From engineer:

The panel is a 200 Amp panelboard with a 200 Amp breaker.

A load side connection, via a backfed breaker in the sub-panel, would not be code compliant.

The continuous current of the X22 microverters is 1.33 amps.

1.33 amps x 26 microinverters= 34.58 amps

34.58 amps x 1.25= 43.23 amps

The maximum allowable backfeed if the main is a 200 A with 200 A main breaker is 40 amps.

I would have to draw this as a "supply side connection" with an additional sub-panel for PV combining.
