400W Portable Solar Panels

Our 400W portable solar panel offers high solar output, conversion efficiency rating, and a convenient folding design so it’s ready to grab and go at any time.

High Solar Output
and a One-piece Folding Design

Charge faster, wherever you go.

A single portable solar panel with a unique folding design, our 400W portable solar panel combines powerful energy production with portability. To achieve a higher solar conversion efficiency of up to 23%, we use multi busbar monocrystalline cells, so you get even more energy to recharge your portable power station.

An Integrated, Self-supporting Stand

Optimize your energy.

EcoFlow’s 400W portable solar panel comes complete with a protective case that doubles as a sturdy supporting stand. Simply set up your panel anywhere and conveniently adjust its angle to get the most sun possible.

Balancing Portability With Protection

Ready for the outdoors.

Made from durable and flexible materials, the portable solar panel is perfect for off-grid living and travel. Its multi-layered design offers high impact resistance for the rugged outdoors, while its 27.5 lb light-weight means effortless carrying to a campsite. A rigid layer embedded in the carry case protects the panel from overbending when you carry or store it.

IP68 Waterproof Rating

Built to weather the storm.

Our 400W portable solar panel can carry on collecting energy even during a downpour. With a protective ETFE film and a high IP resistance level of 68, the solar cells can withstand environments from humid and wet to dry and dusty.

*Water and dust resistance were tested under controlled laboratory conditions with a rating of IP68 under IEC standard 60529 (maximum water depth of 1 meter for up to 72 hours.)

A Compact, Space-Saving Design

Take solar power on the go.

EcoFlow’s 400W portable solar panel is a camping or RV must-have. The compact design saves valuable space for your other travel essentials. When you’re ready to head off on your next adventure, simply collapse the panel down to store in your van or car.

High-Efficiency Solar Cells

Capture more rays.

Made using highly efficient monocrystalline silicon cells. And with an exceptional energy conversion rate of 22-23%, you get more energy with every cell.
Plus, when connected to an EcoFlow solar generator, the Maximum Power Point Tracking (MPPT) algorithm auto-adjusts, guaranteeing a constant and stable power supply.

It can only hold one solar panel.

Our Solar Tracker supports third-party solar panels that are up to 94.4 x 43.3 inches (2.4 x 1.1m) and 55.1 lbs (25kg).

1. Please note that portable solar panels must be placed outdoors. They cannot charge a power station if placed indoors without exposure to sunlight.
2. Check whether there is a connection issue and then try again.
3. Confirm whether the input voltage and amperage match the specification of the portable power station. Also, check whether the positive and negative terminals are connected in reverse.
4. Check the display for error prompts and resolve the issue accordingly.
5. Third-party cables longer than 3 meters should have a wiring harness with a diameter of 6.5 mm and a wire diameter of 4 mm², otherwise there will be no input power on the display screen.
6. If the portable solar panel still does not work properly after trying the above steps, connect the portable power station to a car outlet using the XT60 port. Contact after-sales for help and send a video of the steps you have carried out. 

Charging power is affected by the strength and angle of the light. To increase output power, choose a time of day when the sunlight is strongest (hours around noon), and keep the portable solar panel positioned 90° to the sun. Try not to use the portable solar panel on cloudy days or in shaded areas.

When storing the portable solar panels, be careful to fold the portable solar panels and then put them in the bag with the junction box and wiring harness facing upward.

Yes, if the solar panel (1) has the same solar connectors and (2) has an output amperage, voltage, and wattage that the EcoFlow portable power station can support.

They’re made from monocrystalline silicon which is more efficient than polycrystalline. New materials like EVA and ETFE protect against high temperatures, corrosion, sunlight, as well as damage, which ensures that they can be used outdoors for long periods. They have a waterproof rating of IP67 and are also resistant to dust and UV rays.

Yes, if they (1) can connect via the same solar connectors and (2) can support the amperage, voltage, and wattage that an EcoFlow solar panel outputs.

1. Get the most solar power by facing your panel perpendicular to the sun without obstructions like trees or glass in between.
2. Use the carrying case to set your portable solar panels at an angle when the sun is lower in the sky (early morning or late afternoon), and lay them flat in the hours around noon.
3. Portable solar panels are most effective when the sun is high in the sky. 

1. The portable solar panel’s output power is about 80% of the rated power in strong, vertical sunlight. For example, a 110W portable solar panel has an output power of around 90W.
2. In partially cloudy weather, approximately 20-30W.
3. 5-10W in cloudy weather.
4. Raining/evening: 0W

When the current input power of the portable solar panel is very low, charging with solar power is not recommended. The standby power consumption may be higher than the input power, causing the battery voltage to leak and damage the battery. 

It’s compatible with all EcoFlow portable power stations, and any other portable power station that can connect with solar cables.

The solar tracker connects to the portable power station with an solar cable as well, and can be connected in series or in parallel the same way solar panels are.

The Solar Tracker has been rated for IP54 water resistance.

The Solar Tracker draws power from the attached solar panel to charge its battery, which means it can still rotate even if the sunlight isn’t that great.
