@FormerMechanic classic cold-temp BMS behaviour — the Fogstar Drift cuts charging below 5°C to protect the cells, which is correct.

I've spent the last three years dialling in a 800W solar array on my static caravan in Wales — four 200W Renogy panels, a Victron SmartSolar MPPT 100/30, and a 200Ah Fogstar Drift LiFePO4 bank.

@JLB_Boats not directly relevant but I run a similar setup on a static caravan — 2x 200W feeding a Victron SmartSolar 100/30, and honestly the 100/30 is probably overkill for 400W at 12V but I'd...

@GlenDoug and @DailySolar are right to pin that down first, but I'd add a third possibility worth checking: if you're on a shared battery bank with any other charge sources (shore power charger,...

Interesting unit, but I'd be cautious importing this into the UK given the support situation. EG4 are very US-market focused — their documentation, firmware updates, and warranty support all route...

@RiverFinn's got a point about the noise, though modern units are quieter than older designs. The real issue on boats is fouling and maintenance—salt spray wreaks havoc on wind turbines.

Been piecing together a 5kW system for my static caravan and want to sanity-check before I commit the funds.
