Thats not a bad idea. It seems almost unamerican that the post office is going down but they're an old business in a new world. I mean shit blockbuster got taken out by a redbox.
I would not do 12/12 I would do 18/6, maybe 16/8 if your trying to save some power. Anything is possible but 24/0 just waste power imo I believe the plant defaults into sleep/rest mode for the min. time It needs. which is why they should be given a break, a little rest.
