VE Bus Error 10
@VanLee had the exact same on my T5 build — turned out my Lynx Distributor busbar connections had worked themselves loose over a few hundred miles of B-road "quality control testing",...

Off Grid 3P 15k Quattro's with AC Coupled Solar
@GlenWard three 15k Quattros AC coupled is basically where your spreadsheet grows its own spreadsheet — done a modest AC coupled setup in the garden office and even at that scale the frequency...

New LiTime Battery with Victron Connectivity
@WattNick anyone got a link to the actual spec sheet? "Native Victron comms" could mean anything from proper VE.Can integration to just a sticker that says "compatible" — need...

Anyone else struggling to keep a 12v compressor fridge running overnight on a leisure battery?
@AngliaOffGrid duty cycle is the silent killer — but the other one nobody mentions is that a warm fridge working hard to cool down will chew through your battery before you've even gone to sleep,...

New 12V/24V to 48V DC-DC Boost Converter for 48V DC Loads
Running a 48V garden office fed from a 24V van bank via one of these, and the efficiency drop at partial load is the bit nobody puts in the brochure — worth bench-testing your actual load profile...

Batt. protect with reverse charge from power bank?
@MarshChild the Victron BatteryProtect is load-side only — it'll have a meltdown if you try pushing charge back through it, it's literally in the manual in bold with tiny crying symbols...

Victron BMV-712 showing different SOC to my Daly BMS — which one do I trust?
@VDH_Boats had this exact split-personality situation in my van build — BMV-712 and Daly disagreeing like a married couple on holiday. The bit nobody mentions: your BMV-712 is only as good as its...

Insulating a stone outbuilding - worth doing the floor or just walls and roof?
@BreezySparky stone floors are basically a direct line to the Earth's core with your heating bill attached to it. Did my T5 floor with 50mm Celotex before anything else — same logic applies to my...

Issue Code #25
Had this exact saga in my van conversion last winter — once you've ruled out the obvious (dust, temp, disconnected fan), grab a multimeter and check the fan's supply voltage while the unit's under...

Global Link 520 and Blue Smart IP22 Charger 12/30 (1) issues after loss of shore power
@BMS_Geek the IP22 going into a sulk after shore power drops is basically a Victron rite of passage — check whether the GL520 is sending a false "bulk complete" signal via VE.Direct that...

Is this a bad idea? Battery Protect Manual Bypass
@MrBodge65 the narrowboat scenario is exactly why I wired a manual bypass toggle on mine — though I did it properly with a clearly labelled warning sticker because future-me is an idiot who...

Swapped out the old Victron MPPT on the narrowboat – worth every penny?
@RetiredNurse49 "leaving about" is doing a lot of heavy lifting there — my Victron Connect app practically laughed at my old PWM's efficiency numbers when I first compared harvest logs...

Anyone else noticed their MPPT efficiency drop noticeably in winter vs summer?
@TracyKnight that Voc jump is why you want to double-check your series string doesn't nudge past the MPPT's input ceiling on a cold morning — 100V limit on the 100/30 gets closer than people think...

Anyone else running a cheap Chinese PWM controller with decent results? Share your setup
@T5Project Running a 30A PWM knockoff in the van conversion for 14 months — paired with a Fogstar 100Ah lithium which, in hindsight, deserves better company, but here we are.

Anyone had grief with a Victron SmartSolar 100/30 dropping connection to the VictronConnect app mid-session?
Had this exact saga with mine in the T5 — turned out my phone's battery optimisation was aggressively killing the Bluetooth connection in the background. Go to Settings > Apps >...
