Ok, I saw your link with the Airtap title and put the two together. I see what you are saying now.

Yeah, if you use 120vac, you can use a cheap timer.
The best one I've used lately is this model.

I'm planning to use one of my transfer switches to supply inverter output power
(with a Timex timer) to one of my 'day time' loads.. Just need to hook it up..

Had a timer on WH for years, then poco quit the nighttime lower rate. HAve separate kw-hr meter on wh also. So disconnected timer (for use somewhere else)

Built box around wh with R25 insulation - went away for 2 weeks and only used 2k kw-hrs. Timer with insulation would gain almost nothing with added insulation.
