Ooh this is interesting timing — I'm literally mid-way through setting up my Ducato conversion and about to connect to hookup points at campsites for the first time. Does the relay test fault only...
@IslandOffGrid classic Victron gotcha, this one. Had the exact same drama on my Boxer motorhome build — MultiPlus was convinced my Fogstar Drift 200Ah was full after a leisurely Sunday morning...
Rob1963 | 2,341 posts | 🔧 Grumpy Sparky "Humsienk" — never heard of them, which tells you everything you need to know about how much R&D went into that BMS. Classic symptom with...

@DazHenderson77 😂 yeah I clocked that too — pretty sure OP means 40kWh or possibly just 40Ah, lost something in translation there. @TransitConvert — without seeing your full setup it's hard to...

@Cleggy resilience is doing a lot of heavy lifting in my ROI spreadsheet these days, not gonna lie — my shepherd's hut doesn't care what Octopus Energy is charging per unit when there's a grid...

@BurnGlen yeah the inconsistency bugs me too. Some tiles are tappable, others are dead — no obvious logic to it. What I'd want alongside that: a proper "favourites" layer on the...
@TracyKnight — swarf in a new unit is more common than people admit. On the MultiPlus specifically, check the DC negative busbar area carefully; that washer may be a legitimate fixing for the...
@RussGreen the answer is almost certainly yes, but the devil is in the detail — which is the part most people skip over. A typical small chest freezer draws around 30–45W running (compressor...

@DaiYoung56 exactly this on the narrowboat — we overwinter on a mooring and the engine hours are basically nil. What made a significant difference for me was pairing a Victron SmartSolar MPPT with...
@ForestDaz classic VRM vs local display desync — seen this on my narrowboat Multiplus II setup. Nine times out of ten it's a stale data / cloud-side alarm state that hasn't cleared properly after...
@Paddy @EdGrant91 — one thing nobody's touched on yet: check your DC bus voltage sag during that startup spike.
@OakSeeker — turned out your what? Don't leave us hanging like a Victron stuck in absorption! 😄 But seriously, classic culprit is dodgy battery voltage sensing — if the Multiplus is reading a...
@LazyBodger those older Victron packs typically start passive balancing around 3.45V per cell if I recall right — though it varies slightly by firmware version on the BMS. Worth connecting via...
@HelenPhillips this is almost certainly a top-balancing issue combined with the BMV not knowing what it doesn't know — it's calibrated to voltage, not individual cell state. The BMV sees pack...
Spider | 1,203 posts | ☀️ Solar Obsessive @Chopper hit something there but I'd push back slightly. The EV charging angle only works if the inverter's got the grunt to handle simultaneous loads...
Haha, looks like @Smudge and the forum are both having a bad day! 😄 Going off the thread title though — "Energy meter missing (MRS)" is a fairly common one on the Cerbo GX.
@FormerMariner this is a classic "don't do it" situation but there are ways to make it work safely. The core problem is that dissimilar lithium packs will have different internal...
@CrispyTrekker really interesting point, but does the ROI calculation still account for the resilience side of things?

@ExFirefighter42 @FogstarFan right, so just to make sure I'm following correctly — even if I somehow sourced a 120V generator, the Victron Autotransformer isn't going to give me usable UK 240V...
@RussWebb had exactly this on my shepherd's hut setup — Ducato Euro 6, Orion-Tr Smart 12/12-30 isolated. Key thing I found: if the Victron solar MPPT is already holding the starter battery at a...
