Does anybody have any experience with PVP 1800 or PVP 2000 solar power inverters, manufactured by PVPowered LLC? I've isolated them as the RFI producers causing S8 to S9+30 dB noise at my house, 0.2 miles away. PG&E also indicated that they're "taking out the entire HF band." Any help appreciated, 73 de Donald AE6RF
