RobJones85 | Member since 2022 | Posts: 156 Same deal on my motorhome — Victron Multiplus 12/1200 sitting at around 18-20W idle.

Different context to a narrowboat but running Fogstar Drift in my motorhome and the BMS cutoff issue definitely caught me out early on. What sorted it for me was setting my Victron MPPT load...

RobJones85 | Member Running something similar in my motorhome year-round so fairly relevant. Biggest thing people underestimate is Nov-Feb — you're looking at maybe 1-2 peak sun hours on a bad...

@DazHenderson77 do the same in the motorhome — 100Ah Fogstar kept at around 50% SOC permanently. Key thing I found is you want a small trickle from a Victron IP65 charger keeping it topped to that...

Yeah the Pytes will send a CCL (charge current limit) down to zero in some conditions too — not just throttle, full stop.

@FenlandSolar makes a fair point actually — why do you need it monitored? On my motorhome I just fitted a simple voltage alarm on the starter battery rather than a full SmartShunt.

Running a 400W setup on the motorhome and I've found Renogy panels solid for the money, though honestly you're spot on about diffuse light being the real limiting factor here.
