The “eco” power sources need to be synced with the grid frequency. In the USA, if the grid is off by as little as 0.5 Hz, it is enough to trip safety circuitry.

Agree. My solar inverter beeps and disconnects from the grid whenever it detects that the grid power deviates too far from 60 Hz. That happens once every 2 months or so. The idea is to protect my home's electrical system from dirty power.

I'm told that refrigerators are most susceptible to dirty power.

“My solar inverter beeps and disconnects from the grid whenever it detects that the grid power deviates too far from 60 Hz”

Why doesn’t your inverter grid follow? Mine will adjust phase to follow all the way down to 59 hz or lower. Inverters don’t have reactive power requirements they can follow any phase angle or hertz with ease. No home has an inertial load that needs reactive power , even AC compressors the largest reactive loads in a residence are a fraction of the total load. I have two large compressors and both can be driven directly from my inverters with little loss in power factor. The only reason my inverters will trip is the grid is pulling more than they can push out and that’s gonna be a phase angle well more than 1hz which means the grid itself is down they will follow deep into 59.2 hz. I don’t habe small systems I crossed 100 kw recently on property , the windmill is up now a 50kw variable pitch on a 30 meter monopole.
