Solar combiner box
Anyone made there own combiner box if so how and what did you use. Am solar has one for $80 but I am sure it can be built for a lot less.

I used a 2" conduit LB since I was going to pull through conduit all the way to the location on the exterior for entrance. A 4" junction box serves the same purpose. There are gasketed box entry fittings available. I use ones that accepted two MC4 wires and filled the center with caulk, once pulled.
