EcoFlow 400W Portable Solar Panel

The EcoFlow 400W Portable Solar Panel is a powerful and efficient solar solution designed for fast, reliable off-grid energy. Built with high-performance monocrystalline silicon cells, it delivers up to 400 watts of power with a conversion efficiency of around 22–23%, maximizing energy capture even in limited sunlight.

This one-piece folding panel comes with an integrated kickstand case that doubles as an adjustable stand, making it easy to set up and optimize the angle for maximum sun exposure. The panel is constructed with multi-layered durable materials, including a robust ETFE coating and a fiberglass backing, providing long-lasting protection and efficient performance in a variety of environments. Rated IP68 waterproof and dustproof, the EcoFlow 400W panel is engineered to withstand harsh outdoor conditions such as rain, dust, and high temperatures. Weighing approximately 16 kilograms for the panel alone (or 19 kilograms with the case), it remains portable and compact, folding neatly for storage or transport.

When connected to an EcoFlow power station, the panel supports MPPT (Maximum Power Point Tracking) for optimized energy transfer and efficient charging. For example, a single panel can charge a DELTA Mini in 3–6 hours, while using multiple panels can recharge a DELTA Pro in just 3.5–7 hours, making it ideal for home backup, camping, RVs, and off-grid living.
