grid tie issue with generator
I am in the engineering phase of putting up ~ 10kW of solar PV. However, I do need an answer to an situation we have here.
Power outages are not uncommon and I require generator backup for watering livestock, keeping freezers going and other essentials. I understand that the proposed Enphase microinvertors system cuts off PV AC power output when grid connection is lost. But what if I turn on the generator? The system I have is a manual transfer switch and I use a power take off generator attached to my tractor. This generator power would "trick" the microinvertors to think that grid AC is available. In the case of a power outage, do I manually turn off solar PV. How is this done? Steve
