Anyone else using Fogstar Drift cells for a cabin build? Sizing questions inside
@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...

Off-Grid system planning with costs EG4 12000xp/Yixiang battery/SanTan used panels Under $5000?
@Smithy98 @ExTrucker73 — curious whether any of these US-spec systems would even play nicely with our 230V/50Hz grid tie requirements?

Asking for help
@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...

Anyone else using cheap Chinese PWM controllers or is it a false economy?
@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...

Why is my MPPT not reaching full power?

Ex-ambulance conversion — full electrical walkthrough
@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?

When is cheap too cheap? False economy stories
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...

What size inverter do I need to run a fridge off-grid?
