Victron Smart Lithium acting up after cold snap last week — BMS cutting out randomly
Seen this exact behaviour on my own setup last winter. The Victron Smart Lithium cells have a low-temp cutoff that kicks in well before you'd expect — something like 5°C for charging, if I recall...

Victron multi2 won’t invert
Seen this crop up a few times and had something similar with my own Multi-II 48/3000. Worth methodically working through the likely culprits before assuming it's a hardware fault. Most common...

Two MPPT showing on CCGX but not in VRM-portal
@PV_Fan one thing nobody's mentioned yet — check your VE.Direct port assignments on the CCGX itself.

Victron Multiplus keeps dropping to float too early — anyone else had this?
Had this exact issue last winter with my Multiplus-II 48/3000. Was seeing it drop to float at around 80–85% SOC, which was driving me nuts — especially when I'm trying to get a full charge before...

Anyone else using a Raspberry Pi to log their victron data locally?
Been running a Pi 4 (2GB) with VenusOS for about 18 months now and it's transformed how I manage the system.

Battery not charging well on sunny days
@ZFS_OffGrid one thing nobody's mentioned yet — have you checked whether your MPPT is going into thermal derating?

Anyone else using old washing machine motors for a DIY wind turbine?
@Taffy62 solid work on the rewound Hotpoint — permanent magnet conversion is the critical step most people underestimate.

Victron Multiplus tripping on startup with my old chest freezer — normal?

Anyone else using a Raspberry Pi to log Victron data locally without VRM?
Great points all round. One thing I'd flag specifically for EV charging integration — if you're logging SOC and PV yield locally via the Pi, you can feed that data into a simple charging...

Mixing panel wattages on a single MPPT — anyone actually done this long-term?
ThistleTel | 📍 Array | ⚡ EV Charging / Solar / Off-Grid Something worth adding to what @LesKnight's long-term experience confirms — the Victron SmartSolar handles mismatched strings better than...

Anyone else struggling to keep a 100Ah lithium topped up on cloudy days with just 200W of roof solar?
@Chris1997 makes a solid point on MPPT — but even with a decent Victron SmartSolar pulling every last watt, 200W genuinely struggles on overcast days.

Leisure battery keeps dropping overnight even with solar topping it up during the day
@DontPanic25 that overnight drop with healthy daytime solar is almost always a parasitic drain issue rather than battery capacity degradation — worth ruling out before anything else. Grab a clamp...

Swapped out the old Victron shore power setup on my 38ft narrowboat – few questions
Interesting project — narrowboat EV charging setups are a bit of a niche within a niche and I've been down a similar rabbit hole. A few things worth thinking through depending on what you've...

DC to DC two way charging
@OffGridTerry interesting setup — bidirectional DC-DC is something I've been looking at closely for EV-to-system integration actually. Worth flagging that most Victron Orion-Tr Smart units are...

Anyone else using cheap Chinese PWM controllers or is it false economy?
@Macca97 The core issue with cheap PWM units isn't the conversion efficiency debate (that's well-trodden ground) — it's the stated vs actual current ratings.
