4. Setup

The installation of a 20KW hybrid solar power system is complex and requires specialized knowledge. It is highly recommended to engage certified solar installers for the entire setup process to ensure safety, compliance with local regulations, and optimal system performance.

4.1 Site Selection

• Solar Panels: Choose a location with maximum sun exposure throughout the day, free from shading. Ensure the roof structure can support the weight of the panels.
• Inverter & Batteries: Install in a cool, dry, well-ventilated area, protected from direct sunlight, moisture, and extreme temperatures. Ensure sufficient clearance for air circulation and maintenance.

4.2 Mounting Solar Panels

Mount solar panels securely using appropriate racking systems. Ensure correct tilt and orientation for your geographical location to maximize energy harvest. Follow all manufacturer guidelines for panel mounting.

4.3 Wiring Diagram and Connections

All electrical connections must comply with national and local electrical codes. This includes connecting solar panels to the inverter, batteries to the inverter, and the inverter to your home's electrical panel and the grid (if applicable). Use appropriately sized cables and circuit breakers.

5.2 Power Modes

Your hybrid inverter supports various operating modes, such as self-consumption, time-of-use, and backup mode. These modes can typically be configured via the inverter's display or a dedicated monitoring application. Consult the inverter manual for configuration details.

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your solar power system. Always follow safety precautions before performing any maintenance.

6.1 Solar Panels

• Cleaning: Periodically clean solar panels to remove dust, dirt, leaves, or snow that can reduce efficiency. Use soft brushes and water; avoid abrasive materials.
• Inspection: Annually inspect panels for any physical damage, loose connections, or signs of corrosion.

6.2 Inverter

• Ventilation: Ensure the inverter's ventilation openings are clear and free from obstructions.
• Connections: Periodically check all wiring connections for tightness and signs of overheating.
• Firmware: Keep the inverter firmware updated as recommended by the manufacturer.

6.3 Batteries

• Visual Inspection: Check batteries for any physical damage, swelling, or corrosion on terminals.
• Temperature: Ensure batteries are operating within their specified temperature range.
• Monitoring: Regularly monitor battery state of charge and health via the inverter display or dedicated app.

7. Troubleshooting

This section provides basic troubleshooting steps for common issues. For complex problems, contact Dawnice customer support or a qualified technician.

7.1 No Power Output

• Check Breakers: Ensure all AC and DC circuit breakers are in the ON position.
• Inverter Status: Check the inverter's display for error codes or status indicators.
