That is what is there now. Not that brand, but that device. The problem is that there are 12 three phase units and 18 single phase, for a total of 500kW, all exporting to secondary lugs on the XF. The units end up monitoring each other rather than the utility.For PV, there is a unit for the purpose. SMA's Sunny Island is one of them.
They can also combine and control power from other sources besides PV.
