5.1 Výběr místa

Choose a location that receives maximum direct sunlight throughout the day, free from shadows cast by trees, buildings, or other obstructions. Consider the angle and orientation for optimal solar exposure based on your geographical location and season.

5.2 Mounting the Solar Panel

The DOKIO 400W solar panel features pre-drilled holes for compatibility with standard mounting hardware. Common mounting options include:

• Z-brackets: Ideal for flat surfaces like RV roofs or small sheds.
• Kolejnice: For larger installations on roofs or ground mounts, providing structural support.
• Tilt Mounts: Allow adjustment of the panel angle for seasonal optimization.

Ensure the mounting structure is robust enough to support the panel's weight (approximately 52.9 pounds) and withstand local wind and snow loads (up to 2400Pa wind load and 5400Pa snow load).

5.3 Elektrické připojení

The panel comes with 3-meter MC4 leads for connection to a charge controller. Follow these general guidelines:

1. Connect to Charge Controller: Connect the MC4 connectors from the solar panel to the solar input terminals of your charge controller. Ensure correct polarity (positive to positive, negative to negative).
2. Připojení k baterii: Connect the charge controller's battery output terminals to your battery bank. Always connect the battery to the charge controller first, before connecting the solar panel.
3. Connect to Inverter (Optional): If using an inverter, connect it to the battery bank.

Wiring Configuration for 12V Systems:

For 12V battery systems, parallel wiring is preferred for smoother charging and better stability. Series wiring should only be used with charge controllers specifically designed for high input voltages.

Figure 5: Diagram illustrating parallel wiring for solar panels to increase current, connecting to an MPPT charge controller, 24V battery, and power inverter. Note: MPPT controller should accept at least 24V input and handle at least 30A input current.

Důležité:

• Always consult the manual of your charge controller and battery for specific wiring requirements.
• Ensure all connections are tight and weatherproof.
• The 3-meter MC4 leads reduce the need for additional extensions, minimizing potential connection issues.

6. Návod k obsluze

Once properly installed and connected, your DOKIO 400W Mono Solar Panel will begin generating electricity when exposed to sunlight.

• Výkon: The rated 400W is a laboratory rating (Standard Test Conditions - STC). Actual power output in real-world conditions will vary based on factors such as sunlight intensity, ambient temperature, shading, cable length and gauge, and the efficiency of your charge controller (MPPT controllers are recommended for optimal performance).
• Sledování: Use your charge controller's display or a separate monitoring device to track the panel's output and battery charging status.
• Stínování: Even partial shading can significantly reduce the panel's output. Position the panel to minimize shading throughout the day. The half-cut cell design helps mitigate the impact of partial shading compared to traditional full-cell panels.

7. Údržba

Regular maintenance ensures the long-term performance and efficiency of your solar panel.

• Čištění: Periodically clean the surface of the solar panel with a soft cloth and water to remove dust, dirt, leaves, and other debris that can reduce efficiency. Avoid abrasive cleaners or harsh chemicals.
• Inspekce: Regularly inspect the panel for any physical damage, such as cracks in the glass, bent frames, or loose connections. Check the MC4 connectors and cables for signs of wear or corrosion.
• Shading Check: Monitor the surrounding area for new obstructions (e.g., growing trees) that might cast shadows on the panel.
• Odklízení sněhu: In snowy conditions, gently remove snow from the panel surface to restore power generation. Avoid using sharp tools that could scratch the glass.
