EcoFlow 400W Portable Solar Panel

400W Solar Output | Up to 23% Conversion Efficiency | Monocrystalline Silicon Cells | IP68 Waterproof & Dustproof | One-Piece Folding Design | Integrated Adjustable Stand

The EcoFlow 400W Portable Solar Panel is a high-output, portable solar charging solution designed to deliver substantial renewable energy wherever you need it. With 400W of rated solar power and up to 23% solar conversion efficiency, it can rapidly recharge compatible EcoFlow portable power stations for camping, RV travel, emergency backup, off-grid living, and outdoor use. Its one-piece folding design, durable multi-layer construction, integrated protective case, and adjustable self-supporting stand make it easy to transport, position, and use.

Generate 400W of Solar Power

With a powerful 400W rated output, the EcoFlow Portable Solar Panel provides significantly more solar input than smaller portable panels.

Use it with a compatible EcoFlow portable power station to capture sunlight during the day and store that energy for later use. This makes it an excellent solution for maintaining power during camping trips, RV adventures, extended outages, and off-grid applications.

Up to 23% Solar Conversion Efficiency

The panel uses highly efficient monocrystalline silicon solar cells with conversion efficiency of up to 23%.

This high conversion rate helps maximize the amount of usable solar energy generated from available sunlight, allowing you to recharge compatible power stations more efficiently.

One-Piece Folding Design

Unlike bulky fixed solar installations, the EcoFlow 400W Solar Panel features a convenient one-piece folding design.

Simply unfold the panel when you're ready to generate power and collapse it when you're finished. This makes transportation and storage much easier for users who travel frequently or have limited storage space.

Integrated Adjustable Stand

The protective carrying case doubles as a self-supporting stand, allowing you to position the solar panel at a suitable angle toward the sun.

The stand can be adjusted from approximately 40° to 80°, helping you optimize the panel's orientation throughout the day for better solar exposure.

Durable Multi-Layer Construction

The EcoFlow 400W Portable Solar Panel is constructed from multiple durable materials designed to combine flexibility with strength.

Its layered construction helps protect the solar cells during transportation and outdoor use while maintaining a portable folding form.

IP68 Waterproof & Dustproof

Built for outdoor environments, the EcoFlow 400W Portable Solar Panel features an IP68 waterproof rating.

Its protective ETFE film and durable construction help shield the solar cells from dust, debris, and water exposure, making the panel suitable for outdoor adventures and changing weather conditions.

Recharge Your EcoFlow Power Station

Connect the 400W Solar Panel to a compatible EcoFlow portable power station to generate renewable electricity from sunlight.

The included Solar-to-XT60 charging cable makes it convenient to connect the panel to compatible EcoFlow equipment. The panel also uses an MC4-compatible solar connection, allowing compatibility with suitable third-party solar generators when the electrical specifications match.

Fast Solar Charging for Portable Power

The 400W output makes this panel particularly useful when faster solar replenishment is important.

EcoFlow lists example charging times of approximately 3–6 hours for a DELTA 2 with one 400W panel, depending on solar conditions and system configuration. Actual charging times vary according to sunlight, temperature, power-station capacity, and other conditions. 

Expand Solar Input with Multiple Panels

For compatible EcoFlow systems, multiple 400W panels can be connected to increase available solar input.

For example, EcoFlow states that up to three 400W portable solar panels can be used with a compatible DELTA Pro system for up to 1200W of solar input, subject to the power station's specifications.

Ideal for Camping and RV Travel

The EcoFlow 400W Portable Solar Panel is designed for users who need substantial solar generation while traveling.

Take it with you for:

• Camping
• RV trips
• Road trips
• Outdoor events
• Remote work
• Off-grid living
• Emergency preparedness
• Extended outdoor stays

Its folding design helps save valuable storage space in an RV, van, SUV, or vehicle.

Power Your Devices with Stored Solar Energy

When paired with a compatible portable power station, solar energy generated by the 400W panel can be stored and used to power a variety of devices.

Depending on the connected power station, you can run or recharge laptops, smartphones, lights, refrigerators, communication equipment, small appliances, and other compatible electronics.

Smart MPPT Solar Optimization

When connected to a compatible EcoFlow solar generator, the system's MPPT (Maximum Power Point Tracking) technology automatically adjusts solar input to optimize energy harvesting.

This helps maintain efficient and stable solar charging as sunlight conditions change throughout the day.

Perfect for Emergency Backup

The EcoFlow 400W Portable Solar Panel can provide an independent charging source during extended power outages.

Instead of relying solely on grid electricity, use available sunlight to replenish a compatible portable power station and maintain access to stored energy for essential devices and appliances.

Clean and Quiet Renewable Energy

Solar energy provides electricity without fuel, exhaust fumes, or engine noise.

The EcoFlow 400W panel lets you harness renewable energy from the sun, making it an excellent complement to a battery-based backup system and a practical alternative to fuel-powered generators for many portable applications.

Portable Power for Off-Grid Living

For cabins, remote work locations, RVs, campsites, and other off-grid environments, reliable solar generation can make a significant difference.

The 400W output provides a substantial amount of renewable charging capacity while the folding construction allows the system to be transported when required.

Easy to Position and Store

The integrated case-and-stand system eliminates the need for a separate support structure.

When you arrive at your destination, unfold the panel, position the integrated stand, adjust the angle toward the sun, and connect it to your compatible power station.

When it's time to leave, fold the panel back into its compact configuration and store it in your vehicle or equipment area.

Important Solar Charging Consideration

The 400W rating represents the panel's rated power under standardized test conditions. Actual output will vary depending on sunlight intensity, weather, temperature, panel angle, shading, and other environmental conditions.

For maximum performance, place the panel in direct sunlight and avoid shadows from trees, buildings, vehicles, or other objects.
