Duo Battery Charge Controller RENOGY 10A | 20A Pulse Width Modulation Solar Charge Controller Manual 1 2775 E. Philadelphia St., Ontario CA 91761 1-800-330-8678 Version: 1.
Important Safety Instructions Please save these instructions. This manual contains important safety, installation, and operating instructions for the charge controller. The following symbols are used throughout the manual to indicate potentially dangerous conditions or important safety information. WARNING: Indicates a potentially dangerous condition. Use extreme caution when performing this task.
Battery Safety Use only sealed lead-acid, flooded, or gel batteries which must be deep cycle. Explosive battery gases may be present while charging. Be certain there is enough ventilation to release the gases. Be careful when working with large lead acid batteries. Wear eye protection and have fresh water available in case there is contact with the battery acid. Carefully read battery manuals before operation.

General Information The Renogy PWM1020CC-DB features dual battery charging capability making it great for RVs, caravans, and boats. With its advanced PWM charging technology, your batteries will be protected from discharging and over-charging. This controller is specifically designed for mobile off-grid applications supporting 12V deep cycle battery varieties such as sealed lead acid, gel, and flooded.
Optional Components *The PWM10A/20A-Dual Battery charge controller is shipped by itself, without any additional components. Optional components that require a separate purchase: Remote Temperature Sensor (TS-R): Measures the temperature at the battery and uses this data for very accurate temperature compensation. The sensor is supplied with a 6.6ft cable length that connects to the charge controller.

Installation General Installation Notes Read through the entire installation section first before beginning installation. Be very careful when working with batteries. Wear eye protection. Have fresh water available to wash and clean any contact with battery acid. Uses insulated tools and avoid placing metal objects near the batteries. Explosive battery gasses may be present during charging. Be certain there is sufficient ventilation to release the gasses.
Wiring Recommended tools to have before installation: Flathead Screwdriver Multi-Meter WARNING: Connect battery terminal wires to the charge controller FIRST then connect the solar panel(s) to the charge controller. NEVER connect solar panel to charge controller before the battery. CAUTION: Do not over-torque or over tighten the screw terminals. This could potentially break the piece that holds the wire to the charge controller.
Battery 2 1 3 Connect Battery 1: Refer to Figure 4, Connect the negative terminal of Battery 1 to the negative terminal of the charge controller under the Battery 1 logo. Then connect the positive terminal of Battery 1 to the positive terminal of the charge controller under the Battery 1 logo. Connect Battery 2: Repeat the process described in last step for Battery 2. Figure 4 shows the connections. If you are not planning on installing a second battery you can skip this step.
Solar Panels 2 1 3 Connect the solar panel(s): Connect the negative PV lead of the solar panel to the negative terminal of the charge controller under the solar array logo. Then connect the positive lead of solar to the positive terminal of the charge controller under the solar array logo. Make sure the solar module(s) voltage and current do not exceed the ratings of the charge controller.
Temperature Sensor (if applicable) 1 Connect the Remote Temperature Sensor (Optional): If you purchased the remote temperature for your batteries, you can connect it in the remote temperature terminals depicted in Figure 4. If you are not planning on using this sensor, you can skip this step. Note: When the RTS is not present, the controller will calculate the data from the local temperature sensor. The controller will obtain data from RTS automatically when present.
Operation Battery Type To select the battery type press the SET button on the controller a few times until the “Battery Type” LED lights up. Press the setting button again and hold it for 5 seconds until the digits start flashing. Press the setting button again to choose the battery type as described in Table 1. Leave it in this position, and it will stop flashing after a few seconds. The controller has recorded the battery setting.
Number 0 1 2 PWM Charging Frequency 25 Hz (pre-set) 50 HZ 100 HZ Table 3 Charging frequency settings Battery #1 Status LED Indicator Battery #2 Status LED Indicator Figure 5 Charge controller LED indicators Battery Indicators The LED indicator shown in Figure 5-2 will turn on whenever sunlight is available for battery charging. Under normal charging conditions, the charging LED will lit Green at all times.
Troubleshooting Check all connections to ensure they are secure and clean Check polarity of the battery connection and make sure the battery generates at least 6V Ensure the solar panels are exposed to sufficient light – ideally position them to face the sun directly If charge controller states that there is short-circuit, please ensure that the panels are connected correctly, and that the wires at the terminals are not touching each other.
Fuse from Controller to Battery Controller to Battery Fuse = Current Rating of Charge Controller Ex. 20A Dual Battery CC = 20A fuse from Controller to Battery Fuse from Solar Panel(s) to Controller Ex. 200W; 2 X 100 W panels Series: Total Amperage = Isc1 = Isc2 = 5.75A * 1.56 Fuse = minimum of 5.75A * 1.56 = 8.97A = 9A fuse Parallel Total Amperage = Isc1 + Isc2 = (5.75A + 5.75A) * 1.56 Fuse = minimum of 11.5 * 1.56 = 17.
