Page 3: Installation Overview
Controller prevents overcharging by limiting the current flowing into the batteries from your solar array. The GP-PWM-30 is a 12-volt flush mounted photovoltaic (PV) charge controller rated for a continuous solar current input of 30 amps. The GP-PWM-30 uses Pulse Width Modulation (PWM) technology and a unique four stage charging system that includes an automatic equalize setting to charge and protect your battery bank (for flooded batteries only). The GP-PWM-30 features an LCD digital display that shows the charge current of the solar array, system battery voltage and battery capacity. -
Page 4: Specifications
The total rated Maximum Power Current (Imp) of the PV input should not exceed 30 amps. The GP-PWM-30 will limit PV current above 30 Amps. Although the GP-PWM-30 will accept PV current greater than 30 Amps for a short duration, damage may occur if the GP-PWM-30 operates continuously with greater than 30 Amps of PV input. -

PV strings in parallel. The resulting Do not exceed the system Imp current is not to exceed 30A. The GP-PWM-30 amp voltage of the array is the rated open circuit current and max voltage (Voc) of the PV array and is not to voltage ratings exceed 28V. -
Page 6: Tools And Materials Needed
The wire from the solar array most commonly enters the RV through the fridge vent on the roof or by using the Go Power! Cable Entry Plate (sold separately) that allows installers to run wires through any part of the roof. PV connections should connect directly to the controller. - Page 7 Wiring the GP-PWM-30. Wire the GP-PWM-30 according to the wiring schematic in Section 6. Run wires from the solar array and the batteries to the location of the GP-PWM-30. Keep the solar array covered with an opaque material until all wiring is completed.

The terms SEALED/GEL, AGM and FLOODED are generic battery designations. Choose the charging profile that works best with your battery manufacturer’s recommendations. Auto Equalize: The GP-PWM-30 has an automatic equalize feature that Note will charge and recondition your batteries once a month at a higher voltage to ensure that any excess sulfation is removed. Auto equalize is only available for flooded batteries. -

Page 19: Troubleshooting Problems
There may be a slight difference between the battery voltage displayed on the GP- PWM-30 display and the battery voltage measured at the battery terminals. When troubleshooting using a voltmeter, check both the battery voltage at the GP-PWM-30 controller terminals and battery voltage at the battery terminals.
