4. Installation and Connections

Proper installation is crucial for the safe and efficient operation of your SmartSolar MPPT controller. Refer to the detailed wiring diagram below for connection points.

Mounting:

Mount the controller vertically on a non-flammable surface, ensuring sufficient clearance for ventilation. Avoid direct sunlight exposure to prevent overheating.

Wiring Sequence:

1. Connect the battery to the BATT terminals. Ensure correct polarity.
2. Connect the solar panels to the PV terminals. Ensure correct polarity.
3. Connect DC loads to the LOAD terminals (optional). Ensure correct polarity.

Always connect the battery first and disconnect the solar panels first when disassembling.

5. Operating Instructions

The SmartSolar MPPT controller operates automatically once correctly installed. For monitoring and advanced configuration, use the VictronConnect app.

Bluetooth Connectivity and VictronConnect App:

The integrated Bluetooth module allows wireless connection to your smartphone or tablet via the VictronConnect app. This app provides access to real-time data, historical performance, and settings.

1. Download the VictronConnect app from your device's app store.
2. Ensure Bluetooth is enabled on your smartphone/tablet.
3. Open the VictronConnect app and select your SmartSolar MPPT device from the list.
4. If prompted, enter the default PIN (usually 000000).

Through the app, you can:

• Monitor battery voltage, solar power, charge current, and load status.
• View 30-day historical data.
• Configure battery presets (e.g., Lithium, Lead-acid, AGM, Gel, Flooded).
• Adjust charge settings and set alarms.
• Update firmware.

Charging Modes:

The controller automatically manages the charging process through several stages to optimize battery health and lifespan:

• Bulk: Maximum current is delivered to rapidly charge the battery.
• Absorption: Voltage is held constant to fully charge the battery and balance cells.
• Float: Voltage is reduced to a lower level to maintain the battery at full charge.
• Storage: A slightly lower float voltage to minimize gassing and corrosion for batteries in storage.

6. Maintenance

The SmartSolar MPPT controller is designed for minimal maintenance. Regular checks can help ensure optimal performance and longevity.

• Visual Inspection: Periodically inspect the unit for any signs of damage, loose connections, or corrosion.
• Cleanliness: Keep the unit clean and free from dust and debris. Use a dry cloth for cleaning. Do not use solvents or abrasive cleaners.
• Ventilation: Ensure that the cooling fins are not obstructed to allow for proper heat dissipation.
• Firmware Updates: Regularly check for and install firmware updates via the VictronConnect app to benefit from improvements and new features.

7. Troubleshooting

If you encounter issues with your SmartSolar MPPT controller, refer to the following common troubleshooting steps:

• No Power/No Display: Check all wiring connections, especially the battery connection and fuse. Ensure the battery voltage is within the operating range.
• Low Solar Output: Verify solar panel connections and ensure panels are clean and not shaded. Check for proper panel voltage using the VictronConnect app.
• Battery Not Charging: Confirm battery type settings in the VictronConnect app match your battery. Check battery health and connections.
• Bluetooth Connection Issues: Ensure the controller is powered on and within range. Restart the VictronConnect app and your device's Bluetooth.
• Overheating: Ensure adequate ventilation around the unit. Reduce load if necessary.
