4. Setup and Installation
4.1 Mounting
Mount the controller vertically on a non-flammable surface, ensuring adequate airflow around the heatsink fins. Avoid direct sunlight exposure to prevent overheating. Leave sufficient space above and below the unit for cable connections and heat dissipation.
4.2 Wiring Connections
Follow the wiring sequence carefully to prevent damage to the unit or battery system:
- Battery Connection: Connect the battery cables to the 'BATTERY' terminals. Ensure correct polarity (positive to positive, negative to negative). Use appropriately sized cables and fuses.
- Solar Panel (PV) Connection: Connect the solar panel cables to the 'PV' terminals. Verify correct polarity. Do not exceed the maximum open circuit voltage of 150V.
- Load Connection (Optional): If your model includes a load output, connect your DC loads to the 'LOAD' terminals. This output is typically protected against over-discharge.
- VE.Direct Connection: For wired communication with other Victron devices or a computer, use a VE.Direct cable.
- VE.Can Connection: For advanced system integration and communication, connect VE.Can cables to the designated ports.
- Relay and Remote Terminals: These terminals can be used for external control or signaling, as configured via the VictronConnect app.

4.3 Initial Configuration (VictronConnect App)
The SmartSolar controller does not have a physical display. All monitoring and configuration are done wirelessly via Bluetooth using the VictronConnect app on your smartphone or tablet. Download the app from your device's app store. Once installed, open the app, connect to your controller via Bluetooth, and follow the on-screen prompts to set up battery type, charging parameters, and other system settings.

5. Operating Instructions
5.1 Power-Up Sequence
After all connections are securely made, connect the battery first, then the solar panels. The controller will perform a self-test and begin charging if solar power is available and the battery requires charge.
5.2 Monitoring and Control
Use the VictronConnect app to monitor the system's performance. The app displays real-time data such as solar power output, battery voltage, charging current, and charging stage. You can also adjust settings like battery charge parameters and enable optional features like solar priority charging.

5.3 Charging Stages
The SmartSolar controller employs an intelligent charging algorithm to ensure optimal battery health and longevity. The main stages are:
- Bulk: Maximum current is delivered to rapidly charge the battery.
- Absorption: When the battery reaches a set voltage, the controller maintains this voltage while reducing current to fully charge the battery.
- Float: Once the battery is fully charged, the voltage is reduced to a lower level to maintain the battery without overcharging.
6. Maintenance
The SmartSolar controller is designed for minimal maintenance. However, regular checks ensure optimal performance and safety:
- Visual Inspection: Periodically inspect the controller and all connections for any signs of damage, corrosion, or loose wiring.
- Cleaning: Keep the heatsink fins free of dust and debris to ensure efficient cooling. Use a dry, soft cloth for cleaning. Do not use liquids or abrasive cleaners.
- Firmware Updates: Regularly check for and install firmware updates via the VictronConnect app. Updates often include performance improvements and new features.
- Ventilation: Ensure the installation area remains well-ventilated and free from obstructions.
7. Troubleshooting
If you encounter issues with your SmartSolar controller, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No charging activity | No solar input, incorrect wiring, low battery voltage, controller fault. | Check solar panel connections and output. Verify battery connections and voltage. Ensure correct polarity. Check for error codes in VictronConnect. |
| Low power output | Shaded panels, dirty panels, undersized panels, high temperatures. | Clear panel shading/dirt. Ensure panel array matches system requirements. Improve ventilation around the controller. |
| Bluetooth connection issues | Out of range, app not updated, interference. | Move closer to the controller. Update VictronConnect app. Restart phone/tablet and controller. |
| Controller overheating | Insufficient ventilation, high ambient temperature, excessive load. | Ensure proper airflow around the heatsink. Reduce load if possible. Relocate controller to a cooler environment. |
For more detailed diagnostics, use the VictronConnect app to view system status and any active alarms or warnings. The app provides pro-active system safety alerts to help identify and resolve issues quickly.
