1. Introduction
Thank you for choosing the EF ECOFLOW 125W Bifacial Rigid Modular Solar Panel. This manual provides essential information for the safe and efficient use of your solar panels. Please read it thoroughly before installation and operation, and retain it for future reference.
The EF ECOFLOW 125W solar panel features N-TYPE solar cell technology, offering a high conversion efficiency of up to 25%. Its dual-sided design maximizes solar energy capture, potentially generating up to 138W output. Designed for versatility, these panels are ideal for various applications, including home PV systems, camping, RVs, and portable power stations. The modular design allows for flexible expansion, and the integrated adjustable support ensures optimal solar exposure.
2. Safety Information
Always observe the following safety precautions to prevent injury or damage to the product:
- Handle solar panels with care. Avoid dropping or subjecting them to strong impacts.
- Do not attempt to disassemble, modify, or repair the solar panel. Unauthorized modifications can void the warranty and pose safety risks.
- Keep the solar panel dry and away from water during installation and operation, unless specifically designed for wet conditions (IP68 rated for water resistance).
- Ensure proper grounding for all electrical connections to prevent electrical shock.
- Avoid touching exposed electrical contacts or wires.
- For complex installations or grid-tied systems, consult a qualified electrician or solar professional.
- Do not place heavy objects on the solar panel.
- Keep children and pets away from the solar panel during operation.
3. Setup Instructions
3.1 Unpacking and Inspection
Carefully remove the solar panels from their packaging. Inspect each panel for any signs of physical damage. If any damage is found, contact customer support immediately.
3.2 Modular Connection
The EF ECOFLOW 125W solar panels feature a modular design for flexible power configuration. You can connect multiple panels to increase your power output.
- Parallel Connection: Connect up to 8 panels in parallel to achieve up to 1000W output. This configuration maintains the voltage while increasing the current.
- Series/Parallel Connection: For higher voltage and current, up to 12 panels can be arranged in a 4 parallel, 3 series setup to generate up to 1656W.
Ensure all connections are secure and properly insulated. Refer to the wiring diagrams provided with your specific power station or inverter for correct series and parallel configurations.

3.3 Adjustable Support and Angle Guide
Each panel includes an integrated adjustable support, allowing you to set the panel at an optimal angle between 30-60 degrees for maximum solar generation. The screw-in design ensures stability for long-term outdoor use.
Utilize the additional Solar Angle Guide to position the panel so that sunlight strikes its surface at a 90-degree angle. This concentrates the sun's rays and significantly improves efficiency.
3.4 Connecting to Your Power System
The solar panels are designed for plug-and-play compatibility with various power systems:
- Photovoltaic Connector (MC4 Compatible): Use the included MC4-compatible connector to easily integrate with third-party solar systems.
- XT60 Connectors: Safely charge EF ECOFLOW power stations and other portable power stations equipped with XT60 inputs. The XT60-W connector is waterproof, touch-safe, and features anti-leak technology for reliable performance.
Always ensure the polarity is correct when making connections to avoid damage to the solar panel or the connected device.
4. Operating Instructions
4.1 Optimal Placement
For maximum power generation, place the solar panels in an area with direct, unobstructed sunlight. Avoid shaded areas from trees, buildings, or other objects, as even partial shading can significantly reduce output.
4.2 Angle Adjustment
Regularly adjust the panel's angle using the integrated support and Solar Angle Guide to track the sun's position throughout the day and across seasons. The ideal angle allows sunlight to hit the panel surface perpendicularly.

4.3 Weather Considerations
While the panels are designed for all-weather use (IP68 rated), extreme weather conditions such as heavy snow, hail, or strong winds may affect performance or cause damage. Secure the panels properly during high winds. In snowy conditions, clear snow from the panel surface to allow light absorption.
5. Maintenance
Proper maintenance ensures the longevity and optimal performance of your solar panels.
5.1 Cleaning
Clean the surface of the solar panels regularly to remove dust, dirt, leaves, and other debris that can reduce efficiency. Use a soft cloth and mild, non-abrasive cleaning solution with water. Avoid harsh chemicals or abrasive materials that could scratch the tempered glass surface.
5.2 Inspection
Periodically inspect the panels for any signs of physical damage, such as cracks in the glass, frayed cables, or loose connections. Check the aluminum frame for corrosion. Ensure the adjustable support mechanism is functioning correctly and securely.

5.3 Storage
If storing the panels for an extended period, ensure they are clean and dry. Store them in a cool, dry place, protected from direct sunlight and physical damage. It is recommended to store them in their original packaging or a protective case.
6. Troubleshooting
If you encounter issues with your solar panels, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Low power output | Shading on the panel surface Incorrect panel angle Dirty panel surface Cloudy weather Damaged cells or wiring | Relocate panel to full sun; remove obstructions Adjust panel angle using the Solar Angle Guide Clean the panel surface Output will naturally be lower in cloudy conditions Inspect for visible damage; contact support if suspected |
| No power output | Loose or incorrect connections Damaged cables or connectors Inverter/power station issue | Check all MC4 and XT60 connections for tightness and correct polarity Inspect cables for cuts or breaks; replace if damaged Test the power station/inverter with another power source if possible |
| Panel appears fragile or cracked | Impact damage during transport or use | Handle with extreme care. While durable, tempered glass can crack under severe impact. If cracked, discontinue use and contact customer service for replacement options. |
If the problem persists after attempting these solutions, please contact EF ECOFLOW customer support.
