Attaching a pipe to a conex

[bluedog225]

I’m working on an idea to mount some solar on my conex. One array will be south facing and I’ve about got that worked out.

I’d also like to mount an small 1500 watt array west facing to give me enough juice to run the air con an hour or two longer on solar before I start drawing down the battery.

Geometry is leading me to want to mount a little 6 panel array on a pole. I’ve got some 4” schedule 40 rigid metal conduit and a nice store-bought fitting to hold the array. But I’m having trouble thinking of a good way to attach the pipe to the corner castings of the conex.

I’d appreciate any clever bolt on ideas. I’d need to attach both top and bottom. A 1/2 u-bolt and holes in the schedule 40 is the best I’ve been able to think of. I don’t think a couple of 1/2” holes will cause structural issues. Or will they?

Thanks

Don’t they have flange mounts.

Drill and tap?

I would use flanges like above but, you could weld a smaller pipe to the Conex, slip the supports over the pipes and through bolt it

I would have somebody weld a couple of brackets to the pipe and then you can drill and tap the corner metal and bolt it on.

If your box is not finished on the inside I would drill holes and bolt a sandwich to the shell of the box using the shell of the box as the filling. Apply a gasket and sealer. The mast could be welded to the outer layer of the sandwich.

Sorry for the late response, I didn’t have this on my “watch” list.

Good ideas. Thanks. Not exactly sure what type of flange is being referenced.

I wonder if a big (1 3/4”) shackle would fit in there? The pipe is 4”. I’m having a little trouble figuring out the exact sizes of the conex cast corner holes.

I need to find a rigger with access to a conex. Too expensive to order one that won’t work.
