EF ECOFLOW 125W Bifacial Modular Solar Panel (4-Pack) Instruction Manual

4.1 High Efficiency Solar Cells

The panels utilize N-Type TOPCon solar cell technology, offering up to 25% conversion efficiency. The dual-sided design captures additional solar energy from reflected light, potentially generating up to 138W output per panel under optimal conditions. These cells perform well in overcast conditions and maintain high energy conversion at elevated temperatures, with a projected lifespan of up to 30 years with 90% output.

4.2 モジュール設計

The innovative modular design allows for flexible power configurations. Panels can be connected in parallel using XT60W connectors, supporting up to 8 panels (1000W total) or more complex series/parallel setups for higher wattage systems. This design facilitates seamless expansion within safe operating ranges.

4.3 Adjustable Support and Solar Angle Guide

Each panel includes an integrated adjustable support system, allowing for angle adjustments between 30-60 degrees to optimize solar generation. A built-in solar angle guide assists in positioning the panel at the ideal 90-degree angle to the sun for maximum energy capture.

4.4 Durable, All-Weather Design

Constructed with a robust anti-corrosive aluminum frame, 1 mm ultra-thin tempered glass, POE films for UV and moisture resistance, and PET backsheets, these panels are designed for long-lasting outdoor performance. They feature an IP68 waterproof rating and a waterproof XT60-W connector, ensuring reliability in various weather conditions.

4.5 Flexible & Lightweight

Each 125W solar panel weighs approximately 9.26 lb (4.2 kg), making the 4-panel set (37 lb / 16.78 kg) significantly lighter than many rigid panels of comparable total wattage. The lightweight and modular nature enhance portability and ease of setup, especially for mobile applications.

4.6 Plug and Play Connectivity

The panels are designed for easy integration with various power systems. They include photovoltaic connectors (MC4 compatible) and XT60 connectors, featuring waterproof, touch-safe, and anti-leak technology for reliable performance with EcoFlow power stations and third-party solar systems.

5.1 開梱と検査

1. Carefully remove the solar panels and accessories from their packaging.
2. Inspect each panel for any signs of damage during transit. If damage is found, contact customer support immediately.
3. リストされているパッケージの内容がすべて揃っていることを確認します。

5.2 Panel Deployment

1. Choose a location with maximum direct sunlight exposure, free from shadows.
2. Unfold the integrated adjustable support legs on the back of each solar panel.
3. Adjust the angle of the support legs to position the panel between 30-60 degrees relative to the ground.
4. Use the integrated solar angle guide to fine-tune the panel's orientation, aiming for a 90-degree angle to the sun's rays for optimal performance.
5. For outdoor use, especially in windy conditions, place weights (e.g., sandbags) on the support legs or secure the panels to prevent them from being moved or damaged by wind.

5.3 Interconnecting Panels

The 125W solar panels are designed for parallel connection using their XT60W connectors. For connecting multiple panels:

1. Connect the XT60W output of one panel to the XT60W input of another panel using the provided XT60W to XT60i Extension Charging Cable.
2. Repeat this process for all panels you wish to connect in parallel.
3. To connect the solar array to a power station or system, use the appropriate adapter cable (e.g., XT60W to Solar Connector Extension Cable for MC4 compatible systems, or Solar Connector to XT60i Extension Cable).
4. Ensure all connections are firm and secure to prevent power loss or damage.

6.1 発電所への接続

1. Once the solar panels are deployed and interconnected, connect the final output cable from the solar array to the solar input port of your compatible power station (e.g., EcoFlow DELTA or RIVER series).
2. Ensure the power station is turned on and ready to receive solar input.
3. The power station's display should indicate that it is receiving solar power and charging.

6.2 Monitoring Power Output

Regularly check the power station's display or companion app (if available) to monitor the real-time power input from the solar panels. This helps in verifying optimal panel positioning and performance.

6.3 日常使用のヒント

• 角度調整: Re-adjust the panel angle throughout the day to follow the sun's path for maximum energy capture.
• Shadow Avoidance: Ensure no shadows fall on the panels, as even partial shading can significantly reduce efficiency.
• Surface Reflection: Placing panels over reflective surfaces (e.g., light-colored ground, snow) can enhance the bifacial gain.

7.1 クリーニング

• Regularly clean the surface of the solar panels to remove dust, dirt, leaves, or other debris that may obstruct sunlight.
• 柔らかい布と、水で薄めた低刺激性の洗浄液を使用してください。刺激の強い化学薬品は使用しないでください。
• Clean when the panels are cool, typically in the morning or late afternoon, to prevent thermal shock or rapid drying of cleaning agents.

7.2 検査

• Periodically inspect the panels for any physical damage, such as cracks in the glass, bent frames, or damaged cables/connectors.
• Check all cable connections for tightness and signs of wear or corrosion.

7.3 ストレージ

• When not in use, fold the panels and store them in their protective bag.
• 直射日光や極端な温度を避け、涼しく乾燥した場所に保管してください。
• Ensure panels are clean and dry before storing.
