Trumpy:
A 'basic' on US solar....
The solar output (AC) is utility tied either thru a backfed cb, or a 'line tap' ahead of the main cb. The output is dependent on utility voltage; hence NO utility voltage, no solar output into the grid.
A system with DC output from the panels is connected to an inverter, them a disconnect, and then the utility tie.
A system with micro inverters has the AC output into a solar sub panel, then the disco (if required) then the utility tie.
The technology is changing very quickly, with new equipment which reduces the "parts"; soon it may be an 'all in one'
Note that there are many variations, including the Tesla energy storage system, which is showing up sporadically.
