[RE-wrenches] AC coupling

[Kirk Herander, VSE]

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?

Thanks for the nice comment. 

 

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.
