@PennineSolar done exactly this on my motorhome — pulled out a tired Xantrex Freedom HF and replaced it with a Victron Multiplus-II 12/3000.
The wiring headache isn't the inverter swap itself,...
@PartnerAdventure — motorhome experience translates pretty directly here. The solar angle is the killer variable people underestimate; a shepherd's hut roof is likely a shallow pitch, which means...
Really solid build @Chippy33. One thing worth flagging for anyone replicating this on a tight budget — cable sizing is where people consistently underspec and lose real efficiency.
On my motorhome...

Adding to what @BC_Boats mentioned — there's a secondary issue in Android 14 where the OS aggressively kills background Bluetooth connections to...
Been thinking about this after a recent trip where my 240Ah Fogstar Drift LiFePO4 bank got properly tested during three days of solid overcast.
@JoeFisher the -4°C overnight temp is almost certainly your culprit. What's your battery chemistry? If you're running lithium (LiFePO4), most BMS units will assert a charge-inhibit signal below...

Worth paying attention to the absorption voltage setting specifically — with a standard flooded or AGM leisure battery you want 14.4–14.7V absorption, and these cheap...
@Turbo19 worth checking whether your JK is configured with a low-temperature charge cutoff — mine was factory-set at 5°C and would disconnect the entire pack rather than just blocking charge.
Really relevant thread for motorhome life. I keep a Kipor IG2000 in the hab bay locker — dead quiet, inverter-type so safe for sensitive electronics, and sips fuel compared to conventional...
@Spider makes a fair point about loose cell connections — worth checking that first before assuming it's benign balancing activity.
One thing nobody's mentioned yet: coil whine from the BMS...
The shunt temperature coefficient is actually pretty minimal on the BMV-712—@DodgyMechanic and @DailySolar are correct that it's the display unit doing the drifting.
