I used this for a solar combiner box for two DC 500v strings using the included DIN rail for two breakers and two lightning arrestors. The box is sturdy, painted well, has a removable standoff plate, removable access plate on the bottom, good and plentiful grounding points, a nice lock and a rain/snow shelf. The only thing I had to add was a ground bus block for my lightning arrestor grounds. This is real value for the money. I might buy another to replace a plastic box I used elsewhere. One thing to note, any conduit entrances will need to be drilled. there are no knockouts. I plan on drilling the large access plate on the bottom for everything.
