Please note that DELTA Pro and 400W Solar Panel may be shipped separately from different warehouses and may arrive at different time.

DELTA Pro will ship within 4 business days, which may be lower than 400W solar panel.

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 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.

Built to weather the storm.

Our 400W portable solar panel can carry on collecting energy even during a downpour. With a protective ETFE film and a high IP resistance level of 68, the solar cells can withstand environments from humid and wet to dry and dusty.

Take solar power on the go.

EcoFlow’s 400W solar panel is a camping or RV must-have. The compact design saves valuable space for your other travel essentials. When you’re ready to head off on your next adventure, simply collapse the panel down to store in your van or car.

FAQ

Q1: All the AC ports support 3600W (US) output?

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

Q2: What's the max input DELTA Pro can achieve?

A: 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).

Q3: How many solar panels can l use at the same time?

A: It depends on the combined voltage and current of the solar panels you choose. It's fine as long as the solar panels use connectors and their combined voltage and current are within 11-150 volts and under 15 amps.

Q4: Can I run a 240V device on the 120V US version?

A: 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).

Q5: How do I update the firmware?

A: 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.

Q6: How do l recharge DELTA Pro at 200V-240V in a 100V-120V region?

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

Q7: 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.

Q8: 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.

Q9: Which 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.
