High-quality LFP battery.

With high rated power and peak power, the product’s AC output port can power most household appliances. Before you use it, we recommend that you confirm the power of the appliances first and ensure the power sum of all loaded appliances is lower than the rated power.

The charging time is shown on the product’s LCD Screen, which can be used to estimate the charging time of most appliances with stable power usage.

When it’s charging, the remaining charging time will be shown on the LCD Screen Meanwhile, the charging indicator icon begins to rotate with the remaining battery percentage and the input power shown on the right of the circle.

Gently wipe it with a dry, soft, clean cloth or paper towel.

Before storing, please turn off the product first, and then store it in a dry and ventilated place at room temperature. Do not place it near water sources. For long-term storage, please discharge and recharge the product every three months to extend its battery life.

No.

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. 1. 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. 2. 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. 3. Sunlight Angle. 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. 4. 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.

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 320W–350W of power in the 400W panel. (Current light conditions are normally 800W–900W/m² (74.3W–83.6W/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 nominal values were normally observed in the midday sun during the winter.)

The operating temperature of the Solar Panel is -20°C–85°C (-4°F–185°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 must not be dropped, pierced, bent, or sat on. These actions may break the cell and render the panel unusable. Any such damage will not be covered by the free warranty

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 station 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.

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 cause the power of 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.

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.
