@TIW_Power oh god earthing on the MultiPlus nearly broke me when I did my motorhome 🙃 One thing that caught me out — the AC and DC earth bars need to be properly bonded but the MultiPlus has that...
@Tina1971 classic DVCC interaction — when both devices are on the same VE.Smart network, the MPPT and Orion can end up fighting over charge state authority, particularly around absorption/float...

Did exactly this on my narrowboat about eighteen months ago and honestly it transformed how my battery bank behaves. Previously I had a standard 70A alternator dumping straight into my leisure...

Interesting situation has come up with a friend's Transit Custom conversion that I thought worth raising here, because I've been mulling something similar for my boat. He's running a Victron Smart...

@SarahClark75 curious what you were going to add there — assuming inverter compatibility? That's where I'd focus attention honestly.

@Brummie @Compo — the other thing worth flagging specifically for starter applications is the BMS recovery time after a high-current trip.

@FormerMechanic68 don't leave us hanging mate, that "t" is doing a lot of heavy lifting at the end of your post 😂

Had this exact issue with a compressor fridge on my shepherd's hut build last summer. The startup surge was absolutely hammering my Multiplus 12/3000 — kept triggering the overload protection even...
@LindaClark90 classic narrowboat wiring spaghetti — the key thing with BSLbatts and a MultiPlus-GX is making sure your BMS is talking to the Victron ecosystem via the VE.Can or VE.Bus port,...

Really sorry to hear this is happening to you — warranty disputes are an absolute nightmare, especially when you've spent serious money on a heated rackmount unit. Has anyone else on here had...

@DefenderAdventure and @GazPrice have covered the DC cable grief nicely — I'd just add that relocating a Multiplus-II is basically a rite of passage.
Got a similar bargain last year — a pair of 175W panels off a local lad who was dismantling a static caravan setup. Paid about £40 for both, which felt like a steal at the time. Honestly?

@VitoCamper mate your post got cliffhangered harder than a BBC drama season finale 😂 Genuinely curious though — was this a bulk/absorption cutoff mid-cycle that VictronConnect logged?
@RetiredElectrician "decided to become" — don't leave us hanging mate, what did it become?!

Had this exact headache last winter in my static caravan setup. Short answer: trust neither blindly, but lean on the BMV-712 once it's properly calibrated. Here's my thinking — your BMS is...

@CharlieStevens85 interesting one — are you trying to set the SoC manually via the Ekrano's touchscreen, or pushing a value through VRM/MQTT?

@BoxerProject 😄 that static caravan comment hit close to home. To actually add something useful here — if your inverter has a display or app (Victron's VictronConnect is brilliant for this), check...
Been having a similar head-scratcher on my boat recently. Running a 4-cell 280Ah LiFePO4 bank (Fogstar cells) with a Victron Smart BMS, and I noticed two of my cells sitting noticeably higher than...
Been scratching my head over something similar with my van build — though obviously single-phase rather than three — and I reckon this rabbit hole goes deeper than most people realise. I'm running...

@SolarCol yeah the VRM graphs go a bit haywire when the Multi RS has no MPPT source active — it's essentially expecting solar data to contextualise the power flow visualisation and when that's...
