- Warning Symbol [!] - Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.
- Caution Symbol [⚠️] - Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury.
Module Components and Handling
The Longi Hi-MO X10 module is designed for high performance and durability. Each module typically includes:
- Photovoltaic cells
- Protective glass
- Encapsulant layers
- Backsheet
- Junction box with bypass diodes
- DC output cables with connectors
Handling:
- Carry modules vertically.
- Avoid dropping or impact.
- Do not step on, walk on, or place heavy objects on the modules.
- Keep modules dry and protected from moisture.
- Store modules in a cool, dry place, away from direct sunlight and extreme temperatures.
Installation Procedures
This section outlines the general steps for installing Longi Hi-MO X10 modules. Specific details may vary based on the mounting system and site conditions.
1. Mounting Structure Installation
Install the mounting structure according to the manufacturer's instructions and local building codes. Ensure the structure is securely fastened and capable of supporting the weight of the modules and anticipated environmental loads (wind, snow).
2. Module Mounting
Attach the modules to the mounting structure using the specified clamps and hardware. Ensure the clamps are correctly positioned and tightened to the recommended torque. Torque Symbol [⚙️] - Refer to the mounting system manual for specific torque values.
Modules should be mounted in portrait orientation for optimal performance and structural integrity.
3. Electrical Connections (DC Side)
Connect the modules in series or parallel strings as per the system design. Ensure connectors are clean and dry before mating. Push connectors together firmly until they click into place. Connection Symbol [✔️] - A secure connection is indicated by an audible click.
Wiring Diagram Description: Imagine a series of solar panels connected end-to-end. The positive (+) terminal of one panel's cable connects to the negative (-) terminal of the next panel. This continues to form a string. Multiple strings may then be connected in parallel to an inverter.
4. Grounding
Proper grounding is critical for safety. Connect the grounding terminal on the back of each module to the grounding conductor of the system using the provided grounding hardware. Ensure the mounting structure is also properly grounded. Grounding Symbol [?] - Connect to the designated grounding point.
5. System Integration
Connect the DC output of the module strings to the DC input of the inverter. Ensure correct polarity. Connect the inverter to the AC grid according to the inverter manufacturer's instructions and local regulations.
6. System Testing
After installation, perform electrical tests to verify correct connections, voltage, and current. Check for any faults or errors. Test Symbol [▶️] - Initiate system test sequence.
Maintenance
Regular inspection and maintenance will ensure optimal performance and longevity of the photovoltaic system.
- Periodically clean the module surfaces, especially if they are covered by dust, dirt, or snow. Use water and a soft cloth or brush.
- Inspect modules and wiring for any signs of damage, corrosion, or loose connections.
- Check the mounting structure for stability.
Troubleshooting
If the system is not performing as expected, consult the following common issues:
- No power output: Check all DC and AC connections, ensure the inverter is operational, and verify that no circuit breakers are tripped.
- Reduced power output: Inspect modules for shading, dirt, or damage. Check string connections.
- Error codes on inverter: Refer to the inverter's manual for specific error code meanings and solutions.
