Introducing the EcoFlow 400W Solar Panel - Your Ticket to Portable Solar Power

Harness the power of the sun like never before with the EcoFlow 400W Solar Panel. Crafted with cutting-edge monocrystalline silicon cells boasting an astounding 22-23% conversion rate, this sleek solar panel is your gateway to clean, efficient energy production.

Unmatched Efficiency

The EcoFlow 400W Solar Panel is a beacon of energy efficiency, offering up to 400W of power in full sunlight, thanks to its impressive 22-23% conversion rate. When paired with an EcoFlow solar generator, its Maximum Power Point Tracking (MPPT) algorithm works tirelessly to ensure a steady, uninterrupted power supply.

Foldable and Lightweight

Designed with convenience in mind, this solar panel is a traveler's dream. Weighing a mere 16 kg and featuring a one-piece foldable design with an integrated shoulder strap, it's a breeze to transport and store. Whether you're embarking on an RV adventure, camping trip, or embracing off-grid living, this solar panel is your ideal companion.

Built to Last

Rugged yet flexible, this solar panel comes equipped with a protective case that prevents overbending during transportation and storage. Its construction blends pliable EVA with durable fiberglass, combining the versatility of flexible solar panels with the strength of rigid ones.

Weatherproof Warrior

With an impressive IP68 waterproof rating and a protective ETFE film, this solar panel can brave the harshest weather conditions. It's equally at home in humid, wet environments as it is in dry, dusty ones. Even during heavy downpours, it continues to collect energy, ensuring you're never left in the dark.

Adjustable Stand for Maximum Sunlight

Say goodbye to complicated setups. The integrated protective case effortlessly transforms into a sturdy supporting stand, allowing you to adjust the solar panel's angle from 40-80°. Wherever you choose to set up, you'll capture the maximum amount of sunlight possible.

Universal Compatibility

The EcoFlow 400W Solar Panel features an MC4 connector, ensuring compatibility not only with EcoFlow DELTA Series portable power stations but also with many third-party generators. Versatile and user-friendly, it's a solar solution for everyone.
