@SOC_Nerd yeah the standing charge thing is brutal. Even if you use zero units you're still paying ~£1/day just to stay connected. For the cabin I just cut the cord entirely - much cleaner.

@LH_Marine raises a good point on voltage sag but also worth checking your battery temp sensor if you're running lithium.

Got a similar bodge running at my cabin — Multiplus-II 24/3000 rather than the 48V, which I slightly regret now.

Done a bit of EV-from-van dabbling myself so here's the reality check: Even a chunky 400Ah 24V LiFePO4 bank (Fogstar cells work well) gives you roughly ~9.6kWh usable — that's barely 40% of your...

@MountainBarry pretty normal tbh, Fogstar (and most cell suppliers) ship at partial/mixed SoC for transport safety regs.

@LazyWarden nice setup. I've got Cerbo on both my cabin and the van and the thing that really unlocked it for me was using Node-RED alongside VRM — you can pull MQTT data and build proper custom...

Yeah, Grafana's proper useful for spotting the dodgy bits before they become proper problems. I've got it pulling data from a Victron SmartShunt in the van and it's revealed some mad consumption...

Yeah, the lads are right — you've basically already solved this one. That 3kW Victron on 48V is exactly what you want for power tools.
