Smart PV

How does a traditional solution ensure security on the PV DC side?

Choose three
  • A Fuse
  • B DC combiner box
  • C Manual disconnect switch
  • D AC switch
Explanation

Traditional PV DC-side safety is provided through fuses for string overcurrent protection, DC combiner boxes that consolidate strings and incorporate DC-side protection, and manual DC disconnect switches for isolation. An AC switch applies to the inverter/grid AC side, not the PV DC side.
