Description

Portable & Lightweight

With an input of 400W, this is one of the most powerful foldable solar panels on the market. Weighing only 12.5 kg, the lightweight design and built-in shoulder strap makes it ideal for outdoor adventurers.

Self-supporting

The protective case conveniently turns into a stand that adjusts from 40-90° allowing the solar panels to capture the most rays.

Robust & Weatherproof

Made from layers of pliable EVA and durable fiberglass to combine the versatility of flexible solar panels with the strength of rigid ones. Each monocrystalline silicon cell is covered with ETFE film, protecting against debris, dirt, and water. With an IP67 waterproof rating, the portable solar panel works in all kinds of weather, perfect for both camping and rooftop use.

Wide-ranging Compatibility

Uses the universally recognized MC4 connector, making it compatible with all EcoFlow DELTA Series portable power stations and many other third-party generators.

Smart Solar Energy

The EcoFlow 400W solar panel has a conversion efficiency of 22.4%, and when paired with an EcoFlow portable solar generator, can extract the most power throughout the day. The solar generator adjusts its efficiency using the Maximum Power Point Tracking (MPPT) algorithm, to deliver a constant power supply.

FAQ

Frequently Asked Questions

Can I connect multiple panels together?

No — this model uses an XT60i connector and is designed for single panel use only. It does not support series connection like some previous EcoFlow panels.

What EcoFlow power stations is this compatible with?

This panel is compatible with most EcoFlow units that accept XT60i input, including models in the River, Delta, and Delta 3 series. If you're unsure, feel free to contact us and we’ll confirm compatibility.

Can I use this panel with non-EcoFlow systems?

This panel can be used with other systems if the correct adapter is used, however it is primarily designed for EcoFlow products. Always check voltage and connector compatibility before use.

How fast will it charge my power station?

Charging speed depends on sunlight conditions and your power station model. In full sun, a 160W panel can provide strong daytime charging, but output will vary with weather, angle, and time of day.

Is this panel waterproof?

Yes — it has an IP68 waterproof and dustproof rating, making it suitable for outdoor use in rain, dust, and harsh environments.

Does it work in cloudy or low light conditions?

Yes, but output will be reduced. The high-efficiency TOPCon cells help maintain better performance in low light compared to older panel technology.

What makes this different from the older 160W panel?

This model replaces the previous 160W bifacial panel and features updated cell technology, improved efficiency, and a simplified plug-and-play design using the XT60i connector.

Do I need any additional cables or accessories?

No — the panel includes an MC4 to XT60i charging cable, so it can be connected directly to compatible EcoFlow units out of the box.

Is this suitable for permanent installation?

This panel is designed primarily for portable use. While it can be used in semi-permanent setups, for fixed installations we recommend rigid solar panels for long-term durability and performance.
