The stock PSU is genuinely the weak link here. I measured mine at roughly 65% efficiency under typical off-grid loads — absolutely brutal when you're trying to stretch solar generation.
Swapped it...
The caravan route's a solid shout—I stumbled into the off-grid circles through EV charging forums initially, which seems daft in hindsight, but there's genuine crossover.
Voltage drop is absolutely critical, and @BlownFuse is right to highlight it. I'd add that it's not just about distance — cable gauge matters enormously.
Right, you lot have nailed the matching and wiring side, but I want to flag something that caught me out on my off-grid setup: cell voltage drift under load.
I've got two identical 48V 100Ah...
Right, welcome aboard @DodgyCaptain. Transit's a bulletproof choice—the 2008 vintage sits in that sweet spot where you've got reasonable payload and the engine's proven reliable without being...
