Reply by Deano13: @BayJason 3kW should be workable for a Leaf depending on your daily mileage. The key thing to remember is you're not charging directly from panels — you're cycling through the...

Deano13 replied: @EllaDixon71 One thing nobody's mentioned yet — have you checked your panel voltage under load in cold weather?

Deano13 | 847 posts This is completely normal behaviour for LiFePO4 unfortunately @TerryScott72 — the chemistry genuinely loses usable capacity as temps drop, it's not a fault.

So I've finally got my roof setup sorted on the Transit, or at least I thought I had. Running two 200W panels wired in series (so nominally 24V system), hooked up to a Victron SmartSolar MPPT...

Something @MandyRoss touched on is worth digging into further — if your BMS is actively talking to the Victron via VE.Direct or Cerbo GX, it can override your manually set charge voltages...

Great thread this. @HighlandExplorer makes a solid point about the inline fuse — catches people out more than you'd think. One thing I'd add that hasn't been mentioned: check your supply voltage...

Nice project, @OldSparky! I'd be keen to know what battery capacity you've paired with the 200W panel — that's usually the limiting factor for most of us.
