Good shout from @Taffy55 on the GX, but if that's overkill for a straightforward dual-bank setup, worth knowing the BMV-712 actually handles two batteries natively — the main shunt monitors your...
Made this switch last year on my static setup rather than a boat, but the charger compatibility issue is identical — worth sharing.
The problem is almost certainly your charger still being set to...
Running a small chest freezer off a 200Ah lithium (Fogstar Drift 12V if it matters) and trying to work out if I've got enough capacity to get through the night without the solar doing anything...
@DodgySocket good shout on the charge profile — and worth adding that the Fogstar Drift's BMS will cut out if you push absorption too high.
Running a small chest freezer off-grid and trying to work out if my battery bank is going to cut it overnight without the solar doing anything.
I've got a single 200Ah 12V lithium (Fogstar Drift)...
Been down this rabbit hole for about 18 months now and honestly it's one of the more satisfying projects I've tackled.
I'm running a rewound induction motor from an old Hotpoint (rescued from the...
@MV_Marine the marina context is interesting — condensation and salt air will wreck your battery terminals faster than anything if you're not on top of it.
Rather than oversizing capacity, I'd...
For a shepherd's hut that size I'd lean 24V honestly. The moment you're running a kettle through an inverter, your cable runs start mattering.
@Compo27 yes, seen this exact thing with my setup. The MPPT is reading voltage-based SOC and LiFePO4 has an incredibly flat discharge curve anyway — add cold temps into the mix and the resting...

@MidlandsCamper the used panel angle is interesting though — we do have a decent second-hand solar market here if you know where to look.
@Tango the winter solar harvest in the UK is genuinely brutal — even a clear January day you're looking at maybe 3-4 peak sun hours at best, and that's optimistic.
One thing worth considering is...
Been running a similar ESS setup here and hit a frustrating issue I wanted to throw open to the group.
I've got two Multiplus-II 5kVA units running in parallel, Cerbo GX, a Carlo Gavazzi EM24 grid...
I'm with @CrafterSolar on this one — blanket dismissal isn't quite fair, but context matters enormously.
The real question is: which second-life pack? Nissan Leaf modules?
