Jay, I assume you mean pitched roofs, or not readily accessible flat roofs. This particular project happens to be a flat commercial roof, but with no permanent ladder or hatch. I really didn't have to use the MNPV6-AC's, but it made sense in this case (excluding the access issue).
Looks like my options are to remove the combiners or install a permanent access. Neither are fun options.
