The EcoFlow 400W Foldable Solar Panel is one of the most powerful portable panels available, designed for those who need reliable, high-output energy wherever they go. Built with monocrystalline silicon solar cells featuring an impressive 22.6% efficiency rate, it converts sunlight into electricity more effectively than standard panels. With a maximum output of 400W, an open-circuit voltage (Voc) of 48V, and a maximum power current (Imp) of 9.8A, it’s capable of producing up to 2,000Wh of clean energy daily under optimal weather conditions. This makes it perfect for pairing with EcoFlow power stations, off-grid setups, RVs, or emergency backup systems. The panel unfolds to a surface area of 105.8 × 236.5 cm, made up of four connected 100W panels, yet folds neatly into a 105.8 × 62.0 cm case for easy storage. Weighing only 12.5 kg (19 kg with the protective cover and kickstand), it’s highly portable while still delivering professional-grade performance.
Designed for durability and outdoor use, the EcoFlow 400W Solar Panel is equipped with a rugged ETFE protective coating that shields the cells from dirt, dust, and moisture, making it IP68-rated waterproof and weatherproof. Its included carrying case doubles as a kickstand, allowing you to adjust the panel’s angle from 40° to 90° for maximum sun exposure throughout the day. The standard MC4 connectors make it universally compatible with EcoFlow stations and most other solar setups, ensuring flexibility for both home backup and mobile applications. Whether you’re powering your adventures, keeping your RV charged, or preparing for emergencies, this foldable solar panel provides a dependable and eco-friendly energy solution that’s built to last.
