PWM-30-UL Installation: Choosing a Location

**Choosing a Location to Install GP-PWM-30-UL** The GP-PWM-30-UL is designed to be mounted flush against a wall, out of the way but easily visible. The GP-PWM-30-UL should be: * Mounted as close to battery bank 1 as possible * Mounted on a vertical surface to optimize cooling of the unit * Indoors, protected…

Important Safety Instructions

![][1] **Disconnect all power sources** Electricity can be very dangerous. Installation should be performed only by a licensed electrician or qualified personnel. ![][2] **Battery and wiring safety** Observe all safety precautions of the battery manufacturer when handling or working around batteries. When charging,…

PWM-30-UL Installation: System Voltage and Current

The GP-PWM-30-UL is intended for use at 12 VDC system voltage and is rated for a maximum continuous DC input current of 37.5A and input voltage of 35VDC. Per the National Electric Code (NEC) article 690.7 and 690.8, PV module nameplate ratings must be multiplied by required values (typically 1.25 for both voltage and…

PWM-30-UL: Installation Tools & Materials

**Tools and Materials Needed** * Flathead Screwdriver (for wire terminals) * Philips Screwdriver (for mounting screws) ![][1] If the GP-PWM-30-UL Controller was purchased with a Go Power! RV Solar Power Kit, then UV resistant wire is included. For instructions regarding the Go Power! RV Solar Power Kit installat…

PWM-30-UL Installation: Low Voltage Disconnect Function

**This article relates to the USB Port, and Inverter Remote Signal** To prevent the battery against over-discharge this function automatically switches off the USB output port when Battery 1 voltage is lower than 11.0 VDC. If a compatible inverter is connected and set to remote mode, the controller will also switch o…

PWM-30-UL Installation: Supported Battery Types

The GP-PWM-30-UL is suitable for use with lead acid batteries (vented, GEL, or AGM type) as well as some lithium iron phosphate (LiFePO4) batteries that are supplied with a Battery Management System (BMS).

PWM-30-UL Installation Introduction

A Solar Controller (or Charge Controller / Regulator) is an essential component of your photovoltaic solar system. The Controller maintains the life of the battery by protecting it from overcharging. When your battery has reached a 100% state of charge, the Controller prevents overcharging by limiting the current flow…

GP-PWM-30-UL Errors: Over-Voltage

If the GP-PWM-30-UL experiences a battery over voltage (>15.5 VDC) on battery bank 1, the controller will stop operating, and the display will begin to flash with all icons. The controller will resume operating when the voltage drops to a normal level <15.5 VDC. Icons Displayed: All symbols ![][1] The controller doe…

PWM-30-UL: Dual Battery Bank Charging

The controller considers multiple batteries wired together in series or parallel, with a single 12 volt output as one battery bank or a single battery. A second battery would have to power separate circuits such as a starter battery or a separate battery for your slides. **Charging Process** Exactly how and when Bat…

GP-PWM-30-UL Installation: Single Battery Wiring Diagram

**Single Battery Wiring Diagram** Use the following wiring diagram if you are using the GP-PWM-30-UL to charge only one battery. Connect your battery to the battery 1 terminals on the solar controller. ![][1] The GP-PWM-30-UL Maximum 37.5A rating is based on a 30-amp total maximum short circuit current rating (Isc)…
