Table 9.1 Maximum 1-way wire distance for 48V systems, stranded copper
Notes:
• The specied wire length is for a pair of conductors from the solar or battery source to the
controller (1-way distance)
• Shaded cells in the table indicate that the current exceeds the ampacity of the wire for a
given ambient temperature as dened in the following table:
Wire Ampacity* Key
Exceeds wire ampacity at 60°C ambient temperature
Exceeds wire ampacity at 50°C ambient temperature
Exceeds wire ampacity at 40°C ambient temperature
Exceeds wire ampacity at 30°C ambient temperature
