Can someone explain to a stupid old man how these breakers do anything other than cut AC/DC power(s) to the inverter in the event of an catastrophic event within the inverter, as well as serving as disconnects?
I understand how they would trip if there were shorts on the feed lines but what about the big battery cables, the 2 - 2/0's to buss bars and the 4/0's to the server rack buss bars? What protects those cables?
I just dont see how those XP breakers negate the need for PV disconnects before the inverter and Class T fuses on the battery lines. What am I not seeing here???
