5. Solar Market Segmentation
Rooftop solar installations No fuse needed up to 3 strings which represents the main market
Rooftop solar installations with a string protection combiner box usually directly connected to the inverter 1000VDC Market
Ground solar installations
with string protection combiner boxes
sometime recombiner boxes
main fuses in the DC side of the inverter or in a separate DC combiner box will transition from 1000VDC to 1500VDC within 2-3 years
