Intelligent Integration: Integrated DC/AC disconnect switches, and up to
15 fused string inputs eliminate the need for external DC combiner boxes,
simplifying installation and the need for DC BOS equipment. The rapid
shutdown version wirebox has integrated the rapid shutdown PLC
transmitter, requiring no field wiring, and eliminated the negative DC fuses
in accordance with the 2017 National Electric Code.
