Some utilities require lockable blade style disconnects while others will accept the backed breaker in a load panel(if outside) as the photovoltaic AC system disconnect. My question refers to situations where grid tied inverters and the AC point of connection are both inside a dwelling. Specifically, if a grid tied inverter is located inside a garage and it's output is connected to a back fed breaker in the main panel (also in the garage), can the utility disconnect at the meter serve as both the utility and PV system AC disconnect? I see nothing in the NEC that says the PV system's external AC disconnect has to be independent of the utilities' disconnect. Can this one breaker act as the disconnect for two sources of power? Any thoughts would be appreciated. <div><br><div>
