This summer I've been working on an area in a barn to place an inverter and batteries. I have a large metal barn 175 ft from my home, with a row of cedar trees next to the barn. So far, inside the barn I poured a concrete pad 7ft x 12ft. I've enclosed an area of the pad 7 x 8. I'm going to place 2 small generators, stacked, on the other part of the pad, which is still in the barn. This week I rented a trencher and trenched from the barn, through the cedar trees, across the driveway and to the side of my house. In the trench, I placed two 2in PVC conduits. As I laid the first conduit, I ran heavy poly baler twine as I glued each joint. Then pulled 5 wires of #3 copper. I already had the copper wire from a building I salvaged several years ago. I'm going to parallel 2each of the #3's. That way I know I'll have the capacity for about anything I want to do. One #3 would have been sufficient for 240v at 80 amps, but I had the wire. I'm going to run Cat5 wire through the other conduit for computer, security cams, telephone. I separated the conduits with about 1 ft of dirt. I also placed in the trench a 3/4 inch poly line for propane, and connected to my propane supply line. Now I'll have propane the the gens also. A lot more work to do, as I can. Next up, mounting inverter, disconnects, etc., and mounting gens. Wife doesn't have a clue of what I'm doing, or why. Totally oblivious.
