2. Safety Information

Warning: This product may contain materials cautioned by California Proposition 65. Always handle with care and follow all local safety guidelines.

Always ensure proper ventilation around the charge controller during operation. Incorrect wiring can cause damage to the unit, battery, or solar panels, and may pose a safety risk. Always observe correct polarity when making connections.

3. Setup and Installation

The SCC11ARPM solar charge controller is designed for easy installation with its pre-wired cables. Follow these steps for proper setup:

Wiring Instructions:

1. Connect Battery First: Always connect the battery to the charge controller first. Connect the positive (+) battery lead, then the negative (-) battery lead.
2. Connect Solar Panel: Once the battery is connected, attach the solar panel leads to the charge controller.
3. Disconnecting: To disconnect, always disconnect the solar panel first, then the battery.

Important: Use caution when wiring your solar system. Live power is present. AIMS Power recommends using 10 AWG waterproof PV wire and good quality MC4 connectors. NOTE POLARITY.

The battery input cable includes MC4 connectors. If you need an extender cable, use MC4 connectors. If you do not need an extender, you can cut off the MC4 connectors on the battery output cable and add lugs for direct connection. Ensure all connections are tight and of good quality.

4. Operation

Once properly installed, the SCC11ARPM controller will automatically manage the charging process from your solar panel to your battery. The LED indicators provide visual feedback on the system's status.

Recommendations During Use:

• The controller generates heat during operation. Install the charge controller in an environment with good ventilation.
• Regularly check your connections. Ensure wires and MC4 connectors are in good condition and securely connected.
• The charge controller is waterproof (IP68). Ensure all wiring connections are also waterproof to maintain system integrity.
• It is important to fully charge the battery at least once a month. Failure to do so may cause permanent damage to the battery.
• When charging the battery, ensure the load on the battery is lower than the charge rate so the battery can achieve a full charge.
• Incorporating a voltage meter into your system is recommended for monitoring.
• If you extend the battery cable, do not reverse the polarity. Reversing polarity will void the warranty.

5. Status Indicators

The SCC11ARPM features two LED indicators to provide real-time status information:

6. Maintenance

To ensure optimal performance and longevity of your AIMS Power SCC11ARPM Solar Charge Controller, follow these maintenance guidelines:

• Regular Connection Checks: Periodically inspect all wiring connections (solar panel to controller, controller to battery) to ensure they are secure, free from corrosion, and properly insulated. Loose connections can lead to power loss or system malfunction.
• Battery Health: Ensure your battery is fully charged at least once a month. Consistent undercharging can reduce battery lifespan. Consider using a voltage meter to monitor battery voltage.
• Environmental Conditions: Although the controller is IP68 waterproof, ensure it is installed in a location with adequate ventilation to dissipate heat, especially during prolonged operation. Avoid exposing the controller to extreme physical stress or corrosive environments.
• Cleanliness: Keep the controller free from excessive dust or debris. A soft, dry cloth can be used for cleaning the exterior. Do not use harsh chemicals or abrasive cleaners.

7. Troubleshooting

Refer to the LED Status Indications table (Table 1) for initial troubleshooting. Common issues and their potential solutions are listed below:

• Solar Charge Indicator Off: This indicates no voltage from the solar panel. Check solar panel connections, ensure the panel is receiving sunlight, and verify the panel's output voltage.
• Battery Status Indicator Off: This means the battery is not connected. Verify the battery connections to the charge controller. Ensure correct polarity.
• Battery Status Indicator Quick Flashing: This indicates the battery is over-discharged. Disconnect any loads from the battery and allow the solar panel to charge the battery. If the issue persists, the battery may need to be replaced or serviced.
• No Charging (Solar Charge Indicator Steady On, Battery Status Indicator Steady On, but no Slow Flash): Ensure the solar panel input power (Watts) does not exceed the controller's maximum (190W). Check for any excessive loads on the battery that might be drawing more power than the solar panel can supply.
• System Not Functioning: Double-check all wiring for correct polarity and secure connections. Ensure the battery voltage is within the acceptable range for the controller (12V system).

If problems persist after following these steps, contact AIMS Power customer support for further assistance.
