I learned from Outback yesterday that an important step in using this RS
initiator is not described in the directions. The prewired GFI needs to
be removed and the conductors connected to their supplied RTB breaker
that is supposed to be located in the same slot. The GFI function is
inthe combiner box.
Has anyone found Outback instructions describing this? The person I
worked with on the phone yesterday could not find any directions to this
effect. Chris

Yes I had also heard from Outback that AC Coupling not supported.
Too bad because the AC coupling load center was slick setup and
integration.

Larry,
I recommend considering retrofitting the SolarEdge “StorEdge”
Li-ion battery. It’s a high-voltage battery on the PV side of the
inverter. We have a few out there now for a few months without a
problem. Really like the design concept of the storage on the PV
side, increasing system efficiency.
We’ve done quite a few AC-coupled systems, which Outback FX,
Outback Radian, and SMA Sunny Island/Sunny Boy. The Outbacks
require a cutout relay. We won’t do Radian AC-coupling any more,
as the setup, documentation, and support is a royal PITA, and have
had failures in the “ROCB” automatic cutout breaker. Even when the
ROCB doesn’t fail, it often cuts out when it isn’t supposed to,
like at the start/end of a float cycle. My understanding is that
Outback doesn’t support AC-coupling any more with the Radian.

Does anyone have a recommendation on a battery based inverter to
AC Couple with a Solar Edge 11400A-US Inverter that is already
installed?
I have been working a lot with the Schneider Conergy XW+
Inverters for off grid but have no experience AC Coupling them
with a Solar Edge Inverter
Any recommendations?
Thanks
