I'm in unfamiliar territory on this particular matter. I have a case involving a privately owned, off grid power system and we want to parallel two 120 Vac sources; the AC main (sine wave) and a small sine wave inverter. We only need 100 to 200 watts from this 120 Vac inverter. I've got control...
I need to grid-tie a bunch of about 50 small inverters that process DC input of say, up to 17 Vmp and 6.5 Imp and back feed this through a small sine wave inverter rated to +/- 120 watts into an existing 120 VAC / 60 Hz AC grid. The AC grid is not a public utility, rather the end-user's AC...
