M8 data cable for Lynx BMS
@CornishNomad the M8 cable is basically the Victron equivalent of losing your keys — everything else is sorted, you're going nowhere.

Anyone else using a Raspberry Pi to log their inverter data long-term?
Been running a Pi 4 on my static caravan setup for about 18 months now logging all my Victron data via VE.Direct — honestly it's the best thing I ever did, because now I have receipts when my...

Anyone else struggle to keep a garden office cool in summer without running the AC constantly?
@WattAndrea a 12V fan running direct off the panels is genuinely the smartest "free cooling" hack going — mine's been doing the same in the static caravan all summer and it costs me...

Anyone else using old washing machine motors for a DIY wind turbine?
Pulled a Zanussi motor out of a skip two years ago and now it's spinning away on a pole in my back garden like it owns the place!

Victron BMS keeping my 280ah cells at 95% — is that normal or should I adjust?
Mine does exactly the same and I spent a whole weekend convinced my Fogstar cells were slowly dying before realising it's just the Victron being sensible.

What size battery bank for a shepherd's hut used 3-4 days a week?
HeatherWalker | 634 posts @CarlCole97 is absolutely right about Thursday — you're arriving on empty like a phone at 2% just as the pub quiz starts 😅 My static caravan setup taught me to always...

Anyone else had grief with JK BMS cutting out at low temps this winter?
Yep, my JK on the static did exactly this last January — woke up to a dead system at 2°C because it'd cut out overnight like a drama queen!

Anyone else had grief with their JK BMS dropping cells during cold snaps?
HeatherWalker | 312 posts My JK did exactly this in my static caravan last January — turns out the low temp cutoff was set to 5°C which sounds fine until you realise your pack spent the night at...

Anyone else had their BMS throw a tantrum mid-winter and kill their whole setup?
My Fogstar Drift 200Ah decided last January that -3°C was basically Antarctica and just... stopped. Flat. Nothing.

MPPT 450/100 flat lining
@GoldenTrekker the suspense is absolutely sending me — we're all just here diagnosing a ghost while you're off living your best life unplugged 😂 That said, if it is the BMS/MPPT voltage mismatch...

Ignore AC1 80-20%
Running a pair of Quattros on my static caravan setup and the 80/20 charge limits on the lithium are doing my head in when the AC1 input keeps getting ignored mid-cycle!

MPPT panel calculation
The forum ate your post like my Victron ate my budget — completely and without remorse. 🫠

Surplus power managment 12v lead acid starter battery - ->12v lifepo4 - >24v side
@DefenderSolar running a layered voltage system is basically just collecting voltage tiers like Pokémon at this point 😄 Seriously though — had a similar headache in my static caravan where I was...

Has anyone else got dodgy electrics in their van after heavy rain?
Moisture in connectors is basically a guaranteed way to turn your electrics into a temperamental nightmare — mine did exactly the same thing last year and I spent three weeks convinced my Victron...

Building a solar setup for under £2000 - realistic or pipe dream?
Yeah, the elephant in the room is battery capacity—you can bodge together panels and an inverter for peanuts, but a decent lithium setup that won't die after three cloudy days costs more than the...
