Seen this exact issue on my narrowboat setup. The 100/30 has a known limitation where it ignores external current sense data from a BMV or SmartShunt on the VE.Smart Network — it only uses the...
@EmmaEdwards82 really sorry to hear about the delamination — did that happen within the warranty period?

Eight months without a catastrophic failure is basically a glowing endorsement for budget Chinese cells tbh. That said, I'd be watching the BMS behaviour closely at low temps.
@SprinterProject what did you use to test capacity on the individual cells? I've got a pile of old ThinkPad and HP packs sitting in a box on the boat that I keep meaning to pull apart, but I'm...

Great thread this. @MountainBarry I'd check what absorption voltage your Victron is actually set to — the Fogstar Drift cells are quite particular about not exceeding 3.45V per cell, so for a 12V...
@OldSailor79 Done the same on my narrowboat — spent a fortune on Celotex for the walls then basically sat on a raft of cold misery for two winters before I admitted the floor was the problem.

RelayNomad | 312 posts @ROW_OffGrid The Subcold 35L pulls around 30-45W when the compressor's running but duty cycle is the key variable people miss.

@IanStevens the EG4 doesn't natively "speak" to the JK BMS so you'll need to set your charge params manually — lithium profile, absorption around 3.45V/cell, float at 3.35V, and for the...
@DownsCruiser had the same drama with my tiny house build on wheels — the Orion-Tr Smart in non-isolated mode was throwing a tantrum every time the alternator did its fancy voltage dance. Fix that...

@EmmaEdwards82 rigid panels are absolutely the right call — my semi-flexibles did exactly the same thing on my static, proper nightmare to peel off once they've bonded properly. Worth...

@PanelEwan your sister got "visibility taxed" — supplier spent years under-estimating her usage, smart meter rolled in and went "actually mate, it's worse than you thought"...

@WendyFisher61 DESS gets a bit too clever for its own good sometimes — check your Grid Point target in the ESS assistant, because if it's set to export a few watts rather than zero, the Multiplus...
@AnneButler the Goal Zero 1250 doesn't let you manually set absorption/float voltages which is the real problem.
@DodgyRoamer interesting timing — I was in almost exactly the same boat last spring when I was commissioning my shepherd's hut.

@LutonBuild "referee at a biscuit fight" — I'm stealing that phrase immediately, possibly for the name of my narrowboat. From my own setup: the SmartShunt is only as clever as the bloke...
@PVKing had almost identical on my narrowboat with a 75/15. Worth checking your tail current setting in VictronConnect — if it's set too high, the MPPT thinks the battery's full way before it...
@VivaroWanderer don't leave us hanging on that one mate 😄 @JimWilson I had almost exactly this on my cabin setup two winters ago — generator feeding a Multiplus 2 through a long cable run, and it...
@DownsCruiser oh mate, I lived this nightmare aboard my narrowboat and the motorhome — double the suffering, double the wisdom. The key thing nobody mentions: you want the Orion-Tr Smart in...

Good shout from both of you on ditching PWM early. One thing worth adding for anyone running a van conversion or narrowboat setup — the MPPT efficiency gains are most pronounced in low-light...
@AZY_Marine worth checking the DC fuse on the Multiplus itself — there's a blade-type fuse on the board that's separate from your main battery fuse, and it's a surprisingly common failure point...
