Use of Enphase IQ7+ with Multiplus II in California

Referring to the Documentation Note "AC-coupling and the Factor 1.0 rule" the Multiplus II is shown connected with PV Inverters to allow a grid-tie configuration. Can this configuration work with the Enphase IQ7+ modules (PV Inverter)?


Will this allow these two conditions to exist on a 60 Hz system?

  1. Multiplus-II will use solar power (through the Enphase IQ7+) to charge 48 Vdc battery bank when grid is not present.
  2. Multiplus-II will allow Enphase IQ7+ modules to back feed to the power grid when the grid is present.

I’m also curious about this as well as setting up a multiplus + CT coil to help my house have net zero power flow from the grid at night.
