4. Safety Information

Please read all instructions and precautions in this manual before installation. Renogy is not responsible for any damage due to improper installation. Observe the following safety guidelines:

• Ensure all wiring is correctly sized and installed according to local electrical codes.
• Always disconnect the solar panel and battery before working on the controller.
• Do not disassemble or attempt to repair the controller. Contact Renogy support for assistance.
• Install the controller in a well-ventilated area, away from flammable materials and moisture.
• Use appropriate personal protective equipment (PPE) during installation.

5. Installation

The Renogy Wanderer 10A Solar Charge Controller is designed for easy installation. Follow these steps for proper connection:

1. Mounting: Choose a dry, well-ventilated location for mounting the controller. Ensure there is sufficient space around the unit for air circulation.
2. Connect Battery: Connect the battery to the controller's battery terminals first. Ensure correct polarity (positive to positive, negative to negative). The controller will power on.
3. Connect Solar Panel: Connect the solar panel to the controller's solar terminals. Ensure correct polarity. The controller will begin charging the battery if sunlight is available.
4. Connect Load (Optional): Connect your DC load to the controller's load terminals. Ensure correct polarity. This output is controlled by the controller's load settings.

Note: Always connect the battery first and disconnect the solar panel first when disassembling the system.

6. Setup

After installation, configure the controller for your specific battery type to ensure optimal charging and battery longevity. The LCD display and buttons allow for easy setup.

6.1 Battery Type Selection

The Wanderer controller supports multiple battery types. To select the correct battery type:

1. Press the "SELECT" button to cycle through the display screens until you see the battery type setting (e.g., "SEL" for Sealed, "GEL" for Gel, "FLO" for Flooded, "LI" for Lithium).
2. Once the desired battery type is displayed, press and hold the "ENTER" button for 5 seconds until the setting flashes.
3. Use the "SELECT" button to change the battery type.
4. Press "ENTER" again to confirm your selection. The display will stop flashing, indicating the setting is saved.

For Lithium batteries, you may need to manually set charging parameters. Refer to the detailed user manual (PDF) for advanced settings.
