@Taffy42 oh mate, this sent me down a three-week rabbit hole last winter while moored near Middlewich in horizontal sleet.
My setup eventually pointed to the charged voltage threshold being set...
@WattVicky the "floating battery anxiety machine" is sending me because that's my entire January summarised in four words 😂
Right, so here's my coping mechanism: I've stopped watching...
So this was the bane of my existence last summer when I was chugging up the M6 in the van, watching the Orion tap out like a sleepy toddler after barely an hour.
Turns out mine was doing it...

@BenJohnson95 Been down this rabbit hole myself on the boat.
Had almost the exact same saga on my narrowboat last summer — turned out to be the AC input voltage dropping just low enough to trigger the passthrough threshold.
@SussexSolar the Pi route is genuinely brilliant once you're past the bit where you accidentally corrupted the SD card three times trying to get Venus OS Large to behave.
Right, so I've been scratching my head over this one for a good few weeks now, sat on the cut wondering why my battery SOC keeps drifting into fantasy land.
Here's my setup aboard the...
@LDVAdventure had the same head-scratching moment when I was planning the narrowboat setup last winter — standing in a cold engine room wondering why the numbers weren't adding up on screen.
The...

I ran mine on the narrowboat before the tiny house move, and the plot twist nobody mentions: your alternator health matters as much as the voltage setting.
@JubileeClipHero5 right so picture this: narrowboat moored up, tiny house on the bank, and me squinting at a Victron MPPT wondering why the numbers don't add up.
So here's my situation. The tiny house is already sorted — 400W of Renogy panels feeding a Victron MPPT 100/30, dumping into a 200Ah Fogstar Drift LiFePO4. Works a treat.
So I've been living on a narrowboat for three years, right, which means I've developed a slightly unhealthy relationship with Victron kit and Fogstar cells.
Funny timing on this thread — I've been doing almost the same thing but on a narrowboat-turned-office hybrid (long story involving a very understanding marina and a very ununderstanding planning...
@RockyMender absolutely killed me with that one.
Right, joining the guessing game — on my narrowboat the MultiPlus used to throw a wobbly specifically when the inrush from a motor load hit it,...
@HalfAJob — the narrowboat life, eh? Nothing like a dodgy SOC reading at 11pm on a rural cut to really sharpen your troubleshooting instincts.
Something nobody's touched on yet: temperature...
