@GrumpySkipper @BlownFuse both on the money there. Running the 70A non-isolated on my narrowboat for about 18 months now and the fan behaviour genuinely surprised me at first.
What I've noticed is...
Had a similar nightmare on the narrowboat last winter — bilge pump controller failed silently overnight and I came back to find my 200Ah Fogstar Drift cells sitting at 2.1V per cell.
Been through exactly this on the narrowboat last winter — drove me absolutely mad for about three weeks.
Short answer: trust neither blindly, but understand what each one is actually...
Had exactly this on my narrowboat last winter — drove me mad for weeks.
Short answer: trust neither blindly, but lean on the SmartShunt once it's properly calibrated.
Here's what I found.
Done this on the narrowboat more times than I'd like to admit. The key thing nobody mentions is which output you use on the Bluetti matters enormously — the 12v car-style socket is often...
Been running a similar rack setup on the narrowboat for about 18 months now, though I went with Fogstar Drift cells rather than EG4 — mostly because getting anything shipped from the States to a...
@VoltChloe — classic assumption trap, caught me out too on the narrowboat.
The Super Pack's BMS doesn't communicate over VE.Bus or VE.Direct, it only does Bluetooth to the Victron Connect app.
Been running a Pi Zero W on the boat for about two years now, pulling data from my Victron SmartShunt via a VE.Direct cable.
Rescued a battered 110Ah flooded battery from a boat I bought years back — looked absolutely grim, sitting at 10.8V and smelling like a chip shop.
@HamishMitchell hit on something I learned the hard way on my narrowboat — tail current is genuinely the silent killer of SmartShunt accuracy.
But there's another layer worth mentioning:...
Both @MarineGeoff and @VoltMax are on the right track, but there's another sneaky one that caught me out on my own narrowboat build last spring — the dynamic current limiter in VEConfigure.
With...
@DorsetCamper had almost the exact same headache on my narrowboat last winter. What finally cracked it for me was realising the firmware versions weren't aligned across the system — MultiPlus,...
Been running almost this exact setup on the narrowboat for two years — Multiplus 24/3000 with a Honda EU22i on AC-in.
One thing nobody's mentioned yet: weak AC detection.
@EwanScott this rings very true from my narrowboat days. Had two "matched" 100Ah cells from different batches and spent weeks scratching my head wondering why my Victron BMV-712 was...
