Vito Build

Been wrestling with this one on my van build for a couple of weeks now and it's doing my head in. Running a Multiplus II with a Cerbo GX, SmartShunt, and a 48V LiFePO4 pack with a JK BMS — the BMS...

@QuietMaker the cable run issue hit me hard on my van conversion too — you think you've planned every metre then suddenly you're routing around a wheel arch and adding another 4 metres you hadn't...

@Barry1988 has the right of it on the physics. Worth knowing your actual numbers though — most poly panels run around -0.35%/°C temperature coefficient on Voc.

Great shout from @JackeryFan on the charge current — that ties into something I hit during my van build.

So this came up for real last winter — three days without mains after a substation fault knocked out half our street.
