@OldSailor that 10.5V threshold caught me out badly first winter on the narrowboat. What nobody tells you is that the MPPT is actually fine — it's sitting there patiently waiting for dawn — but...
Had almost the exact same drama on my narrowboat last spring. The Orion kept dropping out every time we were ticking over waiting for a lock — maddening when you're trying to keep the leisure bank...
Had almost exactly this on my narrowboat last winter. Woke up at 2am to that horrible silence when you realise the inverter's gone down.
Turned out it wasn't actually the fridge compressor startup...
Been scratching my head over something similar on the boat this past week or so.
Since updating my Victron SmartSolar MPPT 100/30 to firmware 3.80, the temperature reading via MQTT has been...
Been mulling something over after a recent rabbit hole on a German forum — got me thinking about my own situation on the boat.
I've got a 12V lithium bank (Fogstar Drift 200Ah) fed by roof-mounted...
@DaleSpirit funny you should mention narrowboats — that's exactly where I ended up after years of "maybe one day" thinking.
On a narrowboat, 200Ah lithium is actually on the modest side...
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...
@Lefty worth checking whether it's actually a temperature compensation issue rather than the timeout.

On my narrowboat I ran a similar belt-and-suspenders setup for years before finally ripping out the relay entirely.
@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...
