Hello,
I recently posed the question to Solaredge tech support, wondering if their inverter, in this case a 20kw 480 3-phase, would have any issues if it were connected to an AC panel backed up by a generator. They told me no problem, for the inverter's anti-islanding will work if it sees the "generator frequency" and therefore will not try to push PV power to the panel. But isn't 60 hz, 60hz regardless of origin? There's got to be more to it than that. I question this because I asked the same to SMA several years ago and they were hard-set against connecting Sunnyboys to a panel with generator backup, so I always would establish the point of interconnection upstream of the generator feed. Comments? Thanks. Kirk Herander VT Solar, LLC dba Vermont Solar Engineering NABCEPTM Certified Inaugural Certificant NYSERDA-eligible Installer VT RE Incentive Program Partner 802.863.1202
