How It Works
In order to increase the efficiency of the EcoFlow Solar Panel, use it in
direct sunlight, position it perpendicular to the sunlight, and make sure the
solar panels are unobstructed.| The carrying case also doubles up as a
kickstand, which enables you to position the solar power in a 45° to 90°
angle.| Set your solar panels at an angle when the sun is lower in the sky
(for instance, early morning or late afternoon), and lay them flat in the
hours around noon.

Speed Up Solar Charging
Wire solar panels in series (refer to the figure below)
- Snap the male connector of one solar panel into the female connector of the other respectively to wire the two to three solar panels in series.
- Wire the two connectors that are unwired in step 1 with the Solar Charging Cable respectively.
- Connect the XT60 connector on the Solar Charging Cable to the XT60 port on the portable power station to recharge the unit.
- The number of solar panels that can be connected varies by product; please refer to your product’s manual for specific setup information.

Things to Remember When Using Solar Panel
- As the efficiency of solar panels depends upon light intensity and the tilt angle used, the charging power of the panel may be affected by a number of factors such as weather conditions, seasonal changes and location. The installation and connection of this product should be carried out strictly in accordance with the instructions found in the User Manual.
- Only the main body of this product is waterproof. The junction box and connection points should not be immersed in water.
- This product must not come into contact with highly corrosive substances, or be immersed in corrosive liquids.
- To avoid damaging the product, do not use sharp objects on the surface of the panel, and do not knock or impact the product.
- Do not apply pressure to the panel or allow the panel to be dropped on any of its corners, sides or faces. Such actions may result in damage to the solar panel.
- The panel must not be knocked, exposed to heavy pressure, or bent during transport, rotation or installation. We recommend that the panel is kept in a vertical position when being moved or stored.
- When storing the panel, always ensure that the positive and negative terminals of the junction box are not exposed to sunlight.
- To avoid the risk of injury, this product and its junction box must only be opened or disassembled by qualified personnel.
- Unwanted solar panels must be disposed of in accordance with the local legal requirements.
Avoid
This Solar Panel contains glass inside. Behaviors above that damage the solar panel, will cause the glass inside the solar panel to crack and efficiency drop, or even unusable. The free warranty period does not cover damage resulting from improper use of the product.
FAQs
Does the 400W Solar Panel generate a full 400W of power?
In most cases, it is normal for a solar panel not to deliver its full nominal
power. Some of the reasons why this happens, as well as some suggestions for
getting closer to the nominal power figure, are given below.
- Light Intensity. The amount of light shining on the panel will result in fluctuations to the power output. You are more likely to achieve nominal power output figures closer to those obtained under test conditions when using the product on a clear day during the midday sun, than when using the product in the morning or later in the 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 figures for nominal power in hazy, cloudy or rainy conditions.
- Surface Temperature. The temperature of the solar panel surface will also affect the amount of power generated. The lower the surface temperature of the panel, the more power will be produced. For example, solar panels generate more power when used during the winter than during the summer, and this is completely normal. Solar panels generally reach temperatures close to 60°C (140°F) during summer. This reduces nominal power by 13%, despite the higher levels of light shining on the panel.
- Sunlight Angl e. In optimal light conditions, the sun’s rays should remain perpendicular to the surface of the panel for best performance. The difference of +/-10 degrees of 90 degrees of sunlight hitting the panels has little effect on the power.
- Panel Shading. The surface of the solar panel should not be shaded during use. Shading caused by shadows, foreign objects, and glass can all greatly reduce power output.
Performance Issues Caused by Malfunctioning Panels: If the panel still isn’t
generating power or its output remains far below expected nominal power
figures after addressing the issues above, there may be an issue with the
panel itself. Please contact Customer Support for assistance.
How much power can the 400W Solar Panel generate under normal conditions?
This depends first and foremost on weather conditions. Generally speaking, on
a clear day with no clouds in the sky, sunlight hitting the panel at a 90°
angle usually generates 320W350W of power in the 400W panel. (Current light
conditions are normally 800W900W/m² (74.3W83.6W/ft²) with a panel
temperature of 50°C (122°F) under test conditions. Nominal power ratings are
based on 1000W/m² (92.9W/ft²) in AM1.5 conditions with a panel temperature of
25°C (77°F) under test conditions. Power output figures close to nominal
values were normally observed in the midday sun during the winter.)
What should I know about the operating temperature, storage, and use of the
400W Solar Panel?
The operating temperature of the Solar Panel is -20°C85°C (-4°F185°F). The
panel should be folded into its original shape and stored in its Protective
Case (Kickstand), which provides sufficient protection for the product. To
extend the service life of the panel, ensure that the product is not exposed
to external forces/impacts when not in use. The solar panel itself is made of
glass and must not be dropped, pierced, bent, or sat on. These actions may
break the glass and render the panel unusable. Any such damage will not be
covered by the free warranty.
Can I use non-EcoFlow branded power stations with the 400W Solar Panel?
Yes, but only certain types. The power station used must be compatible with
MC4 standards in order to work properly. In addition, other brands of power
stations may not offer the same levels of compatibility as EcoFlow-branded
power stations, may have lower nominal power ratings, and may not offer the
same levels of performance.
Can I connect 400W Solar Panels with another size of solar panels in
series?
Yes, but this is not recommended. Even if the voltage of the two panels are
identical, the current ratings are not. This means that when the panels are
connected in series, the current will be limited to that of the lower solar
panel which causes the power of the 400W solar panel can’t be released
entirely, resulting in a 1+2<3 scenario. Please purchase panels of the same
size if you intend to connect multiple panels in series.
Can I connect 400W Solar Panels in parallel?
Yes, but this is not recommended. Though 400W solar panels can be connected in
parallel, due to its high output current, may exceed the input current
limitation of the power station. Parallel connections increase power output by
doubling the current, but connecting the panels in this way would result in a
1+1=1 scenario because the input current limitation would restrain the total
solor input. We do not recommend connecting the multiple 400W solar panels in
parallel unless you use a power station with high input current limitation.
