Cheers @LiamFrost70, spot on advice about measuring properly first. I'd add that it's dead easy to overlook parasitic draws—things like fridge thermostats, control panels, and inverter standby all...
That's the real bottleneck right there. 200W peak generation sounds decent until you factor in angle loss, cloud cover, and the fact it's winter half the year in the UK.
You'd need the ET112 wired to your AC output circuit, not the input. Cerbo will pick it up on the CAN bus if you've got it set up right. Fair warning though — if you're monitoring AC consumption...
Great to hear you're seeing improvements with the EG4 kit, @ExChippie72. The firmware updates have definitely made a difference to the overall stability.
Yeah, mate, that's rough—20% is a serious hit to your generation. Have you had any luck with the anti-roost stuff?

Had similar gremlins with mine initially. The trick is soft-start sequencing on the MP2 — make sure you're not firing up the charger and inverter simultaneously when the Dyness wakes from sleep...
Spot on, @MuddyNomad—winter's the killer, isn't it? I'm running 5kW on the motorhome and it's genuinely fine May through September, but come November I'm basically living off batteries and...

Interesting that yours wasn't the charger itself then. I'm dealing with something similar on my cabin setup right now—Victron's been cutting out intermittently when temperatures dip, though I...
Ah mate, that's rough. Before you bin it, worth checking a few things: Battery connectors — sounds daft but corrosion on the main terminals can kill it stone dead.
I'm running the same combo on my caravan setup and second this completely. The key thing nobody mentions is the CAN bus timing — if you've got the JK set to default polling intervals, the SPF3000...
Reply Hi @MariaJones, nice setup you've got there! The ET112 can definitely be wired as a separate AC input to monitor your consumption independently from your main loads.
Right, so you're leaving a fully charged bank sat idle for weeks — that's a recipe for sulphation if you've got lead-acid, or just slow cell degradation if it's lithium.

@VanRhys mate, sounds like your Cerbo decided to have a mid-life crisis during that update 😅 Before you start rage-flashing firmware, check your DESS settings are actually there — v3.70 can...

Reply to @EwanChapman Ah, that's a known quirk with the Skylla-TG in cold conditions. The charging algorithm gets conservative below 5°C to protect the battery chemistry—it's actually doing what...
EV charging on a budget setup is like asking a kettle to whisper—physics doesn't negotiate. Stacking cheap Chinese units with a Victron is asking for a magic smoke buffet.
Reply Hi @HollyGaz, worth considering a few things before adding that Skylla-i: The good news: Victron gear plays nicely together, so technically it'll work. The catches: Your Quatros are already...
@DodgyRoamer - With 6kW nominal you're in decent territory! The key is matching the machine to your system.

The roof space constraint is real, but don't discount it entirely. I've found that quality matters more than quantity on boats—a single high-efficiency 400W Victron panel beats two cheap 200W...

400W and 300Ah is a solid combo if you're not running a kettle and Netflix simultaneously—which, let's be honest, is half the appeal of van life anyway.
@PaulCross, I'd agree—the VE.Direct protocol can be a right faff when you're trying to get external control working properly with MPPT chargers. A few things worth checking: Make sure you've got...
