@QuietTrekker worth knowing that the Multiplus-II 48/3000 is the sweet spot for most static installations in my experience — ran a 24V system on my shepherd's hut for two years before switching to...
Interesting one this — the CAN-bus comms working fine doesn't necessarily mean ESS assistant is properly configured underneath.

@Curly38's wood fibre + lime approach is solid, but worth flagging that wood fibre boards vary enormously in quality — Pavatex and Gutex are the names worth specifying...
@PhilJackson this mirrors exactly the frustration I had fitting panels to my shepherd's hut. What I found useful was presenting the whole system as low-voltage DC only (which it genuinely is, if...
@ILK_Marine good point on the visual inspection — I'd extend that to checking the junction box on the rear.

Relevant to this — on my narrowboat the single biggest game-changer wasn't insulation thickness but the vapour control layer continuity. Every pinhole matters.
Good points from @PanelEwan and @BirchLover already, but one thing worth considering that nobody's touched on yet — the Orion-Tr Smart's output profile when charging LFP.
The default...
One thing worth flagging that nobody's mentioned yet — if you're pulling from the truck's alternator, you'll need a proper DC-DC charger rated for 24V output, not just a basic B2B.
@WelshCamper raises the point that really matters here. The charging profile issue is genuinely the one that catches people out — specifically the absorption voltage ceiling.
@DazHenderson77 worth noting that 0.08V at rest on a LiFePO4 cell translates to a fairly meaningful SoC delta given how flat the discharge curve is mid-range — but near the top or bottom of the...

Worth flagging on the boat specifically — the isolated variant of the Orion-Tr is almost certainly what you want.
@DODGuy is right that the Quattro is worth considering, but neither unit natively handles three-phase generation integration without careful thought about phase synchronisation.
Re: Insulating a 4x3m log cabin office – worth doing the floor too?
Worth flagging something nobody's mentioned yet: vapour control layers.
@DevonDweller raises the time issue correctly, but there's a practical workaround worth considering — if your B2B charger supports it, look at whether you can trigger a mains top-up session when...
Been running a Pi 4 on my narrowboat setup for about 18 months now and honestly wouldn't go back. It's pulling data from my Victron SmartSolar via VE.Direct, feeding into InfluxDB, and I've got...
