The EcoFlow 400W Rigid Solar Panel is the perfect solution for on-grid & off-grid power. Its high wattage means it can be used for storing energy during power outages, reducing your energy bill during this cost of living crisis and just generally powering an on-grid or off-grid house 24/7.

Your solar panel uses mono-crystalline silicon cells with a high conversion efficiency rate of up to 23%, meaning your electronics & batteries will charge faster than similar-sized 400W solar panels.

Designed with pre-cut hole and mounting feet make fast & easy installation to the roof of your house, garden room or camper van. (The solar system should be installed, adjusted, and repaired by professional, qualified electrical maintenance personnel who are familiar with the installation structure and operation of solar panel installations.)

This solar panel can also be used to recharge EcoFlow Power Kit Batteries or EcoFlow portable power stations by using the MC4 output on the solar panel. Solar panels can be connected in series or parallel to generate extra charging capacity. The all-inclusive connector means your solar panel will work with other 3rd party solar systems and power stations.

 

Rigid Solar Panel Mounting Feet

These feet are recommended if the solar panels are due to be installed on a roof. You will need 1x mounting feet kit for 1x Rigid Solar Panel.

  • Compatible with EcoFlow 100W and 400W Rigid Solar Panels.
  • An all-black design offers a low-key installation that blends in well with your roof
  • Lightweight and robust, crafted from anti-corrosive, waterproof aluminium alloy, suitable for long-term installation and use.
  • Package includes 4 × M6 hexagon screws, 4 × M6 spring washers, 4 × M6 flat washers, 4 × M6 large flat washers, 4 × M6 flange nuts.

Recommended Tools (Not Provided):

  • Adjustable Wrench
  • Tape Measure
  • Safety Glasses
  • Work Gloves

 


  • Charge Faster: Coming with an excellent conversion rating of 23%, you can charge faster. If you combine it as part of your Power Kits setup or EcoFlow portable power station, the integrated MPPT algorithm optimises your solar input

  • Easily Connect Your Power Systems: This solar panel has an all-inclusive solar connector, so it can be readily connected with any other third-party solar systems you may already have. You can charge up 48V power systems and portable power stations with one or multiple panels. The 400W solar panel includes a 300mm charging cable that gives you plenty of space to mount multiple panels, maximizing solar input.

  • Off-grid & On-grid Solution: This high-wattage panel works for both on-grid and off-grid solar-powered setups, storing energy for outages, reducing power bills, or powering an off-grid home.

  • IP68* Waterproof Rating: The 400W rigid solar panel is designed for the outdoors. With an IP68* waterproof rating and a robust anti-corrosive aluminium frame, the panel can withstand a wind speed of up to 130mph^ and a significant snow load of up to 113lb* and continue to capture solar energy for years to come. *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.) ^Well-mounted solar panels can withstand a dynamic 2400pa wind pressure load (130mph wind speed) and a static 5400pa snow load (113lb per sq foot of snow).

FAQs

Yes. When used outdoors for a long time, solar panels are prone to accumulate dust and foreign objects on the surface, causing a certain degree of light occlusion and reducing the output of power generation. Frequent cleaning keeps the surface of the solar panel clean and free of obstructions, allowing for better solar panel power output.
Yes. Parallel connection can double the current and increase the power. You can refer to the requirements for solar controllers and energy storage devices to ensure that they support larger values of input current to better determine the number of parallel connected solar panels. Additionally, it is necessary to pay attention to select a wire with a suitable wire diameter for safe connection according to the change of the output current.
Yes, but it is not recommended. Different energy storage controllers have requirements and restrictions on the output of solar panels. When solar panels with different current values are used in series, they will be limited, resulting in the inability to release the output power and even the short-board effect of 1+1<2.
The solar panel is made of mono-crystalline silicon wafer. During installation and use, please do not drop it on the ground with force, or use tools to hit the surface. Do not step on or sit on the solar panel, so as not to cause the mono-crystalline silicon wafer to break and affect its use. Artificial damages will void the warranty.
Please refer to the content in How to Choose the Installation Environment in this manual.
On a sunny day without clouds and direct sunlight, the power range of a 400W solar panel is between 320–350W (this data is obtained under the conditions of irradiance of 800–900W/m2 and the panel surface at 50°C (122°F)). The nominal data of the solar panel is obtained by testing under the conditions of AM1.5, meteorological conditions of 1000W/m2, and panel surface temperature of 25°C (77°F). A power close to the nominal value can usually be reached at midday on a sunny day in winter.
It is normal that the actual power does not reach the nominal power. You can get close to the nominal power by correcting for the following factors:
  1. Light Intensity: Changes in the intensity of sunlight will cause the output power to fluctuate up and down. The actual power will be closer to the nominal power when used at noon on a sunny day, and will be less than the nominal value in the early morning or afternoon. Weather conditions will also affect the amount of sunlight that shines on the panel.For example, you are much less likely to achieve the nominal power in hazy, cloudy, or rainy conditions.
  2. Surface Temperature: The surface temperature of the solar panel affects the power performance of the solar panel. The lower the surface temperature, the better the power performance. For example, when using solar panels in winter, the power is usually higher than in summer. Solar panels generally reach temperatures close to 60°C (140°F) during summer. This reduces nominal power by 10–15%, despite the higher levels of light shining on the panel.
  3. Light Angle:When the solar panel and the light angle are perpendicular, better power performance can be obtained. However, under special installation conditions (such as the roof of an RV), the solar panel can only be used in a tiled manner, which makes it impossible to form a vertical angle with the sunlight, resulting in a power loss of about 5–15%.
  4. Light Occlusion: When using solar panels, try to ensure that the surface is not covered, including projection, foreign objects, glass, etc., which will cause a significant drop in power.
