A common point of connection for a PV system is thru a dedicated CB to the panel's busbar. When feeding a dwelling's panel busbar, the sum of the supply breakers can be up to 120% of the rating of the busbar.
In my way of thinking, if I have a 125 amp busbar protected by a main breaker of 100 amps, this provision would allow a 50 amp PV breaker. 125 amps X 1.2 = 150 amps....150 amps minus 100 amps = 50 amps. Correct?:-?:smile:
