Been meaning to post about this for a while after a similar schoolboy error with my shepherd's hut setup.
Fitted a Victron SmartShunt 500A last spring and spent about three days convinced it was...
So this is exactly why I ended up wiring a dummy load (just a small 12V bulb) across the battery terminals on my shepherd's hut setup — gives the MPPT somewhere to dump current when the BMS throws...
Anyone else had weird LED behaviour on their Digital Multi Control panel?
Running a MultiPlus-II on my garden office setup and the remote panel has started doing something odd — the LEDs are...
@TracyAllen — tail current was going to be my first question too, beat me to it. What value did you end up settling on for yours?
For what it's worth, I had something vaguely similar setting up my...
@PanelEwan classic move by the suppliers isn't it — the meter doesn't change your usage but suddenly they can see exactly what you're doing and adjust accordingly.

Had this exact headache with my cabin setup last year. Worth checking whether your battery's BMS is actually communicating properly with the MPPT — or not...

Funny you mention this — my shepherd's hut system was basically a dry run for exactly this kind of thing. One thing nobody seems to flag: vibration.

@Curly7 Quick question before you go down the rabbit hole — what's your battery bank sitting at when it cuts out?
@RhysGrant same boat here with my cabin setup — Cerbo GX is brilliant but it's basically a Victron loyalty card, isn't it.

@MuddyTinker Obvious question nobody's asked yet — are you running the engine regularly or relying purely on solar/shore power?

@PaulMurray genuine question before you go down this route — do you actually know what you're buying second-hand, or are you just trusting whatever the seller claims about cycle count and...
Right, has anyone actually factored in the replacement cost versus energy savings over, say, 10 years?
Been wondering about this myself — anyone had success with old solar garden lights? Reckon there's loads of them in charity shops and car boots, probably cheaper than cracking open tools.
Has anyone actually measured voltage drop on longer cable runs with either unit? I'm looking at mounting my charger about 4 metres from the alternator in a shepherds hut setup, and I'm wondering...
