400W Solar Panel FAQ
Q) Are portable solar panels effective?
A) Portable solar panels are an extremely effective, clean, and renewable way to charge a portable power station. EcoFlow 400W portable solar panels have a larger wattage than typical solar panels and are more efficient due to their monocrystalline cells. Spring up to four 400W portable solar panels and use with a DELTA Pro portable power station for input of 1600W. Additionally, EcoFlow portable power stations use an MPPT algorithm that ensures a constant energy supply. Unlike static solar panels, portable solar panels are easily moved and adjusted depending on where the sun is in the sky.
Q)Where do you place portable solar panels?
A) Positioning portable solar panels at an angle between 30-45 degrees, facing the direction of the sun, is best. EcoFlow portable solar panels have a built-in stand that can be adjusted, depending on where the sun is in the sky.
Q) Which portable solar panels are best for camping?
A) Solar panels that are portable, foldable, and lightweight are the best kind for camping. Pair one with a portable power station and string up to 4 together for immediate power that is clean, green, and renewable.
Q) What should I do if my solar panel isn't charging my portable power station?
A) 1. Please note that solar panels must be placed outdoors. They cannot charge a power station if placed indoors without exposure to sunlight.
2. Check whether there is a connection issue and then try again.
3. Confirm whether the input voltage and amperage match the specification of the portable power station. Also, check whether the positive and negative terminals are connected in reverse.
4. Check the display for error prompts and resolve the issue accordingly.
5. Third-party cables longer than 3 meters should have a wiring harness with a diameter of 6.5 mm and a wire diameter of 4 mm², otherwise there will be no input power on the display screen.
6. If the solar panel still does not work properly after trying the above steps, connect the portable power station to a car outlet using the XT60 port. Contact after-sales for help and send a video of the steps you have carried out.
Q) Why does the solar panel have such a low output?
A) Charging power is affected by the strength and angle of the light. To increase output power, choose a time of day when the sunlight is strongest (hours around noon), and keep the solar panel positioned 90° to the sun. Try not to use the solar panel on cloudy days or in shaded areas.
Q) What do you need to pay attention to when storing solar panels?
A) When storing the solar panels, be careful to fold the solar panels and then put them in the bag with the junction box and wiring harness facing upward.
Q) What do I need to pay attention to when using solar panels?
A) 1. The operating temperature range of the solar panels is -20 to 85°C (-4 to 185°F). Handle them gently during use, and avoid dropping, puncturing, or bending them.
2. Do not use solar panels on cloudy or rainy days. It is not recommended to use solar panels when light levels are low, because the input power is very low.
Q) Do EcoFlow power stations work with third-party solar panels?
A) Yes, if the solar panel (1) has MC4 connectors and (2) has an output amperage, voltage, and wattage that the EcoFlow portable power station can support.
Q) Do EcoFlow solar panels work with third-party products?
A) Yes, if they (1) can connect via an MC4 connector and (2) can support the amperage, voltage, and wattage that an EcoFlow solar panel outputs.
Q) How should I use the solar panels?
A) 1. Get the most solar power by facing your panel perpendicular to the sun without obstructions like trees or glass in between.
2. Use the carrying case to set your solar panels at an angle when the sun is lower in the sky (early morning or late afternoon), and lay them flat in the hours around noon.
3. Solar panels are most effective when the sun is high in the sky.
Q) What are the solar panels made from? What is their waterproof rating?
A) They’re made from monocrystalline silicon which is more efficient than polycrystalline. New materials like EVA and ETFE protect against high temperatures, corrosion, sunlight, as well as damage, which ensures that they can be used outdoors for long periods. They have a waterproof rating of IP67 and are also resistant to dust and UV rays.
Q) EF 110W Solar Panels Output Power?
A) 1. The solar panel's output power is about 80% of the rated power in strong, vertical sunlight. For example, a 110W solar panel has an output power of around 90W.
2. In partially cloudy weather, approximately 20-30W.
3. 5-10W in cloudy weather.
4. Raining/evening: 0W
When the current input power of the solar panel is very low, charging with solar power is not recommended. The standby power consumption may be higher than the input power, causing the battery voltage to leak and damage the battery.
