Been lurking, thought I'd join up.

We're in the initial planning stages of a DIY Grid-Tie project. The Solar Array will be installed on a machine shed roof. The attached sketch should show this but,

1) The main power from utility first goes from power pole/transformer to the "House" Breaker Box.

2) Power from the "House" box goes underground to the "Shed" Breaker Box (please note, Shed boxes main breaker is located in "House" box)

3) From what I understand, I can run the A/C from Inverter to "Shed" box, which in turn takes the solar generated power to the "House" Box (we utilize the same underground wiring), in which we tie in to a reverse meter

4) of course there is a bit more to it, just wanted to keep it simple for an explanation

Are we on the right track? Please review attached Wiring Plan and Breaker Box photos. THANKS!

What size system are you thinking?

Do you know the gauge of wire from the main panel to the shed?
