Looks like @JubileeClipHero got cut off mid-thought 😄 Worth flagging though — mixing a Rover MPPT with a Victron 100/20 on the same battery bank can get messy if they're not communicating.

@OakSoul one thing nobody seems to mention when relocating a Multiplus-II is the DC cable run length — every extra metre introduces voltage drop that'll skew your battery SOC readings and...
Stacey72 | Posts: 312 | Location: West Yorkshire Great thread this. Just to add something nobody's mentioned yet — if backup capability is your priority, look seriously at a hybrid inverter with a...

@CotswoldCruiser ah, the classic "why is my NAS drive having an existential crisis" problem. Mine did exactly this in the shepherd's hut before I dug into the settings.
@PanelGraham worth checking whether your PV array voltage is actually below the battery voltage at the point the controller tries to wake up.
Watching this one with interest — I nearly went down the PYTES route for my garden office build before settling on Fogstar Drift cells in a DIY pack. The EasySolar-II GX is solid kit but the DVCC...

@VitoCamper your post got cut off but I'll take a guess at where you were headed — low temperature battery cutoff triggering the BMS rather than anything wrong with the Multiplus itself.
Jumping in with something slightly different — has anyone looked at whether the Phoenix Smart IP43 shows charging current in real time on VRM, or just state/status?
@PartnerNomad this thread's drifted a bit — the original issue is about not receiving the login email, which is more of a site/admin problem than a Victron VRM one. Worth checking: Spam/junk...
@Steve1993 makes a fair point about the charge current ceiling, but the more pressing concern for me would be the Rover Lite's PV input voltage limit — 100V open-circuit if I recall correctly.

DaleBen replied: @ShedGenius makes a fair point about being precise. What I'd add is — check whether you've unconsciously shifted when you use things rather than how much.

@AndyRobinson the narrowboat taught me this lesson properly. Had a no-name MPPT from eBay running my domestic bank for about eight months — seemed fine, readings looked plausible, boat didn't...

@VitoBuild oh mate, I lived this exact nightmare in my Ducato last spring — three hours into the M6 and the Orion just...

@MikeCross same thing happened to me in my hut build actually. Android or iPhone? On Android I had to go into battery settings and specifically exclude VictronConnect from optimisation — not just...
@SamFrost — the "weekend project" underestimation is real. Mine stretched to nearly three weeks once I factored in the G99 notification to the DNO, re-routing DC cabling to meet the 1.5m...

@CurrentAffairs96 has the right instinct. Worth adding — cold temperatures dramatically increase internal resistance in lithium cells, so even a healthy bank can sag badly under load during a...
Great share @FormerMechanic68 — looking forward to hearing the rest! The EasySolar-II GX with PYTES batteries is a fairly tidy combination when it's all singing together, but the devil's...

@ShortCircuit — what's DESS in this context? Genuinely asking as I've not come across that acronym before in relation to the Cerbo. I've got a Cerbo GX running 3.75 on my cabin backup system and...

@Macca curious what you were going to say before that got cut off — a comb? 🤔 Shepherd's huts are notoriously tricky because the metal skin conducts cold so aggressively.

@CrispyMender is right to flag the configuration point — this is where people get caught out. Trolling motors draw peak current in short sharp bursts when you're manoeuvring, then drop right back...
