Why not hang the panel out the window like the AC unit?
Rev 2 needs better hinges or straps out the window.
Step 1: Panel, Scrap Wood, Pipe Strap
Got scrap wood on both ends of panel. Also Scrap wood inside window with 2 straps out to the panel.
The closed window essentially holds the straps, the inside piece of wood is good for initial setup.
Step 2: Leg for Angle
Probably should bury a piece of wood against wall and screw angle leg into that.
A gust of wind might be able to pick panel up?
Step 3: Charge Controller and Battery Box
I got an inline fuse cable and battery tender cable with fuse from Pep Boys. I followed wiring schematic from Renogy. (They have boss documentation btw.)
I mounted controller to lid of battery box and we are good to go.
