Triplo W TW-SOLAR Installation Manual

The Triplo W TW-SOLAR is a high-efficiency solar panel system designed for residential and commercial applications, featuring monocrystalline silicon cells, robust aluminum frame, tempered glass surface, IP67-rated junction box, and compatibility with standard mounting systems. It includes connectors, grounding hardware, and comprehensive monitoring capabilities. Below are key sections for safety, components, installation planning, mounting, electrical connection, commissioning, maintenance, and troubleshooting.

System Components

Key components included in the TW-SOLAR package: Solar Panels, Mounting Rails & Brackets, MC4 Connectors, Grounding Lugs, Junction Boxes, Installation Manual.

Safety Precautions

Installation must be performed by qualified personnel in accordance with local electrical and building codes.

1. Electrical Safety: Panels generate DC voltage when exposed to light. Cover panels with opaque material during installation.
2. Structural Safety: Ensure roof or mounting structure can support panel weight and wind/snow loads.
3. Personal Safety: Use fall protection, wear insulated gloves, and safety glasses.
4. Weather Conditions: Do not install during rain, snow, or high winds.

WARNING! Risk of electric shock and fire. Disconnect all sources of power before working on system. Use appropriate PPE.

Site Assessment & Planning

Evaluate installation site for optimal performance and safety.

1. Sun Exposure: Ensure no shading between 9 AM and 3 PM for maximum yield.
2. Roof Inspection: Check integrity, material, and angle. Verify load capacity.
3. Orientation & Tilt: In Northern Hemisphere, orient panels true South. Optimal tilt equals latitude.
4. System Layout: Plan array layout, wiring routes, and inverter location.
5. Permits & Codes: Obtain necessary permits and review local regulations.

CAUTION! Consult a structural engineer if roof condition is uncertain.

Mounting System Installation

• Roof Mounting: Attach L-feet to rafters using lag bolts. Seal penetrations with flashing and roofing sealant.
• Rail Attachment: Secure rails to L-feet using provided bolts. Ensure rails are level and properly spaced.
• Ground Mounting: Use concrete footings or ground screws. Follow foundation design per engineering specifications.
• Spacing: Maintain minimum 10mm gap between panels for thermal expansion and drainage.

Panel Mounting Procedure

Lift and secure panels onto installed rails.

1. Position first panel at starting corner of array.
2. Place panel on rails and secure with end clamps at both ends.
3. Add subsequent panels, using mid clamps between panels.
4. Ensure all panels are aligned and clamps are tightened to specified torque (typically 15-20 Nm).
5. Do not step on panels or apply excessive pressure to glass surface.

Tip: Use a panel lift or multiple installers for safe handling.

Electrical Wiring & Connection

Connect panels in series or parallel as per system design.

1. Route cables from panels to combiner box/inverter along designated pathways.
2. Connect panels using MC4 connectors: male to female, ensuring positive (+) to negative (-) for series strings.
3. Ground each panel and rail system using grounding lugs and copper wire (min. 6 AWG).
4. Label all strings and connections clearly.
5. Test open-circuit voltage (Voc) and short-circuit current (Isc) of each string before connecting to inverter.

WARNING! Verify polarity before making final connections. Incorrect wiring can damage equipment.

System Commissioning

Final checks and activation of the solar array.

1. Visual Inspection: Verify all mechanical and electrical connections are secure and correct.
2. Insulation Resistance Test: Perform megger test per IEC 62446.
3. Performance Check: With inverter connected and grid permission, monitor initial power production.
4. Monitoring Setup: Activate online monitoring platform using system serial number.
5. Documentation: Complete commissioning checklist and provide to customer.

Monitoring & Maintenance

Regular maintenance ensures long-term performance.

Monitoring: Access real-time data via Triplo W Solar App or web portal. Check for alerts or underperformance.

Maintenance Tasks:

• Bi-annual visual inspection for dirt, debris, or physical damage.
• Clean glass surface with water and soft brush if soiling reduces output (avoid abrasive materials).
• Check tightness of clamps and connections annually.
• Inspect wiring and junction boxes for signs of wear or corrosion.

CAUTION! Do not clean panels when surface is hot or during peak sun hours to avoid thermal shock.

Technical Specifications

Warranty & Support

Triplo W warrants that the TW-SOLAR panels will meet specified power output for 25 years (linear degradation, not exceeding 0.5% per year) and are free from material defects for 12 years. This warranty is valid only if installed by a certified installer according to this manual. For support, visit www.triplow-solar.com/support or contact +1-800-555-SOLAR. Keep original purchase receipt and commissioning documents for warranty claims.

Troubleshooting

Reset: For inverter or monitoring issues, power cycle system (AC then DC).
