excellent question mark... and one which has been on my mind as well, being most of my work is bbgt. todd On Thursday, March 1, 2012 11:37am, "Mark Frye" <[email protected]> said:
Folks, I have a residential grid-tied customer in a net metered utility with a favorable TOU rate. They could use about 10 kW of PV to offset 100% of their usage. But, they also complain about regular power outages in their neigborhood. They don't want a generator. With reliable AC coupling now available, do we yet know which is the more advantagous architecture; grid-tied, battery-based inverter w/ PV on the DC side via charge controllers, or grid-tied, battery-based inverter w/ PV AC coupled via grid-tied, utility-based inverter?
