Re: [RE-wrenches] Combining Multiple Inverters

What am I missing here? In the 2014 NEC, 705.21 seems to indicate that every inverter needs to have its own AC disconnect. Most inverters only have integrated DC disconnects (SMA, Power One, Fronius) as I recall. Or has this been interpreted to only apply to the DC side of the system? Since
