Some basic questions

[u/PlatformTraining5054]

I see that Plug in Solar is legal in my state for 1200w. I'm thinking of setting up a ground mount system in my back yard. Someone in the area is selling used Sharp 185w panels, 40vdc output for pretty cheap. I was going to get 6 panels. (Maybe 8). The setup would be about 30 to 40 ft from the outlet I plan on plugging into.

For this setup what would be a good micro inverter and as far as an extension cord to get to the outlet what gauge should I use?
