WARNING: When the power of PV module is greater than the rated charging power, and the maximum open-circuit voltage of PV array is more than 60V(XTRA**06N)/100V(XTRA**10N)/150V(XTRA**15N) lowest environmental temperature), the controller may be damaged.

  • Page 11: Wire Size

    2.3 Wire Size The wiring and installation methods must conform to all national and local electrical code requirements.  PV Wire Size Since PV array output can vary due to the PV module size, connection method or ＊ sunlight angle, the minimum wire size can be calculated by the Isc of PV array.
