Chris,
Pls explain "no additional relays required". I've done an ac-coupled system and used a protective relay because I was told to do so at an Outback workshop by your techs, because the Outback cannot regulate the AC charge current coming from (in this case) the SunnyBoy string inverters. Is this not the case?

AC coupling with the OutBack off-grid inverters and a typical batteryless grid-tie inverter doesn't require any additional transfer switches or protective relays - its actually pretty simple depending on how fancy the battery charging regulation needs to be. It can be very cost effective and worth considering on any projects.
