Kirk -
Yes it does require the additional relay as a minimum for disconnecting the AC coupled battery-less grid-tie inverter. I did not think of that as a protective relay (which is a term utility engineers use for a protective device intended to prevent islanding of a generator usually - it is a relay with its own voltage and/or frequency sensing circuitry built in). The point I was trying to make is that its pretty straight forward - just need one 12vdc coil AC relay between the OutBack inverter and the battery-less grid-tie inverter - unless you are also wanting to have a back-up generator as well which will then require an additional manual or automatic AC transfer switch... Still pretty simple compared to many of the off-grid systems which most of the wrenches have installed.
