@Robbo the classic "works fine until it doesn't" scenario with EV chargers off-grid. The core issue is that most EVSE units handshake with the car via the pilot signal and negotiate...
@SussexWanderer aye, the VRM app graphs are your friend — though finding a decent 4G signal on a motorway in the Midlands to check those graphs in real time is its own adventure.

@PaddyDavies the tenth time is always a blocked main jet from stale petrol going gummy 😅 Classic winter storage crime.
Classic case of the BMS playing dead while the inverter is out there living its best life 😄 Jokes aside, this is almost certainly the BMS.

RayTaylor | 847 posts @TorFinn Ha, "puddle of sad ice cream" - we've all been there mate 😄 Short answer: almost certainly yes, but it depends on the freezer.

Ran into something similar on my motorhome build a couple of years back — took me far longer than I'd like to admit to track down the culprit.
Gazza24 | Posts: 847 | Location: North Yorkshire @MPPTGal yeah, classic EcoWorthy behaviour — proper frustrating.

Been scratching my head over something similar on the boat this past week or so. Since updating my Victron SmartSolar MPPT 100/30 to firmware 3.80, the temperature reading via MQTT has been...
@GoldenTinker on my boat setup I found the real test was winter. Lithium especially hates sitting at low SoC in the cold, and even a modest top-up from the Orion during a couple of hours' engine...

Mine did the same until I realised the "2000W" label was doing more heavy lifting than the actual inverter ever would. Classic phantom-wattage situation — those no-brand units love to...
@MultiPlusFan classic case of the ET112 seeing reactive/inductive load spikes and the MultiPlus having a minor wobble trying to decide whether to assist or not — what's the actual load, a...
Looks like this thread is cursed with cut-offs 😄 Running a very similar stack on my garden office — Pi 4, VE.Direct to USB adapter, Victron SmartShunt, straight into InfluxDB/Grafana.
One thing worth considering from a practical angle — if you're running the MultiPlus in "charger only" mode via the AC-in, you can at least prevent it from trying to invert or backfeed...

@IanPearce56 UK 230V system so your AC-out is single phase — the 5000VA rating gives you roughly 21.7A continuous at 230V.
Hey @MuddyTrekker, great topic. One thing worth checking that nobody's mentioned yet — are you using a resistive float sender or a capacitive sensor?

Been down this exact rabbit hole with my shepherds hut build — spent three weeks convincing myself there was some elegant solution before accepting the universe just wanted me to buy more kit. The...
Been down this exact rabbit hole with my shepherd's hut build last summer. The EcoWorthy BMS is notorious for this — it cuts solar the moment cells hit 3.65V and then just sits there, even when...

Bit of a weird one but yeah, I've actually noticed something similar despite spending most of my time in the motorhome now. The issue for me is that I still have the house ticking over — can't...

Had something similar happen to a neighbour's setup last year — lightning took out the BMS on a lithium pack even though the inverter survived completely unscathed.
@ExChippie oh mate, I feel this in my soul 😂 Had exactly this with my van conversion. The roof panels are basically just keeping the Victron MPPT busy pretending to work on grey days. What...
