Delta Pro Power Station

Structure

If you’re somewhat familiar with portable power stations, the fact that it has wheels might come as a surprise, but a telescopic handle on the front gives it the maneuverability of a suitcase. The body is made from rigid ABS plastic that has been infused with metallic particles so it’s both lightweight and resistant to abrasion. Commonly used outlets like USB and wall outlets are on the front, technical ports are under the front corner panel, and input ports are on the back. Four powerful fans on the top keep the battery cool to maintain high cycle life and top performance.

Battery

We picked the LiFePO4 battery chemistry because this industry favorite has a long cycle life, long shelf life, and high stability. Since DELTA Pros will be used around the world in every scenario imaginable, we paired it with an all-star battery management system to handle atypical temperatures, voltages, and currents, while simultaneously preserving the battery’s cycle life.

X-Stream
EcoFlow's proprietary X-Stream technology delivers one of the fastest AC recharging rates on the market. Using a built-in smart inverter, DELTA Pro can recharge its full 3600 watt-hours in 2 hours and 40 minutes at 1800W.

X-Boost
When the combined wattage of everything drawing power from DELTA Pro exceeds 3600 watts, EcoFlow’s X-Boost technology lets the unit accommodate 4500 watts worth of devices. Some devices will run at a lower wattage during this period – toasters may take longer and power tools may be less powerful, and some devices may not work at all. X-Boost shouldn’t be seen as a way to get 4500W out of DELTA Pro, but rather as a safety net so that a temporary surge in usage doesn’t overload the inverter.

Near, Far, Wherever

DELTA Pro has physical buttons and switches for when it’s accessible, but the EcoFlow app lets you adjust, control, and monitor more. Connect at close range with Wi-Fi-based pairing or Bluetooth, or connect it to a home network to manage it from anywhere around the world.

LCD Screen

The oversized numbers and auto-brightness are designed for maximum readability at a distance, and the generous size of the display fits in key information for energy management.

  • Capacity as a percentage
  • Estimated runtime at your current usage (when discharging)
  • Time until fully recharged (when recharging)
  • Real-time input and output watts iIndicators about what’s plugged in, alerts, and connections

USB Ports

The USB ports on the front are for powering everyday devices in DC, which is more efficient than charging from the AC ports. The USB-C ports are at 100W and can charge newer laptops.

20A Outlet

Anything that plugs into your home’s wall outlet can be plugged into these four NEMA 5-20 outlets, even professional 20-amp devices. These outlets vary by region to match what is used in the home.

30A Outlet

Mid-sized RVs and trailers need a higher amperage than a regular wall outlet can provide, which means most all-in-one batteries can’t be used as a battery backup. With DELTA Pro, the cable on your RV that normally plugs into a campground’s shore power box plugs into its built-in NEMA TT-30 receptacle. (Not to be confused with the NEMA 10-30 receptacle used for dryers and welding machines)

Solar/Car Charging Input Port

Recharge DELTA Pro on a DC current through this XT60 cable. It supports 12V/24V charging from a car outlet for when you’re on the go and up to 1200W from solar input when you’re where you want to be. Charging from a car outlet for a few hours will provide a relatively small amount of power that is better suited to keeping your DELTA Pro topped off than for meeting your energy needs. Three 400W solar panels linked in a series can fill all of DELTA Pro’s 3600 watt-hour capacity in 4 to 8 hours with the right conditions. It might sound like a long time, but remember, 3600Wh is a whole lot of power.

X-Stream AC Charging Port

X-Stream is an EcoFlow technology capable of recharging 3600 watts hours of capacity in 2 hours and 42 minutes. That number can drop to below 2 hours when charging from solar and AC simultaneously.

AC Charge Speed Switch

The Speed Switch toggles between fast charging and the speed you set in the app (or 400W by default).

Overload Protection Switch

If you do manage to exceed the output DELTA can handle and “trip it’s breaker” so to speak, press this button before continuing.

Extra Battery Ports

These two ports connect with EcoFlow’s Extra Battery or Smart Generator. Read more about them in the EcoSystem section below.

Anderson Port

Like the 30A AC outlet, the Anderson output port is another way for RVs and trailers to get 30 amp service. Some swear by it for its versatility and efficiency, though it may require some know-how to set up if your outfit doesn’t have it integrated yet.

Car Outlet and DC 5521

Why is it that as the automotive industry is dropping 12V accessory outlets, portable power stations are picking them up? Car outlets are still a great way to get power from the battery without losing energy to DC to AC inversion – things with a car outlet are more efficient. The same goes for the two DC 5521 outlets for 5.5mm barrel plugs that appeal to a techier audience.

Remote Control Port

EcoFlow’s Remote Control shows DELTA Pro’s screen from a wired or wireless connection (see the Ecosystem section below for more info). Since the wired connection uses an Ethernet cable, it’s possible to run the cable for long distances and install Ethernet wall jack.

