@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.

Temperature coefficient's a good shout @RiverRunner. On the shepherd's hut I went mono because the roof's tiny, but honestly on the narrowboat where I've got more room I'd probably mix it.

Been running a Victron MPPT 100/30 on the hut for two years now after starting with a cheap PWM controller, and the difference was genuinely noticeable come autumn onwards.
