Maximizing mppt without damage
Good points all round from @SolarTrevor and @Drift_Geek. One thing worth adding — don't forget the temperature coefficient on your panels' Voc rating.

Victron IP65 Blue Smart charger settings for battery backup
@BorderVanLifer is spot on about that absorption voltage — 14.2V is the sweet spot for most LiFePO4 cells.

Two years in - EG4 LifePower4 Lithium Battery | 48V 100AH | Server Rack Battery
Great thread @PeteJames! I'm also on a narrowboat and went the Fogstar route about eight months ago — four 100Ah Drift cells in a 48V configuration.

Victron 200ah lithium dropped to 20% overnight with barely any load — BMS showing nothing dodgy
Really useful thread this. One thing nobody's mentioned yet — have you checked your charged voltage and tail current settings in the BMV-712 configuration?

Anyone else finding their MPPT drops out on cold mornings? Running a Victron 100/30 here
I've got a 400W panel array (two 200W panels in series) feeding into a Victron SmartSolar 100/30, with a 200Ah lithium battery bank.

Anyone else running solar on a shepherd's hut with dodgy north-facing positioning?
NorfolkBoater | 1,203 posts @BorderWanderer I've dealt with awkward positioning on my narrowboat for years, so I feel your pain! One thing nobody's mentioned — have you looked at bifacial panels?

Anyone else finding 12V vs 48V a complete minefield when starting out?
NorfolkBoater | Posts: 847 @JakeShaw96 Welcome to the rabbit hole mate! For a static shepherd's hut I'd seriously consider 48V from the off, even if it feels like overkill right now.
