Great thread, this caught me out too last season! Worth checking your repeated absorption setting in VEConfigure as well — if it's disabled or set to a long interval, the charger won't re-trigger...

ForestBoater | 1,456 posts | 🌲 Floating Off-Grid @BenJohnson95 the efficiency degradation is what finally pushed me off the cheap units on my narrowboat.

Had this exact issue on my motorhome build last summer. The Multiplus was calling float after maybe 2-3 hours even though my Fogstar Drift 200Ah LiFePO4 was nowhere near full — VictronConnect was...

Really useful thread this — I've actually got a SmartShunt 500A on my motorhome leisure bank and separately a basic battery monitor on the starter battery, and I'd say keeping them separate is the...
@Robbo three days is actually impressive restraint — I spent a fortnight convinced my SmartShunt was lying before realising I'd set the charged voltage threshold wrong and it was never hitting...

Been running a similar setup in my cabin-on-wheels build and this topic keeps coming up, so thought I'd share what I've found. I've got an Orion-TR Smart 12/12-18A isolated wiring the leisure bank...
Had something similar crop up on my static caravan setup last winter — worth raising here because I don't see it discussed enough. Running two 12V LiFePO4s in series for a 24V bank (Fogstar Drift...
Cleggy83 | 📍 Yorkshire | ⚡ 400W panel / 200Ah LiFePO4 @MoorKev Ha, "dignity" is doing a lot of work in that sentence mate 😄 I'd push back slightly though — there IS a valid use case for...

Got a head-scratcher with my Victron setup that's been keeping me up at night (which is ironic given I'm supposedly off-grid and meant to be living the simple life). Running 600Ah of Fogstar Drift...

@PennineNomad makes solid points about the MPPT tracking. One thing I'd add from bitter experience with my static caravan setup — check your cable run length and gauge before anything else.
Been having a similar issue on my narrowboat over the past few weeks. Running a 200Ah Victron Smart Lithium and the BMS keeps tripping somewhere between 2am and 5am — always overnight, never...

@Nige1977 worth checking the VRM logs if you've got a GX device connected — you can pull the temperature data retrospectively and see exactly when throttling kicked in.

@OldSailor the Subcold Ultra 35L pulls around 60-80W when the compressor kicks in, but average consumption is typically 15-20Wh per hour once it's down to temperature — so roughly 360-480Wh over...

@BigAl makes a good point on Voc — worth adding that on a cold winter morning those voltages can spike higher than the panel spec suggests, so leave yourself headroom. On the 100/30 specifically:...
Almost certainly the carb. Old fuel goes stale and leaves a varnish residue that gums up the jets — classic winter storage problem. Few things to try before pulling the carb apart: Drain the old...
Mine did the same last winter parked in a layby near Keswick — Victron's algorithm basically has an existential crisis when the panels can't decide if they're generating 40W or 4W every thirty...
Been having a similar headache with my setup on the narrowboat. Running a Victron Orion-Tr Smart 12/12-30 feeding a 200Ah Fogstar Drift lithium and it took me ages to figure out why it kept...
@RobBennett93 Worth checking the VE.Direct port first before writing it off completely — a corrupted firmware flash can sometimes render the unit apparently dead whilst the hardware itself is...
@OffGridGeek and @Wez1961 have covered the Voc issue well, so I'll add something nobody's mentioned yet. Two failures in quick succession strongly suggests a wiring fault introducing voltage...

Yeah, standing charges are the real killer aren't they. Still paying something like 61p a day just to be connected, even when I'm barely pulling anything from the grid.
