Advise sought for large off grid PV system; 480 volt 3-phase [RE-w renches]

[Larry Crutcher]

Steve,

Have you ever AC coupled a Sunny Boy after the step down transformer? I would think that power should flow bi-directional through the transformer and back to the SI inverters. Our site needs this capability due to space limitation if it would not pose a problem to the SI sensing the SB's and maintaining control over the grid.

Thanks,

Larry Crutcher
