EcoFlow DELTA Pro Portable Power Station (3600 Wh) — a portable home battery from the EcoFlow brand with an initial capacity of 3600 Wh, scalable up to 25 kWh for long-term backup power. The device is designed for reliable power supply at home, in production, in a van, or during outdoor recreation. Product category: Power Independence > Portable Power Stations.

Key Features and Benefits

The DELTA Pro has a rated AC output of 3600W, which can be boosted to 4500W with X-Boost technology. By combining two devices via the Smart Home Panel, the total power reaches 7200W. The station supports six charging methods and fast MultiCharge technology with a maximum combined power of up to 6500W, significantly accelerating energy replenishment.

Fast Charging

Using the included cable and appropriate mains power, the DELTA Pro can fully charge in approximately 1.9 hours. The international version supports mains charging up to 2900W in 1.9 hours. The maximum total charging speed when combining DELTA Pro and an extra battery is up to 6500W. For a single unit, the figures are: from a standard AC outlet — up to 2900W, from an EV charging station — up to 3400W, via the Smart Home Panel — up to 3000W; a unique fast charging method up to 3400W is also supported for international markets.

Expandable Ecosystem

The DELTA Pro is not limited to a single unit: it can be connected to extra batteries, solar panels, smart generators, and the Smart Home Panel. The Smart Home Panel allows integrating up to two DELTA Pro units and managing up to 10 home circuits for automatic backup power to critical loads and optimizing electricity costs.

Solar Charging and Compatibility

Support for solar charging up to 1600W makes the DELTA Pro suitable for transitioning to renewable energy sources. A wide operating voltage range of 11-150V ensures compatibility with approximately 90% of third-party solar panels, and the built-in MPPT automatically optimizes energy harvesting.

• Stationary solar panels — series: up to four 400W panels
• Portable panels — 2 in series and two in parallel (requires an additional cable for parallel connection) of 400W each

Smart Generator and Autonomy

The EcoFlow Smart Generator (sold separately) automatically starts when the DELTA Pro's charge level is low and stops once fully charged, allowing for quick and efficient energy replenishment compared to traditional gasoline generators. This is a convenient emergency solution for long-term autonomous power.

Battery Reliability

The DELTA Pro is equipped with an LFP battery with a lifespan of up to 6500 cycles before capacity reduction to 50%. The integrated Battery Management System (BMS) monitors voltage, current, and temperature in real-time, ensuring safety and extending the device's lifespan.

Safety Recommendations for Charging

For fast and safe charging, use the included AC charging cable. The connection must be made directly to an AC outlet with an output current >15A; if the current is lower, reduce the charging speed using the AC charging speed switch. EcoFlow is not responsible for the consequences of using other cables or non-compliance with instructions.

Management and Monitoring

The DELTA Pro can be controlled directly on the device body, using a remote control, or via the EcoFlow app. The app allows setting charge and discharge levels, adjusting AC charging speed, managing the smart generator, monitoring energy consumption, and other tools for optimizing energy use.

Mobility and Professional Use

The DELTA Pro's body is equipped with wheels and a retractable suitcase-style handle for convenient transport. For use in vans and during travel, an Anderson 30A port and AC outlets are provided. The station is suitable for household and business tasks: DIY projects, professional field trips, mobile workshops, and other scenarios where a reliable power source is needed.

Frequently Asked Questions

What is the maximum input the DELTA Pro can achieve? When combining DELTA Pro with an extra battery, the maximum charging speed reaches 6500W, combining AC, solar, and smart generator methods. A single unit can charge from a standard outlet up to 2900W, from an EV station up to 3400W, and via the Smart Home Panel up to 3000W.

How many solar panels can be connected simultaneously? This depends on the combined voltage and current of the panels. Panels with a Solar Connector can be used provided their total voltage and current are within 11-150V and less than 15A.

How do I update the firmware? Ensure the DELTA Pro is connected to the internet via the EcoFlow app. In the app, go to the Firmware section in your device settings, check for updates, and follow the instructions to complete the update.
