[RE-wrenches] AC coupling with SolarEdge

Brian,
Thanks, it came through perfectly! Am I correct to assume that the SE
inverter will only respond to a PRI Port input signal to ramp output up and
down and not a frequency shift? I'll have to check if there is someway to
use that function with the XW. When I spoke with SolarEdge support, they
said they are not supporting this function anymore. Do you know if that
means SE won't supply technical support or that their inverters don't have
that capability any more?

> Hi all,
> Apparently SolarEdge is no longer officially supporting or warranting AC
Coupling - maybe because they now have the StorEdge option (has anyone
actually seen one for sale and/or operating). In any case, since I have
sold prior to missing that memo and am now in the position of installing a
battery backup system using an SE5000US and a Schneider XW5548, I am
needing to figure the details out without any support from either Schneider
or SolarEdge (SolarEdge tech support referred me to Outback tech support
saying Outback has recommendations for AC coupling with SE, but the techs I
spoke with at Outback are vague at best when talking about AC coupling with
any inverter and even less forthcoming when talking about SE).

and what those parameters are? I will install a failsafe relay to
disconnect the SE inverter upon high battery voltage, but it would be
useful to know what, if at all, the set points for power limiting are in
the SE inverter. Any info or leads would be appreciated.
