Simple!

You use another breaker and run it's 120v through a photocell detector like
the ones used on sentinel yard lights on a farm laneway. Use the regular
240 volt during the day and the other 120v one through the photocell will
only come on at nights, being out of phase.

Gordon,
You explanation makes perfect sense but it does not explain where we
would get a third pahse from if we need 3 phase power. Any ideas?
