Our take on the EcoFlow 400W Solar Panel

The EcoFlow 400W Solar Panel is a foldable, portable solar panel rated at 400W, making it one of the more powerful folding panels you can carry. It weighs about 16 kg and has a built-in shoulder strap, and it can stand up on its own without a separate frame. It suits campers, van dwellers and home-backup users who want to recharge a portable power station off-grid. Against smaller folding panels it delivers more input per panel, but it is heavier and bulkier to pack than 100W or 200W panels.

About the EcoFlow 400W Solar Panel

The EcoFlow 400W Solar Panel is a foldable portable solar panel with a 400W input. It weighs 16 kg and has a built-in shoulder strap for carrying. The protective case turns into a stand that adjusts from 40° to 90° to angle the panel toward the sun.

The panel is built from layers of pliable EVA and durable fiberglass, which combine the versatility of flexible solar panels with the strength of rigid ones. Each monocrystalline silicon cell is covered with ETFE film that protects against debris, dirt and water. The IP68 waterproof rating allows use in all kinds of weather, including camping and rooftop use.

It connects with a standard MC4 connector. This makes it compatible with all EcoFlow DELTA Series portable power stations and many third-party generators. When paired with an EcoFlow portable solar generator, the generator uses a Maximum Power Point Tracking (MPPT) algorithm to adjust its efficiency and deliver a constant power supply.

Questions and answers

How much power does it actually produce?
It is rated at 400W under standard test conditions. Real output is lower in clouds, shade or when the panel is not angled at the sun, as with any solar panel.
Can it charge any portable power station?
It works best with EcoFlow power stations that accept a high solar input. Other brands work if their solar input voltage and connector match the panel's output.
Does it need a stand?
No. The panel is self-supporting and can be set up on its own. You can still angle it toward the sun for better output.
How portable is it?
It folds and has a built-in shoulder strap, but at about 16 kg it is best carried short distances, such as from a car to a campsite.
Can I connect several panels together?
Yes, panels can be wired in series or parallel within the limits of your power station's solar input. Check the voltage and current limits before connecting more than one.

At Off Grid Distribution, for $45.00, 94% under what the other stores charge, as of our latest check.
