This guide provides essential information for operating your Epropulsion 100W Foldable Solar Panel. For optimal performance, ensure the panel is placed in direct sunlight and positioned at a 90-degree angle to the sun. Always verify the polarity when connecting the MC4 output terminals to your solar charger.
Product Overview
The Epropulsion 100W Foldable Solar Panel is designed to convert solar energy into electrical energy to power electronic devices. It features a compact, foldable design for easy transport and is constructed with environmentally friendly materials.

Setup and Operation
Follow these steps to begin using your solar panel:

- Unfold: After opening the package, unfold the solar panel completely and spread it out on a flat, stable surface.
- Positioning: Ensure the front side of the panel is facing direct sunlight. The panel performs best when the angle between the panel and the sunlight is 90 degrees.
- Connection: Connect the output connector to your solar charger. Ensure the positive and negative terminals are connected correctly and not reversed.
Important Safety and Usage Notices
- Temperature Limits: Do not use the product in high-temperature environments. The operating temperature must be lower than 60°C. The optimal working temperature is 25°C.
- Handling: Handle the panel with care. Do not squash, strike, or drop the unit.
- Safety: Keep the solar panel out of the reach of children.
- Polarity: Pay close attention to the positive and negative terminals; do not reverse them during connection.
Maintenance
To maintain efficiency, keep the surface of the solar panel clean. If dust accumulates due to long-term outdoor use, clean the surface gently to avoid any negative impact on the output power.
