@PanelEwan totally agree it's a nightmare. I've been running my shepherd's hut fully off-grid for two years now and honestly the standing charge alone was nearly justifying the switch before I'd...
Been having a similar head-scratch with my static caravan setup recently. Running a Victron Multiplus II with a Fogstar Drift 100Ah and I thought I'd locked out grid charging entirely through the...
@Moorey44 finish your post!! 😄
Had something vaguely similar on my static last year — Victron was throwing fits but voltages looked reasonable.
Had this exact headache last summer in my shepherd's hut build. Short answer — trust neither blindly, but lean on the BMS for lithium.
The BMV-712 is brilliant but it's coulomb counting, so any...
Worth checking if the BMS has a manual reset button or a separate low-voltage recovery mode first — some cheaper packs go into protection and just won't wake up without a small external charge...
Had a Bluetti AC500 on my radar for a while but ended up going Victron/Fogstar route for the shepherd's hut instead.
Same setup in my shepherd's hut actually — Multiplus-II with a Drift 200Ah.
One thing worth adding: the Drift communicates over Victron's VE.Bus/CAN path, so GX device users (I've got a Cerbo GX)...
Good shout from @MoorRuss and @PanelEwan on the cabling side. One thing I'd add — worth checking your battery state of health if it's been sitting over winter.
@RetiredEngineer86 had a similar dilemma last year sourcing cells for my shepherd's hut build. Ended up going Fogstar Drift 48V instead — yes it cost more upfront but at least when something needs...
Worth adding — the ESS assistant in VE.Configure is where a lot of the magic actually happens for this kind of thing.
@AnneWatson beat me to the unswitched bit but worth adding — the Multi RS AC out 2 is really just meant for non-critical loads, not for feeding power back into the system via a grid-tie inverter.
@VivaroNomad had exactly this dilemma when setting up my static caravan. Ended up going Fogstar Drift after bottling it on three different eBay listings 😅
The price difference felt painful at the...
@TQ_Builds tag your post and edit it to add the rest of the details — we can't really help without knowing what the actual problem is 😅
That said, I've got a similar-ish setup in my shepherd's hut...
Done exactly this with my shepherd's hut build 😬
Spent ages spec-ing out the Multi RS Solar then nearly bought a job lot of panels without checking the Voc properly.
Had this in my shepherd's hut last February — brutal wake-up call. Ended up wrapping the battery box with some cheap closed-cell foam insulation and it made a surprising difference.
