  • All the AC output you’ll need. - A single DELTA Pro unit packs a 3600W AC output, which can be expanded up to 4500W with X-Boost technology. Power 99.99% heavy-duty devices at home, outdoors, or at work. You can even pair two units together to achieve 7200W.
  • The world’s fastest charging portable power station. - MultiCharge delivers record-breaking speeds at 6500W. To reach 6500W, you can opt for these charging methods.
  • Fully charge in 1.8 hours. - EcoFlow’s X-Stream charging technology isn't just fast, it's safe too. The battery management system ensures safety and longevity while you fully charge DELTA Pro from a standard AC wall outlet in 1.8 hours*.
  • Charge up at thousands of EV stations worldwide. - For the first time ever with a portable power station, you can charge up at thousands of EV stations worldwide. This unique charging method gives you up to 3400W fast charging on the go.
  • Go renewable with 1600W solar charging. - EcoFlow's suite of solar products give you a cost-effective renewable energy source to stay powered. You can use solar energy to charge DELTA Pro in just 2.8-5.6 hours. DELTA Pro has a wide voltage range from 11-150V, which makes it compatible with 90% of third-party solar panels with Solar connectors. And when the weather gets unpredictable, the smart maximum power point tracking (MPPT) automatically adjusts, maximizing your solar generation at any time of the day.
  • Get emergency backup power with the EcoFlow Smart Generator. - The EcoFlow Smart Generator serves as an emergency option that integrates with your DELTA Pro ecosystem. It auto-starts when your DELTA Pro hits a low level of charge, re-charges your DELTA Pro, and stops the engine all by itself once your DELTA Pro hits a full charge. Compared to a traditional gas generator, the EcoFlow Smart Generator delivers less energy loss, faster charging and higher efficiency. 
  • A battery that lasts for years on end. - DELTA Pro sports a brand-new LFP battery with 6500 cycles, which means you can use DELTA Pro for years and years before your unit reaches 50% of the original capacity. EcoFlow’s battery management system provides real-time analysis and regulation of voltage, current, and temperature. This unique protection mechanism makes DELTA Pro an incredibly safe and efficient home battery.
  • Multiple ways to control & monitor. - Control DELTA Pro either on the unit itself, using the remote control accessory, or unlock a ton of customization via the EcoFlow app. On the app, you can access your power settings, such as charging and discharging levels, AC charge speeds, control the Smart Generator and a whole lot more.
  • The world’s first portable home battery ecosystem. - DELTA Pro's expandable ecosystem provides you with power during blackouts, customizable energy around the clock, and lower energy bills. How does it achieve all this? With a selection of extra batteries, smart generators, solar trackers, wind turbines, a smart home panel, and more. From backup power to reducing your reliance on the grid with green alternatives, the DELTA Pro ecosystem can be customized to your needs.
  • Introducing the EcoFlow Smart Home Panel. - The new EcoFlow Smart Home Panel is the heart of the DELTA Pro home battery ecosystem. It integrates up to two DELTA Pro units with 10 home circuits. Each DELTA Pro can be connected with extra batteries, solar panels, or smart generators, giving you uninterrupted power during blackouts, smart energy management for your critical loads, and lower energy bills. 
  • Uninterrupted home backup. - With a fast 20ms switchover time, DELTA Pro and the Smart Home Panel can keep you powered on during a blackout. All the while, the EcoFlow app keeps you in the know, letting you select and modify your device priorities.
  • Smart Energy Management. - The EcoFlow DELTA Pro ecosystem stores energy day and night, reducing your reliance on the grid and lowering your energy bills by combating time-of-use rates. It integrates directly with your home using the EcoFlow Smart Home Panel. The EcoFlow app gives you a smart breakdown of your energy habits, and you can customize your energy usage for any type of situation.

FAQs — EcoFlow DELTA Pro + 400W Portable Solar Panel - 3 Panels (DELTAPro-400W3-US)

Q: All the AC ports support 3600W (US) output?

Answer: For US version, you can only have max 3600W AC output on the 30A AC port.

Q: What’s the max input DELTA Pro can achieve?

Answer: When charging DELTA Pro and its extra battery together, you can reach 6500W max charging speeds by combining AC, solar and Smart Generator methods. For DELTA Pro single unit, you can recharge it at standard wall outlets (1800W max), at EV station (3400W max)/Smart Home Panel/240V outlets (3000W max).

Q: How many solar panels can I use at the same time?

Answer: 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.

Q: Can I run a 240V device on the 120V US version?

Answer: 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).

Q: How do I update the firmware?

Answer: 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.

Q: How do I recharge DELTA Pro at 200V–240V in a 100V–120V region?

Answer: The cable provided with your DELTA Pro won’t plug into higher-voltage outlets, and you’ll need a third party adapter/charging cable.

System works as described. Solid. Heavy (very). Panels are great quality. Heavy. Wish they had a better/easier way to angle the panels. Using the panel cover is a little wonky. The panels don't stay completely flat when you angle them because of the folding joints. Learned that 800 W of panels doesn't mean you will get that. Happy to get 680. Angle with sun is critical for optimum power generation but impossible to continuously achieve without the ridiculously expensive holder that automatically rotates and follows the sun. Still love the system.

So far so good! I ran a deep freeze and a water pump for a few days with just the solar panel for recharge. When there were no clouds, the input was more than the output. I plan on running my office with the Delta Pro and have installed a lockout and 30 amp plug on my breaker panel for emergencies. If a problem arises, I will post again. God Bless!

I purchase theDelta pro and 400 watt solar panel and have been very pleased with it. I then purchased another 400 watt solar panel and plan on buying the extra battery in the future. It’s great to have the ability to power anything I may need whether it be for a weekend getaway or an emergency. Don’t get caught without an Ecoflow.

I have only got to use it once to date because the wire to connect it to the Delta Pro was not in the unit when purchased. I may be able to rate it better if I was able to conduct the tests I originally had anticipated when purchased.

Works like we need it to. It will power a 1600 watt device for two hours and then slowly recharge at 400 watts from our 110v source. Now we can use our device without worrying about throwing a circuit breaker.
