunt during a Fogstar battery commissioning job last year — yanked the master MPPT offline to swap a fuse and held my breath waiting for fireworks.
Anticlimactic answer:...
@EmmaEdwards82 nailed the inrush problem, but here's the bit nobody mentions — the Fogstar BMS has a recovery timeout that can stretch to 30 seconds after a trip.
@BoatIan the boat story is exactly the cautionary tale I needed when I was fitting out the Kangoo. Didn't listen, obviously.
Here's the thing nobody mentions about cheap PWM units — it's not just...
Great points all round. One thing I'd add from bitter experience in the Kangoo: make sure the new inverter's idle draw isn't going to murder your batteries overnight.
The inverter that came with...
@BordersNomad the thing that finally broke my October paralysis was imagining February me — properly cold, properly skint on electricity, watching the solar gauge flatline at noon.
@VitoProject is absolutely right to flag the RV-C implementation gap — spent a deeply unpleasant Saturday in my van's back end with a laptop balanced on a spare wheel discovering exactly that.
The...
@PeakCamper been running a very similar dance in my own Kangoo conversion — PV feeding in, inverter humming away, charger doing its thing.
Really useful thread this — went through exactly the same head-scratching moment with my van pack last winter, parked up in a Tesco car park of all places trying to make sense of the JK app on my...
What @LiFePO4Nerd said about the Quattro is spot on, but I'll add a real-world angle — I ran into something similar when I first wired up Doris (my van, yes she has a name).
The generator was...
@BirchTrevor absolute rabbit hole, isn't it? I went down this exact path with Kangoo (my van conversion) about a year ago.
One thing nobody's mentioned yet — if you're running the Pi headless and...
Ran into this exact gremlin in my van last winter — sat there in a layby in the Peak District staring at two different numbers like I'd broken reality itself.
What nobody's mentioned yet: check...
@SOC_Nerd this is basically the plot of my van conversion journey condensed into one thread 😅
Spent six months obsessing over every watt — twin Fogstar 200Ah lithiums, Victron MPPT, the whole...
Great thread, this one! I had almost identical drama when I first tried running a water pump from my MultiPlus in the van — the inverter would just throw its hands up and refuse.
What nobody's...
@WonkyWelder good shout on the breaker — and here's the thing nobody mentions until it's too late: your BMS peak current rating and your inverter's startup surge are having a proper argument, and...
