I have a pond pump and I was all set to do something similar buuuut no AC on the side of the house. It’s like 85’ to the nearest outlet and that is in front of the house, 200’ to the one in the rear.
I was thinking about what it would take to make a solar rig
Panel, battery, inverter.....
Might be cheaper (and a lot easier) to hire an electrician and get an outlet where you need it. One can never have too many outlets.
