5. Setup and Installation

Proper installation is crucial for the safe and efficient operation of your solar charging system.

1. Mounting: Choose a dry, well-ventilated location for mounting the controller. Ensure there is adequate airflow around the unit for heat dissipation. Use the provided mounting brackets and hardware to secure the controller to a stable surface.
2. Wiring Order: Follow the correct wiring sequence to prevent damage to the controller and other components.
   • Connect the battery to the charge controller first. Ensure correct polarity.
   • Connect the solar panels to the charge controller. Ensure correct polarity.
   • Connect the DC load (if applicable) to the charge controller. Ensure correct polarity.
3. Battery Type Selection: The controller automatically detects 12V or 24V system voltages for non-lithium batteries. For lithium batteries, you may need to manually adjust the battery voltage settings prior to charging. Refer to the detailed user manual for specific battery type configuration.
4. Remote Temperature Sensor: Connect the remote temperature sensor to the designated port on the controller and place the sensor near the battery. This allows the controller to accurately compensate charging voltage based on battery temperature, extending battery lifespan.

6. Operating Instructions

Once installed, the Renogy Rover 30A MPPT controller operates largely automatically. However, understanding its functions will help you optimize your system.

• LCD Display: The integrated LCD provides real-time information about your system's performance, including battery voltage, charging current, and any operational errors. Use the navigation buttons to cycle through different display screens and settings.
• Load Control: The controller can manage a connected DC load. You can program load on/off times using the timer function accessible via the LCD display.
• Lithium Activation: The controller features a lithium activation function. When enabled, it allows charging of deeply discharged lithium batteries. This setting can be toggled ON or OFF.
