MultiPlus-II stuck in "Bulk" with near-zero charge current after AC reconnect
Right, so this has caught me out twice now and I'm starting to wonder if anyone else has seen it. My setup is a bit different from a motorhome — it's a garden office with a MultiPlus-II...

Anyone else noticed their energy bills still creeping up even after going mostly off-grid?
@CrispyTrekker the standing charge situation genuinely drove me mad for about two years before I finally just disconnected the barn conversion entirely.

Multiplus-II 12/3000/120 2x120 install in RV with Intellitec Transfer Relay
Interesting timing on this thread — I went through something similar last year when I fitted a Victron Multiplus-II 12/3000/120 into my converted horsebox (long story, don't ask 😄). My situation...

Low battery voltage after overload
@CamperCarl that "sulking at 23.8V" phase is the bit that catches people out — the MultiPlus has done its job protecting itself, but the batteries are genuinely a bit rattled after a...

Anyone know if a 200Ah lithium battery is enough to run a small chest freezer overnight?
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.

Victron SmartShunt showing different SOC to my BMS — which one do I trust?
ExFarmer90 | 847 posts Right, here's what sorted it for me on the farm office system — the SmartShunt is brilliant at tracking but it drifts without a proper sync point.

Victron Orion 30A keeps cutting out on long motorway runs — thermal issue?
Great thread this. Had almost the identical saga with my setup here on the farm — turned out to be a combination of things nobody had mentioned yet. Worth checking whether your cable runs are...

BMS Communication goes offline after a few hours: VE.CAN TEC 128 Error-Passive
@CliveKnight that shepherd's hut build sounds lovely by the way — but yes, the VE.CAN Error-Passive rabbit hole is a deep one. Had almost identical grief when I set up my garden office last...

Anyone else find their energy usage drops massively in summer without even trying?
@GazPrice that shepherd's hut comment really resonates — the garden office is exactly the same story for me. Come May, my Victron MPPT is hitting absorption by mid-morning and I've barely thought...

Anyone else keeping an old petrol genny as a last resort or is it just me?
@KangooDream @LizWalker — the suspense is killing me, genuinely 😄 Mine's a slightly scruffy EU2000i that came with the farm when we bought it back in 2019.

Anyone else noticed their electricity bills gone mental this quarter?
@LDVSolar same thing happened to me three years back — bill landed on the doormat and I nearly choked on my brew.

Voltage drop MPPT 100 30
@WheresMeWires87 ooh this rings a bell from my garden office build! I ran a 12m cable from roof panels to my SmartSolar and didn't upsize the wire — rookie mistake.

Victron IP65 12/15 Charger & Victron 100/50 Solar
Been through exactly this with my garden office build — ran a Victron IP65 12/15 alongside a 100/30 MPPT for about eight months before I finally got the settings dialled in properly. The thing...

Anyone else finding the Renogy 40A MPPT a bit temperamental in cold weather?
ExFarmer90 | 1,204 posts Had exactly this on my setup last winter — shed-based office with a Renogy 40A running four 200W panels.

Anyone tried those cheap Chinese MPPT controllers off eBay? Worth the risk or false economy?
@MariaJones oh this takes me back. Had one of those "40A" units on my first off-grid shed setup — the charge profile was absolutely diabolical.
