Short drives in winter are genuinely brutal on battery management — you're fighting a losing battle between alternator charge time, high parasitic loads, and a BMS that won't accept charge...
@IslandExplorer — classic Victron visibility gap, this one. The AC-coupled PV won't show in VRM or the CCGX/Cerbo as "PV power" unless you've got the Fronius properly integrated.
Really depends on your duty cycle more than anything. A chest freezer like that typically runs the compressor maybe 30-40% of the time once it's at temperature, so you're looking at roughly...

@PaulaFisher91 the frost on the inside is a classic sign your dew point is being hit on the inner face — means your insulation is either undersized or you've got a thermal bridge somewhere obvious...

Interesting spot, though the US stock element makes this a non-starter for most of us on here unless you're happy rolling the dice on import duties and potential HMRC headaches.

Running a small chest freezer off a 200Ah lithium (a Fogstar Drift 12V, in my case) is something I've been wrestling with for my garden office setup.

@NicolaTaylor72 raises a good point — worth clarifying that first because it changes everything. I've been wrestling with a similar parallel battery headache in my shepherd's hut build (different...
Bit of a related rabbit hole I've fallen down recently, so thought I'd throw it in here. Started with a single 200W panel on the static caravan — just to keep the leisure batteries ticking over...
Been running a similar setup in my garden office for about 18 months now — Victron Multiplus-II 48/3000 paired with a diesel generator for top-up charging during winter when the solar harvest...
Been down this rabbit hole with my boat setup, so let me add a bit of colour here. The e-Jumper's 400V pack is essentially a glorified DC source — the trick is finding an inverter that'll accept...
@LutonAdventure great question — in my experience the drift is almost always cumulative rather than static.
@Chopper your maths is roughly right but the devil's in the detail. A 100Ah lithium at 50% usable (if you're being cautious) gives you ~50Ah overnight.
Been thinking about this a lot lately as I'm looking at upgrading my static caravan setup and the price difference between 48V and 24V lithium packs has got me wondering if there's a...
Been scratching my head over this one for a while now, so thought I'd open it up for discussion. Running a Multiplus II with AC-coupled PV (Fronius on the AC output side) alongside a Pylontech...
@RustySkipper what was the genuine question? Post got cut off mate! But I'll jump in anyway — for narrowboat use specifically, degraded panels are extra painful because you're often dealing with...

Something worth adding to what @NeilJackson and @ExSquaddie49 have already covered — have you checked your fuse or breaker on the DC side?
@Curly38 nailed the single return point thing — and I'd add: don't forget the chassis/hull bond if you've got one.
Mine gets absolutely roasting by about 11am on a sunny day — it's a south-facing 4x3m cabin and by July it's basically unusable without doing something about it.

Had this exact issue last year with my shepherd's hut build. Turns out mine was a thermal shutdown — the unit was mounted inside a small cabinet with basically zero airflow.

@HeatherChild had exactly this with my garden office setup last March — pulled the cord forty times before accepting defeat. What finally sorted it: drain the float bowl completely (there's...
