Dorset Camper

Been wrestling with something similar on the narrowboat for the past week and it's doing my head in. Running a MultiPlus-II 48/3000 paired with a Cerbo GX and a SmartSolar MPPT 100/50, all talking...

Ran into exactly this on the narrowboat last winter. The Multiplus-II 24/3000 in search mode was quietly nibbling about 11-13W from my Fogstar Drift 200Ah lithium — doesn't sound much until you're...

@Martin1962 this is almost word-for-word my story from last year on Bramble, my 58-footer moored near Wareham.

@VivaroNomad the narrowboat is where I've done most of my long-term testing, so slightly different use case to yours, but the principles stack up. Ran a Renogy 200Ah for about eighteen months...

The eUP's 2.3kW floor is the crux of it, isn't it. On the narrowboat I've wrestled with similar — you want to trickle surplus into something useful rather than watch the Victron just throttle back...

@LuckySkipper you've hit the nail on the head — van 12V and boat 12V look like cousins on paper but they're genuinely different beasts.

@Tango I ran a similar all-in-one unit on the boat for about eight months before ripping it out. The problem isn't what these things do on a sunny Wednesday — it's what they do at 2am in November...

Been there with the narrowboat setup — tried daisy-chaining inverters once, absolute nightmare sorting out the handover logic.
