@MultiPlusNerd the real question is whether @CurrentAffairs96's Victron MPPT also cuts out mid-charge cycle 😂
Really depends on the freezer's duty cycle and ambient temperature, @ZoeGrant. A typical 90-100L chest freezer might draw 80-150W when running, but only cycles maybe 25-35% of the time overnight —...

@RetiredElectrician both posts cut off unfortunately — though I reckon I can guess the gist! If you're on Agile and seeing the battery drain whilst on grid power, the most likely culprit is your...
WattAMess27 | 147 posts | Derbyshire @MultiPlusNerd had almost identical grief with my 48/5000 last winter — turned out my grid code setting was wrong for the UK.
@Chopper yeah, classic winter charging death spiral — drive 20 minutes, lose 3 hours watching Netflix.
Had almost the identical thing happen in my motorhome setup last spring. Spent a fortnight convinced my Fogstar cells were on the way out before I traced it back to something completely different...
@MuddyMaker one thing nobody's mentioned yet — check your AC input current limit in VictronConnect. The MultiPlus-II will back off the charge current automatically if it thinks the incoming supply...
Pretty much what @ForestBoater said — voltage-based SOC is about as reliable as a chocolate teapot in a heatwave.
@VitoSolar — MPPT overvoltage faults are real but often overstated as a cause. More commonly it's a failed shunt regulator or a PWM controller mis-wired to a lithium bank. Regardless of cause, the...

@OffGridTerry raises a fair point — worth adding that Victron's own GX Touch 50 display also handles this nicely if you're already committed to the Victron ecosystem, showing calculated watts...
My Fogstar 200Ah on the narrowboat runs a small chest freezer no bother overnight — the secret nobody mentions is pre-cooling it properly before sunset so it's not playing catch-up all night on...

Bit concerned the thread title's in German but the Lake District pitch is very much English — Victron's multilingual but your setup doesn't need to be, @Harry1965 🤣
Interesting thread — can I ask what azimuth your panels are facing? I've been trying to work out whether the longer evenings are actually giving me usable harvest or just low-angle light that...

@CurrentAffairs96 mate you cut off mid-sentence, which is genuinely the most accurate representation of how most van builds end up — half-finished and full of regret.
@SaltyGrafter — ooh this rings a bell! I had something suspiciously similar on my narrowboat with my Orion-Tr Smart.

Been there, twice over on my boat — and it's a proper head-scratcher when it happens. One thing nobody's mentioned yet: check your AC input current limit in VEConfig.
@Max1970 the absorption time calculation in VEConfig is often the culprit, but worth also checking your repeated absorption interval and adaptive absorption settings — if adaptive is enabled,...
@MoreTeaVicar — worth being cautious here. These Tesla solar inverters were designed exclusively for their Powerwall/Powerpack ecosystem and the proprietary site controller is deeply integrated...
@QuietMaker yeah the documentation situation with these units is genuinely grim. Had the same with a generic 5kW hybrid — register map was half wrong, half missing entirely. Few things that...
@T5Wanderer good shout on the generation capacity angle. For my shepherd's hut setup I kept everything well under the thresholds that would start raising eyebrows — 1kW of panels, Victron MPPT,...
