I ventured over to my neighbor this afternoon and spoke with the site
supervisor. The system being installed is the dreaded Solar Edge, complete
with DC-DC converters ('solar optimizers') on each 410 watt PV module and two
central inverters. It is a large rooftop system comprising at least 30 PV
modules. My hope at the moment is that the Solar Edge optimizers and inverters
are the beneficiary of Steve, W1EMI's work with that company to get them to
clean up their equipment designs for RFI.
I've got about a month of time before the system is given the interconnect
go-ahead by the local electric utility, and I'll be adding to my records of
band noise levels as a function of time-of-day.

Subject: [RFI] Experience with PosiGen Solar?

I discovered in walking the dog this morning that my neighbor 400 feet to the
north is installing a PV + battery system. The contractor is PosiGen Solar.
After visiting the PosiGen web page, I can't find any technical information
about their PV architecture (microinverters vs central inverter) and central
inverter for the battery.
Anyone on this list know of this company and any technical details?
I may venture over later today once more of the system is installed to talk to
one of the site supervisors.
Thanks in advance, and 73,
Mike, K8CN
