I made a base for the tower.
I'm not sure how well it will work. I plan to stick it in the ground and pivot the tower up on it. I'll probably have someone stand on it while a couple others raise the pipe, pulling with a rope from the roof and pushing from the ground. It's really just for temporary use at first, unless this site works out well.
I mounted the microcontroller and my homemade I/O board into a box I had kickin around.
I plan to mount this box on the panel with the inverter and all the other stuff which I'm currently setting up.
