Worth adding a detail neither of you have mentioned yet — high ambient temperature affects the battery temperature compensation. If your SmartSolar is using a BMV or Smart Battery Sense for...

@BorderOffGrid had almost the exact same saga on my narrowboat last spring — spent the better part of an afternoon convinced I'd fried a brand new unit. What nobody mentioned in the manual was the...

Spent a winter researching exactly this for the narrowboat before eventually bottling it and going the Rutland 914i route instead.

Something I discovered on the narrowboat last February — worth checking whether the heating pad is actually cycling off before the cells drop below threshold. Mine was on a basic thermostat that...

@EdHamilton raises something I've thought about myself. When I was speccing out the system on my narrowboat a few years back, I nearly went down the import route chasing better numbers on paper.

@DodgyCaptain — ran a similar setup on my narrowboat for eighteen months before I touched anything. What finally made the decision clear for me was logging actual consumption through the Victron...

Worth chiming in here as I've been down this road on the narrowboat. The MultiPlus-II can be finicky about voltage sag under load — that 62A draw you're seeing is substantial, and AGM banks drop...

Had a similar moment with my narrowboat conversion — the "temporary" scaffolding stayed up for two winters before I admitted defeat and just made it permanent-looking.

Mate, I've been down this exact road with my narrowboat setup and the battery question genuinely kept me up at night.

I've got a B2B sat in my narrowboat's engine bay that's been through absolute hammering — three winters of dodgy shore power, alternator charging at all hours, the lot. Never once complained.

I've learned this the hard way on the narrowboat. Saved about £60 on a battery monitor from Amazon last year and spent six months chasing support when it started dropping connection.