Standby Switch

DELTA Pro normally powers off after two hours of not being used, but when switched to standby mode, it can power on when something tries to draw power or remotely from the app or the Remote Control.

Infinity Port

We came up with this port because we needed something that was as smart as USB with the power of AC. Why? It lets DELTA Pro connect to another DELTA Pro or to the Smart Home Panel for home integration. It’s also how you can charge DELTA Pro from an EV charging station, just like you would an electric vehicle.

THE ECOSYSTEM

It’s hard to talk about DELTA Pro without looking at the ecosystem surrounding it. By ecosystem we mean all the add-ons that are compatible with a DELTA Pro so you can do more with it. Charge from an EV charging station, integrate DELTA Pro with your home circuitry, use a smart gas generator for worst-case scenarios, or connect a second DELTA Pro for the highest output available from a portable power station.

Smart Home Panel

Essentially a second breaker panel, the Smart Home Panel connects the battery capacity of one or two DELTA Pros to your home’s light fixtures and wall outlets. Decide which rooms get battery power either from the panel’s interface or from the EcoFlow app. The panel is how DELTA Pro can get used year-round both as an energy management solution.

Backup: Using the panel cuts out the need to bring your portable power station inside or run extension cords to different parts of the house. It also makes it possible to power things that don’t have plugs like lighting, alarm systems, well pumps, bathroom vent fans, and ceiling fans.

Energy management: The Smart Home Panel’s second potential benefit is for capturing cheaper energy when electricity prices are lower, and running your home on stored power when rates are higher*. You can set all this up on the EcoFlow app so the switch to battery backup happens seamlessly and automatically.

Double voltage: With one DELTA Pro connected to the Smart Home Panel, any 120V wall outlet in your home becomes battery powered. With two DELTA Pro units, the Smart Home Panel combines their voltage to power both your 120V and 240V wall outlets for things like dryers, ovens, water heaters, and even HVAC systems.

*Savings are dependent on an electricity plan where prices vary throughout the day and are not at fixed rates.

Double Voltage Hub

For insanely high wattage devices when you’re not at home, the Double Voltage Hub – like the Smart Home Panel – connects two DELTA Pro units to output 7200 watts. You probably don’t own anything that would draw that much, but multiple things used at once could. The hub is suited for both mobile workstations using heavy-duty power tools and off-grid living spaces with all the amenities. Power 240V devices through the NEMA 6-20 outlets and NEMA L14-30 outlet, whose twist-lock design makes it ideal for any situation where there’s risk of pulling the cord loose.

EV Station Charging Adapter

DELTA Pro is the first portable power station capable of recharging from an electric vehicle charging station. With an adapter in the Infinity port, DELTA Pro can recharge from 0–100% in less than 2 hours at any Level 2 EV charging station.

Remote Control

A screen that mirrors DELTA Pro’s at a bigger size makes it easier to manage energy usage when DELTA isn’t right in front of you. Connect by Bluetooth for convenience or Ethernet cable to cover longer distances and added certainty.

Extra Battery Unit

DELTA Pro’s Extra Battery has the same look and the same 3600Wh capacity, just without the ports. Two Extra Battery units can triple a DELTA Pro’s capacity, and this trio can connect to another DELTA Pro with two Extra Batteries using the Double Voltage Hub or the Smart Home Panel. That’s 21.6kWh of portable power!

Smart Generator

It may seem we’ve become the very thing we meant to destroy, but keep in mind that gas generators and portable power stations have their own strengths. The reality of portable power stations is that you can’t just pour in more capacity during emergencies, and some scenarios may exhaust your battery capacity faster than solar can recharge it. EcoFlow’s Smart Generator plugs into DELTA Pro’s extra battery port and automatically turns on when DELTA Pro’s battery drops below a certain level. The Smart Generator runs until DELTA Pro is charged up to a level you set in the app, and then powers off. That’s added confidence knowing DELTA Pro always has a fallback for the worst case scenario. If that day should ever come, the Smart Generator can charge DELTA Pro during the day, so you can sleep peacefully while DELTA Pro powers on through the night.

    Frequently Asked Questions

    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 ofpower?

    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 220W Bifacial Solar Panel generate undernormal 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, anduse 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 whichside is which, and show can I optimize power generating using the rear side ofthe 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 220WBifacial 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 togetherin 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 Panel 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.

    How do I get the most solar power?

    Increase the efficiency of your solar panel by facing it directly at the sun without any obstructions. Remember to be careful when handling your solar panel because damaged cells provide less power.

    Deos it charge if it's inside?

    Yes, if the only thing between it and the sun is transparent, but it won’t charge as well compared to being outside. You can compare the difference by looking at the input section of your power station’s LCD screen.
