A solar-power claim. An earlier power-supply architecture.
Aggregate current and voltage sensing, with local controllers for individual inverters.
The technical question
Where had a primary controller already used total AC current and voltage to coordinate multiple inverters, each with its own secondary controller?
The research approach
The research followed the control architecture across neighboring engineering fields. A 1998 power-supply patent describes parallel transverters, common output sensing and local switching control.
Cross-field research
Search the underlying engineering mechanism, then map each element back to the claim.

“Current voltage sensor 22 monitors the total voltage and total current being supplied by one (or more) transverters operating in a particular voltage phase.”Read the reference
The mapping
For limitation 1b, the submission maps sensor 22 and system control module 18 to aggregate current and voltage feedback. Further quotations trace that feedback to the primary control signal.
Scope of this excerpt
This is one passage from a multi-passage mapping. The full chart separately addresses the meaning of a respective DC power source and an alternative photovoltaic reference.
