Plan to use 4" angle iron (aluminium) screwed to the roof and 1" angle on the panel.

Questions:
1. Any problems with the panel that high (4 & 1/2 inch)?

2. Any problems with the controller (Eco Worthy 20) in the battery compartment like BLF showed a picture of his?

3. What about 110V house light switches for panel and battery disconnect?

4. Is there a place Atlanta GA to pick up a panel & avoid the shipping cost?

1) No problem with my 4x4 angle, 1/4" thick, 245W 40lbs panel, mounting hole 3/4" from the top of the angle. Here. People told me that I overdid it, so with 1/2" thick aluminum you don't have to worry. Remember to leave 3 deg - 4 deg tilt on the panel, this is necessary to shed the water and debris. Mine is tilted higher on the photo, I was toying with "real tilting" that involved support legs, but decided that it wasn't worth the trouble.

2) Eco has an internal temperature sensor, not a remote one. So it should better be in the same temperature zone (or close) as the batteries. If you can't meet both temperature proximity and the need to keep it away from fumes, you have 2 choices:
A. Get a controller with remote temp sensor
B. Get AGM batteries.

3) No. Get 12V breakers or DC fuses for panel and controller. For battery disconnect there is nothing better than Bluesea 3-position selector switch. Those that look like a kitchen timer.
