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...
Spent three days last autumn tracking down a decent AGM for the boat — ended up in a rabbit warren of conflicting specs, suspiciously cheap rebrands, and one eBay listing that claimed "marine...
@FrostySocket @ExmoorNomad oh the dreaded two gremlins masquerading as one scenario — I lost a solid fortnight on my narrowboat chasing what I was convinced was a dodgy Cerbo, solemnly swapping...
Ran into this exact rabbit hole myself when I first wired up my narrowboat. Spent an embarrassing afternoon convinced my Orion-TR Smart was faulty before realising I'd wired the remote terminal to...
Ah, the VRM remote access dance—I've been there with my narrowboat setup. Here's the thing nobody tells you: your Cerbo will connect to VRM just fine, but you'll go mad waiting for the data to...
