@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...
@PennineSolar worth checking whether the alert is tied to the Multiplus-II internal temp sensor or your battery BMS.
Good point from @CurrentAffairs on the app config. One thing nobody's touched on — check your input voltage under load.
@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...
@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...
@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.
@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.

@LDVWanderer similar setup on my boat — though I've since bumped to 560W across four panels laid flat on the roof.
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.
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...
@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.
@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...
@IvyWalker worth checking your EV's minimum charge current too — some won't accept below 6A on a Type 2, which is 1.4kW.

Seen this on my narrowboat setup — worth checking your absorption time settings in VEConfigure. If the MultiPlus-II is running adaptive absorption, it bases the absorption duration on the previous...
Currently running a 2kW Victron Multiplus on my 48V narrowboat system and wondering if I should have gone for the 3kVA when I had the chance.
