How many solar panels can I use at the same time?
It depends on the combined voltage and current of the solar panels you choose. It's fine as long as the solar panels use MC4 connectors and their combined voltage and current are within 11-150 volts and under 15 amps.
Can I run a 240V device on the 120V US version?
You'll need to connect two DELTA Pro units to power 240V electronics. You can do this by: 1) the Double Voltage Hub and use the AC outlets on the hub, or 2) the Smart Home Panel and use your home's 240V outlets (you'll need to setup 240V wiring on the Smart Home Panel during installation).
How do I update the firmware?
First of all, make sure your DELTA Pro is connected to the EcoFlow App using Internet mode. Secondly, go to the Firmware section in the Setting of the DELTA Pro you're looking to upgrade. Check for the latest firmware and follow the steps to finish the upgrade.
How do I recharge DELTA Pro at 200V-240V in a 100V-120V region?
The cable provided with your DELTA Pro won’t plug into higher-voltage outlets, and you’ll need a third party adapter/charging cable.
Are portable solar panels effective?
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 three 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.
Where do you place portable solar panels?
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.
Which solar panels are best for camping?
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.
Does the 220W Bifacial Solar Panel generate a full 220W 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. 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. Power output is only marginally impacted by sunlight hitting the panel within 10° either side this 90° angle. 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.
How much power can the 220W Bifacial 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 160W–180W of power in the 220W 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.)
What should I know about the operating temperature, storage, and use of the 220W Bifacial Solar Panel?
The operating temperature of the Bifacial 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 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.
The 220W Bifacial Solar Panel has two sides. How can I tell which side is which, and how can I optimize power generation using the rear side of the panel?
The front side of the Bifacial Solar Panel has a junction box. This side of the panel generates power by being positioned perpendicular to the sun's rays. Since the rear side of the panel faces away from the sun, it does not generate electricity in the usual way. Generally speaking, the rear of the panel uses ambient light to increase the overall performance of the product by up to 5%-25%. This figure is higher if mirrors are used, or when ambient light levels are high. Using the product with the rear side of the panel facing the sun generates 80% of the power when compared to using the front side. Using the panel in this way does not have a negative effect on the product.
Can I use non-EcoFlow branded power stations with the 220W Bifacial 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 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.
Can I connect both 110W and 220W Bifacial Solar Panels together in series?
Yes, but this is not recommended. While the voltages 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 110W panel and the full performance potential of the 220W panel cannot be released, 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 220W Bifacial Solar Panels in parallel?
Yes, but this is not recommended. 220W solar panel have a maximum current rating of 12A. Though these panels can be connected in parallel, DELTA and RIVER series power stations only support a maximum current of 12A. Parallel connections increase power output by doubling the current, but connecting the panels in this way would result in a 1+1=1 scenario whereby the current is limited to 12A by the connected devices. We do not recommend connecting the panels in parallel, unless you use a different brand of power station with an input current of 20A or above.
Shipping was slow just got it today . ordered on the 3rd shipped the 6th received the 20th haven’t had time even start it yet since it didn’t com with oil if I new that I would have had some ready to put in it. But I will update you once I have used it .
Nothing but good customer service and competitive prices
I enjoyed working working with Bill the owner of Outbound Power. To make a long story short the customer service is outstanding and you can directly speak with the owner and he will call you back too. I did know much of this company, but after some online research I felt the risk of ordering an expensive item was worth it and they had a competitive price for EcoFlow Delta 2 Power Station that I was interested in. Bill answered all my questions and I ordered the item and it shipped quickly with a tracking number and Outbound Power also would send me updates of the progress of the item. Unfortunately for some bad weather in California my shipment was delayed a week, but this was not their fault and it arrived by FedEx with no damage. I will certainly make another purchase from Outbound again when the time comes.
Additional items to finish out my back up power, storage capacity and move up to 240 volt capability
I like the concern shown by you and your company. The following is great. Great was the price and discounts offered. This stuff (EcoFlow) is expensive and you are the best pricing and deals on the market that I was able to find. I did get my EcoFlow pro from harbor freight with a 25% off one item club member discount. That saved me a lot. My delta 2 and smart generator was a great deal from you with the added $100 off made it impossible to pass up. Thanks for the great pricing and purchase process.
