Sunvivae 400W Bifacial Foldable Solar Panel with 7-in-1 Adapter Cable
Sunvivae 400W Bifacial Foldable Solar Panel with 7-in-1 Adapter Cable
400W Bifacial Power. Foldable Freedom.
Capture direct sunlight from the front and reflected light from the rear with a high-output portable panel built for compatible power stations, RV travel, camping and emergency backup.
Power from Both Sides
The front surface captures direct sunlight while the rear surface can use reflected light from bright ground surfaces. Actual rear-side gain varies with surface reflectivity, panel height, angle, shading, temperature and weather.
400W Rated Output
High-output solar collection for compatible portable power stations and off-grid systems.
Bifacial Collection
Rear-side cells can collect reflected sunlight from surfaces such as light-colored roofs, sand or snow.
Efficient Cells
16BB N-type monocrystalline cells deliver up to 23.5% cell conversion efficiency.
Durable Materials, Portable Form
An ETFE surface helps resist dust and outdoor wear, while the reinforced foldable body protects the panel during travel and storage. The solar panel is IP68-rated; keep plugs and connection points dry and never connect cables while wet.
Use it beside an RV, at camp or as part of a prepared home-backup setup—then fold it down for transport.
Three Reinforced Kickstands
Deploy the panel on a stable, level surface and adjust its angle to improve exposure as the sun moves. Secure the panel in windy conditions and do not leave it unattended in severe weather.
7-in-1 Adapter Cable Included
Standard solar connectors feed the included adapter cable, giving you several connection options for compatible power stations. Always verify input voltage, current limit, connector size and polarity before connecting.
Power-Station Ready
Designed for stations whose solar input supports the panel's voltage and power range.
Seven Connector Options
DC7909, DC8020, XT60, DC5521, DC5525, DC35135 and Anderson.
Battery Systems
A compatible solar charge controller is required when charging a standalone battery.
High Output, Foldable Storage
290 × 90 × 1.5 cm
68 × 88 × 7 cm
Frequently Asked Questions
Will it always produce 400W?
400W is the panel's rated power under standardized test conditions. Real-world output normally varies with sun, temperature, angle, shading, cable loss and the receiving device's input limit.
How much extra energy does the rear side produce?
There is no fixed percentage. Rear-side contribution depends heavily on how much light the ground reflects and how the panel is positioned. Bright surfaces and open spacing generally help more than dark surfaces.
Is it compatible with EcoFlow, Jackery, BLUETTI or Anker?
The included adapters support many common connector formats, but compatibility depends on the exact model's voltage, current, wattage, port and polarity requirements. Check the power station manual before connecting.
Can it charge a battery directly?
Do not connect it directly to a standalone battery. Use a correctly sized solar charge controller matched to the panel and battery chemistry.
Can it stay outside in rain?
The panel is IP68-rated, but connectors should be kept dry and properly protected. Avoid connection or disconnection in wet conditions, submersion, and prolonged exposure to severe weather.
