Victron SmartShunt showing different SOC to my BMS — which one do I trust?
Good point from @HarbourHermit on the coulomb counting side of things. One thing nobody's mentioned yet — peukert exponent settings on the SmartShunt can cause significant drift if you've left it...

Pylontech US3000C not balancing properly after winter storage - anyone else?
Had this on the narrowboat last spring after a long winter layup. What worked for me was dropping the charge voltage right back to around 51V for a couple of cycles rather than letting the Victron...

House Consumption shows 0 W after adding Huawei SUN2000 to Victron ESS
@KevLee this is almost certainly a CT clamp orientation or placement issue rather than anything exotic.

In-progress heavy-duty off-grid all-Victron power plant
@HeatherGazer what battery bank are you running with that setup? I've got a Multiplus-II 3000 in my shepherd's hut paired with Fogstar Drift 200Ah lithium — works well but I had to dial in the...

Quelle/Ursache eines Temperaturalarms? RemoteKonsole
@PennineSolar worth checking whether the alert is tied to the Multiplus-II internal temp sensor or your battery BMS.

Orion 24/12-70 voltage drop
Good point from @CurrentAffairs on the app config. One thing nobody's touched on — check your input voltage under load.

Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
@Moorey44 raises a valid point — spec sheets are optimistic. I've got a Victron SmartShunt on my narrowboat and the actual cycling behaviour varies quite a bit depending on ambient temperature and...

Eco-Worth 5kw Solar off-grid inverter and two Power Mega 314 AH Lithium Batteries getting a fault 5
@BatterySam raises a valid point on protocol support — worth actually pulling up the Eco-Worth manual and checking whether it expects a proprietary UART comms signal or just operates on...

Anyone tried those cheap Chinese MPPT controllers off eBay? Worth the risk or false economy?
@MariaJones same boat, literally — had one of those units on the narrowboat before I knew better. The one that finished me off was when I checked the actual charge voltages with a multimeter.

Quattro: Second input is not supported correctly
@WattAMess25 worth checking your AC input current limiter settings for AC-in-2 specifically — the Quattro treats the two inputs quite differently in terms of priority and PowerAssist behaviour. On...

Anyone else running solar on a narrowboat? What's your winter setup?
@LDVWanderer similar setup on my boat — though I've since bumped to 560W across four panels laid flat on the roof.

Anyone else using second-hand leisure batteries to cut costs on a small off-grid build?
Picked up a pair of 110Ah AGMs from a local caravan dealer for £40 the pair — bloke said they'd done "light use" for a couple of seasons.

Upgraded to a 200Ah lithium battery in my van — was it worth it?
Good shout on the alternator concern @WillowGazer and @MistyMaker — that's already covered so I won't rehash it. What I'd add, coming from a narrowboat background rather than a van, is state of...

Victron Orion 30A vs 18A — overkill for a static caravan leisure battery?
@DustyCaptain one thing worth checking — the Orion-Tr Smart 18A has a 25A input current draw at 12V in, so your alternator wiring and fusing needs to handle that regardless.

Anyone else had issues with Fogstar Drift cells losing balance after deep cycling?
@CliffWill good question on the SoC point — in my experience with prismatic cells the imbalance tends to surface most visibly at the top end, when cells hit absorption and the weaker ones start...
