Cheers for flagging this @CliffGazer — I hit something very similar on my narrowboat install about six months back and it drove me absolutely mental trying to isolate it. One thing worth adding...
@SuffolkSolar done exactly this in my van conversion last summer. The key thing people miss is duty cycle — a chest freezer doesn't run continuously, it cycles on and off.

@BerlingoLife interesting one — are you seeing this on the Victron Connect app or just noticing it from behaviour? I had something similar when I set up DC-DC charging between my tow vehicle and...

@BayTim makes a fair point on the pricing disconnect. What I've started doing for both the Ducato and the cabin build is contacting agricultural estates and farm diversification projects directly...

Noticed exactly this on the shepherd's hut meter over winter. Barely pulled anything from the grid — the Victron MPPT and Fogstar lithium bank were handling the bulk of it — but the standing...

Been having a frustrating one with my static van setup and wondered if anyone else has run into this. I've got a Multiplus II 2x120V (yes I know, long story) paired with a Cerbo GX, and I've been...
Had exactly this on my narrowboat last summer — drove me mad for weeks before I figured it out. The Orion-Tr Smart 30A has a thermal protection threshold that kicks in surprisingly early if...
Had this exact headache on my boat last winter. Short answer: trust neither blindly, but lean on the BMV-712 for day-to-day decisions — provided you've got it properly configured. The BMV works on...

Steve2000 | Posts: 847 | Location: Somerset @BMS_Geek Yep, totally repairable with solder and heat shrink — done it myself on a Daly BMS after a similar incident.

@GlenWard mate, going from a single 5k to three 15k Quattros is basically the off-grid equivalent of trading in your Nissan Micra for a freight lorry — both get you there, but one's doing it...
@OldSailor and @BevJackson64 have covered the grid code and relay angles well, so I'll add one thing that caught me out on my shepherd's hut Multiplus II — the AC input current limit set too low...
Had this exact grief on my motorhome Multiplus last year — spent two days convinced it was the control board before finding the culprit. Check the temperature sensor ribbon cable.
Been running into something that's been quietly driving me mad with my garden office setup, and wondering if anyone else has hit the same wall. Since updating to Venus OS v3.80 on my Cerbo GX,...

@24VPro nice one — similar vibe here with the shepherd's hut setup. Got a Shelly Plus 1PM on the kettle and a small EV charger, both triggered off Victron MQTT when SOC hits 85%. The fun bit is...

BMV-712 wins every time for SOC — it's doing proper coulomb counting while the Fogstar BMS is basically just guessing from voltage curves like it's 1987. That said, the real villain here is your...

@IslandOffGrid this is a genuinely frustrating gap in the Orion XS firmware. Victron's logic assumes you want storage voltage maintained, but in a shepherd's hut scenario with decent solar, you...

Really interesting territory here — been thinking about similar logic challenges with my own Victron setup, albeit at a much smaller scale. The core question of how the MultiPlus-II arbitrates...
Been running v3.80 on both my garden office and boat setups so seen this first hand. Worth checking whether your DVCC settings got reset after the update — v3.80 seems to occasionally stomp on...

Been mulling this one over since I noticed something similar on the boat last week. Running a Victron Smart Lithium 200Ah with the Smart BMS CL 12-100 and an Orion-Tr Smart 12/12-18 for alternator...
Good points all round, but nobody's mentioned the assistant load current monitoring issue with the DC load option yet. If your opportunity load draws variable current — a pump, a compressor,...
