Added mains hookup

The geeky electrics work continues. I've now bought a smart charger, and a mains hookup (not a snazzy one, just a mains reel with a 16A plug on the end). As well as powering my charger, I've also adapted my switches and things so that my mains socket and TV can switch between using the invertor and mains supply.

Here's the geeky wiring diagram!
