The IMO FireRaptor units are as far as I know immune to any interference from charge controls or inverters. It does not rely on wireless or power line communications. It is simply a hard wired module level disconnect that runs on 24VDC. It has two-wire daisy chain cables between them, with a nice connector, and MC4 for the module and string wiring. OutBack and OutBack distributors are now selling them.
