Great thread @Davo2. One thing worth considering if you haven't already — look into whether your inverter/charger has a generator input setting you can tweak.

If your alternator's struggling to hold voltage under a 30A draw, just tell the Orion it's on a diet — drop the input current limit in VictronConnect and let the alternator catch its breath before...

Nessa | 312 posts Worth flagging something nobody's mentioned yet — thermal management in a static caravan can be brutal, especially in North Wales winters.

Nothing to do with your MPPT being thick — LiFePO4 voltage curves go flatter than my nan's soufflé in the cold, so the controller genuinely can't tell 80% from 40% just from voltage alone.

Hey @BazKnight57, one thing that made a big difference for me was making sure the battery capacity and Peukert settings in VEConfigure are spot on for your specific cells — Gobel LFP behaves quite...

Been experimenting with trickle charging my Leaf from the cabin setup this summer. Running a 2.4kW Victron Multiplus-II off a 400Ah Fogstar lithium bank with about 1.2kW of panels on the roof.

SarahClark75 | 89 posts @RobWebb59 Just to add a practical tip — a small self-regulating heating pad designed for pipes works brilliantly for van battery boxes.

Been running a 280Ah LiFePO4 pack I built myself over the winter and decided to give one of those generic 4S 100A BMS boards a proper go rather than splashing out on a Daly or JBD straight away.

VictronMaster | Posts: 2,156 | Location: Array One thing nobody's mentioned yet: with LiFePO4, the split-charge relay can actually damage your alternator.

Just finished wiring up my system in a converted horsebox — 400Ah of lithium (4x 100Ah Winston cells), a Victron SmartSolar 100/30 MPPT and a Giandel 2000W pure sine inverter.

@BrianKnight86 Worth noting that the BMS disconnect under load is what kills alternators — when the BMS trips, the alternator suddenly loses its load and the voltage spike can fry the regulator...

DonnaMurray | Posts: 134 @DerekDixon I've gone through this exact debate for my shepherd's hut and ended up going straight to Fogstar Drift lithium — no regrets.

@JakeShaw96 classic rookie tax — we've all paid it, mine was confidently wiring a 100Ah lead-acid into a shepherd's hut and wondering why it gave up the ghost every February like a seasonal...

@OffGridFreak the maths is the brutal bit — 1.2kW array into a 5kWh bank doesn't leave much headroom once you factor in cloudy days.

ExpertBuild | 312 posts @SaltyMaker solid foundation you've already got there. The hybrid question really comes down to one thing — do you have grid access at the site, even occasionally?

@T6Life had almost the same on my boat last summer — turned out to be partial shading I'd completely overlooked.
