3. Select wire type and gauge. If this GP-PWM-30-UL was purchased as

part of a Go Power! Solar Power Kit, appropriate wire type, gauge and

length is provided. Please continue to Section 8, “Operating

Instructions.” If the GP-PWM-30-UL was purchased separately, follow

the instructions included here.

Wire type is recommended to be a stranded copper UV resistant wire. Wire

fatigue and the likelihood of a loose connection are greatly reduced in stranded

wire compared to solid wire. Wire gauge should be able to sustain rated current

as well as minimize voltage drop.

Wire Strip Gauge

You will find a strip gauge diagram

on the back of the GP-PWM-30-UL,

which helps you to strip your wires to

the correct length. Insert wire into the

concave slot of the strip gauge until it

meets the back of the Strip Gauge

slot. Mark the length of wire from the

back of the Strip Gauge slot to the

edge of the controller with a pen or

your finger and strip all wires to be connected to the controller to this length.

Suggested Minimum Wire Gauge

(Cable length 25 ft. max. from solar array to battery bank)

Wire Type Wire size min (AWG) Wire size Max (AWG)

Copper Only, 90°C AWG 10 AWG 4

IMPORTANT: Identify the polarity (positive and negative) on the cable used for

the battery and solar module. Use colored wires or mark the wire ends with tags.

Although the GP-PWM-30-UL is protected, a reverse polarity contact may

damage the unit.

Wiring the GP-PWM-30-UL. Wire the GP-PWM-30-UL according to the wiring

schematic in Section 7. Run wires from the solar array and the batteries to the

location of the GP-PWM-30-UL. Keep the solar array covered with an opaque

material until all wiring is completed.

IMPORTANT: All wiring must be in accordance to National Electrical Code,

ANSI/NFPA 70.

4. Connect the battery wiring to the controller first and then connect the

battery wiring to the battery.

5. Torque all terminal screws per the following:
