This is why the frequency shift AC coupling such as found with SMA and others is a nice solution as the amount of incoming power from the grid tied inverters is regulated allowing for healthy multi stage charging. <br>
Another thing to consider if using the Outback Ac coupled solution is that your DC coupling options becomes limited in the same load center....<br>

The FNDC will also over ride the timers if all fully charged parameters are met. It has the advantage of being able to safely use a back up generator in the system and will physically disconnect from grid and the AC coupled inverter before connecting the generator.

I would like to see a wiring diagram and know what components from Outback you used with SolarEdge . I have been told variously that SolarEdge does not approve AC Coupling and that they have approve it , depending on who I get on the phone . SolarEdge and Outback have no official diagrams or components list that I can find . I would like some help here as we are in Hurricane season in Gator Land !<br>
