Sizing the DC Disconnect for Solar PV Systems

A solar PV system typically has two safety disconnects. The first is the PV disconnect (or Array DC Disconnect). The PV disconnect allows the DC current between the modules (source) to be interrupted before reaching the inverter. The second disconnect is the AC Disconnect. The AC Disconnect is used to separate the inverter from the electrical grid.
