The EcoFlow 400W solar panel is a lightweight, portable, and foldable solar energy solution designed for outdoor use and emergency power applications. With a nominal power output of 400 watts (±5 watts), this solar panel utilizes N-type TOPCon monocrystalline silicon cell technology to achieve a conversion efficiency of 25%, ensuring reliable energy generation even in challenging conditions. Weighing approximately 10.2 kg, the panel features a compact folded size of 659 mm × 967 mm × 36 mm and expands to 2509 mm × 967 mm × 26 mm when fully deployed for optimal sunlight exposure.
Constructed from durable fiberglass material with flexible EVA layers and ETFE film coating, the panel combines the versatility of flexible solar technology with the strength of rigid panels. The protective cover transforms into an adjustable stand that can be positioned from 40 to 90 degrees, allowing users to optimize the panel's angle for maximum solar radiation capture throughout the day. Featuring an IP68 waterproof and dustproof rating, this solar panel operates effectively in various weather conditions, making it suitable for camping trips, rooftop installations, and emergency power scenarios.
The panel employs the universally recognized XT60 connector type and offers broad compatibility with EcoFlow DELTA series portable power stations as well as many third-party generators. Electrical specifications include an open-circuit voltage of 39.3 volts (Vpm 34.5 volts) and a short-circuit current of 12.2 amperes (Ipm 11.7 amperes). The integrated shoulder strap enhances portability, while the self-supporting design eliminates the need for additional mounting hardware in many applications. This solar energy solution is particularly valuable for outdoor enthusiasts, remote work locations, and backup power requirements where reliable electricity generation is essential.
