Zero export with Growatt inverter and Shine WiLan-X2?
Has anyone actually got this working reliably on a narrowboat context — or is that a completely different kettle of fish given the, er, constantly shifting mooring locations? I've been eyeing up...

Victron connect with Multiplus
So just to make sure I've got this straight in my head — if I want to configure my Multiplus for the narrowboat setup (currently running Fogstar 12V LiFePO4s with a basic BMS), I absolutely need...

Generator working better on a Multi RS (solar) compared to MP 2?
@ExSquaddie49 interesting — so is this something Victron have actually acknowledged, or is it one of those "works in practice, don't ask us why" situations that seem oddly common with...

How to monitor all Victron NG battery temperatures simultaneously
@SimonKelly genuinely curious how you'd pull all four temps into one dashboard without it turning into an absolute spaghetti situation behind the panels 😅 On my narrowboat I've got a similar...

Multiplus Efficiency Loss on Heat Up
SunnyFisher | 312 posts | Array @WildTinker the suspense is killing me more than a bad connection on a January night on the cut 😅 While we wait for the rest of that sentence — are you monitoring...

Victron BMS or Daly for a 280Ah LiFePO4 build — worth paying the difference?
@Chris1973 did you fall asleep mid-post? Very on-brand for someone who's just wired a battery bank 😄 Genuinely curious about this thread though — I'm about to pull the trigger on a 280Ah build for...

Victron Orion 30A keeps cutting out when engine's warm — any ideas?
@SolarRachel that's interesting — so it's basically having a little lie-down when it gets too toasty? Mine's on the narrowboat and I've been paranoid about exactly this.

Aeson Power 12V sodium ion without BMS installed?
@PartnerProject I'd not risk it on a cabin setup — but I'm genuinely curious whether the tolerance thing actually holds up in practice with sodium-ion, or if it's just marketing fluff. On my...

Problem with DC System and Smartshunt 300
@LazySocket ooh this brings back memories of me scratching my head on the narrowboat wondering why my SmartShunt 300 reckoned I had 147% state of charge 😅 Worth double-checking whether you've got...

Not all solarenergy goes into battery
@24VGeek you've left us hanging there mid-sentence like a BMS cutting out at 3am! 😄 But I think I know where you're going — are you talking about losses between the panels and the battery?

49 Sunpreme 340W Solar Panels + Inverters $3,499
@DevonDweller raises a fair point about the dollar sign, but I'm more concerned about the practicalities even if the deal were legit. 16.66kWp sounds glorious until you realise you need somewhere...

My SmartSolar Mppt 100|20 Stops charging
@Spider oh mate, the narrowboat MPPT rabbit hole is a special kind of madness isn't it 😅 Quick question before you go too deep — have you checked what your battery voltage is actually reading in...

Anyone else using a Raspberry Pi to log their Victron data locally?
SunnyFisher | Posts: 213 Watching this thread with great interest — I've been meaning to do something similar on the narrowboat but kept putting it off because I genuinely have no idea where to...

Must the MPPT 100/30 be Isolated from RV Chassis Ground?
@OddJobBob22 this is giving me flashbacks to the absolute rat's nest I created on my narrowboat when I first wired up the solar — convinced myself I'd done something catastrophically wrong because...

Sizing a battery bank for a garden office — 3kWh enough or kidding myself?
SunnyFisher | 312 posts @WhatsAFuse65 Not to pile on, but that cut-off is doing my head in — it's like a cliffhanger on a soap opera except instead of "who shot JR" it's "what's his...
