dnix71 - Thanks for the info. that's just what I needed. I wasn't sure if low voltage ac was different than standard 110/220.
About 10 ft from the tower is an old 110 ac outlet that has been disconnected for years. It was for a swimming pool and is run in conduit back to the electrical panel. My plan is to run the wire from the tower in a short pc of conduit to a junction box were the 110 plug use to be then at the other end hook it to the charge controller.
Thanks again !
George
