Maximum One-way Distance and Wire Size
Refer to Table 2-3 and find the maximum current in the left column, and the one-
way distance from the PV array to the XW SCC (or the distance from the XW
SCC to the battery) on the same line, then read the wire size required at the top of
the column.
For equivalent metric wire sizes, consult a local electrician or certified installer.
Important:
Local and national electrical codes must be followed for determining
additional installation requirements.
Table 2-3
One-Way Wire Distance and Wire Size
Maximum one-way wire distance for a < 3% voltage drop assuming 60 A charging
current
12 Vdc application shown
For 24 Vdc systems, multiply distance by 2
For 36 Vdc systems, multiply distance by 3
For 48 Vdc systems, multiply distance by 4
For 60 Vdc systems, multiply distance by 5
Distance in feet (meters)

a.These wire sizes are not approved to be installed in the controller, but may be used external to the
controller (using a splicer block) to reduce voltage drop and improve performance.
