Our take on the EcoFlow 400W Rigid Solar Panel

The EcoFlow 400W Rigid Solar Panel is a folding monocrystalline panel built for camping, RV trips and home backup. Its ETFE-coated cells reach up to 22.4% efficiency, and the fiberglass and EVA build carries an IP67 waterproof rating. The protective case unfolds into a kickstand that adjusts from 40 to 90 degrees, and a built-in shoulder strap lets one person carry the 27.5 lb panel. It pairs with EcoFlow power stations through MPPT charging. Against lighter folding panels it trades weight for higher output per panel; against fixed roof panels it folds and moves.

Questions and answers

How much power does it actually produce?
It is rated at 400W with up to 22.4% conversion efficiency. Real output depends on sun angle, shade and temperature, so expect less than the rating in most conditions.
Is it waterproof?
Yes, it carries an IP67 rating, so rain and splashes are not a concern. The connectors and power station still need to stay dry.
Can I carry it alone?
Yes. It weighs 27.5 lbs and has a built-in shoulder strap for solo transport. The folding case protects it in transit.
Does it work with non-EcoFlow power stations?
It can feed other solar inputs that accept its voltage and connector, but MPPT charging is tuned for EcoFlow power stations. Check your station's solar input limits first.
How do I angle it toward the sun?
The case unfolds into a kickstand that adjusts from 40 to 90 degrees. That covers low morning sun through a near-vertical setting.
What is in the box?
The panel, its folding protective case with kickstand and shoulder strap, and the charging cable. Check the listing for the exact connector included.
