If all their reps and retailers are as serious, that’s a good sign.

After I contacted the local installer, this morning I got a call from a Generac representative, John. (He also mentioned contact with the ARRL.) He told me the system has been disabled pending installation of new "optimizers", which are on back order until October. The homeowners are being compensated for loss of solar production in the meantime.

John claimed to have had experience with similar situations and felt that the source of the interference was the optimizers, rather than the central inverter. He also seemed to be familiar with other mitigation measures, such as installation of ferrite cores on interconnecting cables. In any case, we will perform a test after the new optimizers are installed, and go from there.
