    2. Complete the installation of the solar modules. If this GP-PWM-10-FM was purchased as part of a Go Power! Solar Power Kit, follow the Installation Guide provided. Otherwise, follow manufacturer’s instructions for solar module mounting and wiring.
  • Page 10 Wiring the GP-PWM-10-FM. Wire the GP-PWM-10-FM according to the wiring schematic in Section 6. Run wires from the solar array and the batteries to the location of the GP-PWM-10-FM. Keep the solar array covered with an opaque material until all wiring is completed.
  • Page 11 6. Mounting the GP-PWM-10-FM. Mount the GP-PWM-10-FM to the wall using the included four mounting screws. IMPORTANT: You must set the battery type on the GP-PWM-10-FM before you begin to use the controller (follow steps in Section 7). The default battery setting is for AGM/LiFePO batteries.

  • Page 12: Wiring Diagram

    IMPORTANT: This diagram is valid only for version 1.5 and newer. Version 1.4 and older have different terminal locations. The GP-PWM-10-FM Maximum 12.5A rating is based on a 10 amp total maximum short circuit current rating (Isc) from the parallel solar modules nameplate ratings.
