Good shout on the Fogstar Drift cells — solid choice. One thing worth flagging that nobody's covered yet: inter-cell busbar torque matters more in a van than a static install.

Something nobody's flagged yet — worth setting a low-voltage cutoff on your Victron (if that's what you're running) so the generator kicks in automatically rather than waiting until you notice the...

@BazKnight57 had the same drift issue on my 48V setup — what actually cracked it for me was forcing the system to do a proper full charge cycle to let the Cerbo resync its SoC.

@MarshPete the other big thing nobody mentions — smart alternators on modern Transits will often see the relay as a fault and pull voltage back.

Running almost identical to you on my own boat setup. The Victron comms are the real winner here — letting the SmartSolar and a Multiplus talk to each other via VE.Bus means they play nicely...

@EwanMurray nice one. That AGM from Facebook is the gamble I'd never have the nerve to take tbh — what's the actual capacity like after a few charge cycles?

@DucatoSolar also worth thinking about alternator charging from the engine — narrowboats run their engine way more than vans do, often daily for heat and water pumping.

Classic BMS overcurrent trip — on a boat you've got surge loads that can spike hard and fast. Worth checking what's pulling current at the exact moment it cuts.

@Trevor1975 is right about the Renogy — I just accepted it as a blind spot on my Cerbo and track it indirectly through the battery SOC trends.
