01
Use a supply-side tap point on the line side of the main service disconnect
02
Route PV through a production meter and dedicated 400 A AC disconnect
03
Keep feeder breakers and loads on the main switchboard downstream of the main service disconnect
Use for commercial rooftop PV projects where the PV output must land ahead of the main service disconnect, typical for load-side limitations or utility supply-side interconnection rules.
