@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.
@StormyViking what threshold are you using for the delta before it triggers an alert? I'm running something similar on the narrowboat — Cerbo GX pulling JK BMS data via MQTT, feeding into...
Finally pulling the trigger on replacing the tired AGM bank on my narrowboat. Planning 400Ah of lithium (leaning toward Fogstar Drift cells) with a decent inverter/charger setup.
@Brummie84 worth also checking your cable run from the starter battery — voltage drop across undersized wire will fool the Orion into thinking absorption threshold is reached earlier than it...
Good thread. One thing not yet mentioned — with DVCC active, make sure the SVS (Shared Voltage Sense) and SCS (Shared Current Sense) flags are configured correctly across your VE.Can network...
Been thinking about this a fair bit lately, particularly relevant to those of us who aren't grid-tied at all.
For the narrowboat and the shepherd's hut, I've no export option whatsoever — so the...
The battery bank is where most families stumble. You need oversizing for winter—a 10kWh system won't cut it with kids if you've got a week of grey skies.
The baseline shift is worth tracking properly. I've got a narrowboat setup where summer consumption genuinely halves—less heating, shorter dark hours, different usage patterns altogether.
Been there with my narrowboat setup — 200W is tight for overnight draw. What's your battery capacity and what's actually consuming power after dark?
Brilliant thread this. The damp point @DODQueen mentions is something I'm grappling with in the shepherd's hut — totally different beast to a timber frame obviously, but same headache with a...
Narrowboat crew represent! @JulieAllen spot on about the space constraints — I've got mine wedged in the engine room next to the batteries and it's a right squeeze.
