Had this exact saga with my motorhome pack last January — three consecutive mornings where the JK just vanished from Bluetooth entirely.

Running a Victron SmartSolar 100/30 in the van, paired via Bluetooth to my Samsung A54 using the VictorConnect app.

@SophieClark the bit everyone forgets is that in non-isolated mode the Orion is essentially just a fancy DC voltage converter with a shared negative — so if your Transit already uses chassis earth...

Great thread @WattTony. Honestly, for lithium I'd say the DC-DC charger alone is doing the heavy lifting properly — it's managing the charge profile correctly and protecting your alternator from...

MuddySkipper | Posts: 43 @BordersSolar interesting setup — I've been looking at something similar for a garden office install (land-based, I know, but the BMS behaviour questions are the...

Hey @DefenderLife — mid-30s during bulk isn't necessarily cause for alarm with LiFePO4, that's generally within acceptable operating range.

I've got a BougeRV 30L compressor fridge drawing around 3-4A average and a single 100Ah LiFePO4 (Fogstar Drift) in my Transit conversion.

So I've got two 200W panels wired in series on my shed roof (Renogy mono, bought last spring), feeding into a Victron SmartSolar 100/30.

Narrowboat life taught me that the real fun starts when you realise your "finished" system is never actually finished — three years in and I'm still adding fuses I "definitely...

@Davo49 the EV charging overnight is where it all falls apart isn't it. Even with decent panels you're basically running blind once the sun drops — you're drawing from whatever's left in the bank...

PanelRuss | 847 posts @Cerbo_Queen nice setup! One thing worth checking — have you told the SmartShunt the correct charged voltage and tail current for LiFePO4?

Hey @GrumpySpanner, worth checking your temperature compensation settings if you haven't already — after the update mine had reset the battery temperature coefficient to a daft value which was...

Been scratching my head over this one for a few weeks now. Running a MultiPlus-II 24/3000/70 on my narrowboat, paired with 280Ah of Fogstar Drift LiFePO4.

Hey @T5Build, good to hear it's holding up. One thing I'd add that hasn't been mentioned yet — with PWM on an AGM, you'll want to occasionally check your resting voltage after a full charge day.

Really good points from everyone here. One thing I'd add that hasn't come up yet — think carefully about your low-temperature charging situation.

@MoreTeaVicar the boat taught me this lesson painfully. Spent two seasons chasing adequate power before finally ripping everything out and starting properly with a Victron MPPT and a decent...

Good shout from @WhatsAFuse4 on the temp sensors. One thing nobody's mentioned yet — check whether your JK is mounted directly to metal or a cold surface, because the BMS processor itself can...

@GrumpySpanner mine did exactly that on the narrowboat — turned out v1.61 tightened up the tail current detection, so your Fogstar's hitting the absorption exit threshold faster than before...

Really interesting thread this — I spent a winter on a hire boat years ago and even that short stint showed me how brutal the canal corridor can be for solar, with all those overhanging trees and...

@BorderExplorer Something nobody's touched on yet — are all four cells in the same thermal environment, or is one on the end of the pack nearest an exterior wall?
