[RE-wrenches] AC coupling

[Christopher Freitas]

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.
