Re: For those who wonder...
I haven't the generation capacity for full self-sufficiency (best I can ), but I figured I might as well make the fullest use possible of my homebrew juice. The intention is to have 5 kWh of storage capacity (the 3kVA UPS I'm looking to use as an inverter needs 48 volts, and a bank of 110Ah traction batteries would hold this much).
I'm going to use a Raspberry Pi as opposed to an Arduino, just so I can do my complicated PID control business logic stuff in a girly, high-level (assembly is for blokes), interpretated language. And for a CGI-enabled web server, so the mobile phone need only be running a web browser.
In the (highly unlikely) event of loss of grid supply, I should be able to run the solar system in "island" mode to charge the batteries, as long as I isolate it totally from the grid and give it a local voltage and frequency source to lock against.
