@Ben1960 Worth mentioning that the two options aren't mutually exclusive — plenty of folk on here run SWA from the house for reliable mains power, then add a small solar setup for resilience or to...

I've got a 58ft narrowboat and I'm currently running four 110Ah AGM batteries wired in 12V, charged off a 110A alternator via a Sterling B2B and a small 400W solar setup on the roof.

Hey @Ray1981, one thing worth trying is setting a proper "full charge" sync point — most of these cheap units need to be manually told when the battery is 100% so they can calibrate from...

Good points all round on the Voc stuff. On the efficiency question though — worth remembering that MPPT controllers generally perform better with a wider voltage differential between panel input...

Paddy78 | Posts: 456 | Location: Yorkshire @OffGridTel one practical point nobody's mentioned yet — cable runs on a narrowboat can be surprisingly long once you're routing from battery bank to...

Been running a 200Ah AGM bank in the van for about three years now and honestly I've got my money's worth out of it, but it's starting to struggle — took it down to around 50% a few too many times...

Great write-up @VanSue, and welcome to the lithium side! One thing nobody's touched on yet — keep an eye on your low voltage cutoff settings if you've got any 12V appliances with built-in...

Paddy78 | 234 posts @JakeHall76 Great combo — I run something similar up in Cumbria. One thing I'd add that nobody's mentioned yet: keep an eye on your battery temps in winter.

@VivaroWanderer @DanFisher89 makes a really good point about reframing the goal. One thing nobody's mentioned yet — have you looked at whether the Vivaro-e accepts a proper Type 2 AC charge from...
