Always Ready. More Power.

Industry-First 2kWh Solar Battery with Max 3000W Output (DELTA 3 Max Plus)

25% More Power [3]: 3000W Output, 2kWh Capacity

A New Era of Power Performance

Next-level energy for next-level peace of mind.

3000W Output, 6000W Surge — Powerful. Stable. Built to Handle It All.

DELTA 3 Max Plus delivers 3000W AC rated output (6000W surge). With X-Boost™ 3.0 technology, it supports devices up to 3900W—effortlessly taking on your heavy-duty appliances. The inverter samples AC voltage and current every 33μs with high precision using a DSP chip, ensuring pure sine wave output with beyond grid-level stability—ideal for powering sensitive electronics reliably.

All Your Essentials. All at Once.

DELTA 3 Max Plus delivers a powerful 3000W output—enough to run your microwave, kettle, fridge, and blender all at once without a flicker. Lunchtime? Go full throttle. No unplugging, no interruptions—just seamless power. [4]

Pick Your Priority Outputs, Extend What Matters Most

Smart Remote Switching | Reduce waste to increase runtime for essentials

DELTA 3 Max Plus introduces Smart Output Priority Tech. This convenient new feature lets you choose which circuits stay powered via the app. Prioritize what matters—like your fridge, Wi-Fi—and extend runtime when it counts most, even when you're away.

Smart Power Reserve | Set your desired battery threshold (%) to automatically shed non-essential loads during outages

With app-based presets, DELTA 3 Max Plus automatically follows your priority settings during outages—shutting off lights while keeping your fridge running. Wake up to fresh food and plenty of power left—just like nothing happened.

Automotive-grade full-tab LFP cells

Long-Lasting, Durable, Always Ready for Emergencies

Rugged exterior and intelligent BMS for unmatched reliability

Automotive-grade Full-Tab LFP Cells: Next-Level Battery Reliability

DELTA 3 Max Plus is equipped with automotive-grade full-tab LFP cells. The full-tab design reduces resistance, enhances efficiency and safety, and provides higher capacity with less heat, resulting in a longer battery lifespan.

Unrivaled Balance for Unmatched Battery Longevity

With 27% fewer cells per kWh, [7] our 16-cell design runs cooler, lasts longer, and delivers greater stability. Each cell is rigorously tested for capacity, voltage, and internal resistance—resulting in a highly uniform pack that protects against overcharging, imbalance, and premature wear.

Built to Last

From battery chemistry to structural design, DELTA 3 Max Plus is engineered for extreme durability, environmental resilience, and whisper-quiet performance—delivering power you can count on for over 10 years. [2]

Comparison

1. 0-80% in 47 minutes was measured in optimal conditions using X-Stream AC charging.

2. Based on proper product usage, DELTA 3 Max Plus is estimated to have a lifespan of approximately 10 years, according to internal simulation test data. This information is for reference only; actual user experience may vary.

3. Compared with EcoFlow DELTA 2 Max.

4. The conclusion that multiple appliances can be powered simultaneously is based on internal testing. Actual performance may vary in real-world use.

5. Refers to the internal resistance of EF Full-Tab LFP Cells being 1.5mΩ, which is 25% lower than the 2mΩ internal resistance of the previous EF #C33 Battery Cell.

6. A 25% reduction in single-cell internal resistance. According to the heat generation formula Q = I²Rt, under the same current, a 25% reduction in resistance leads to a proportional 25% decrease in heat generation.

7. Compared with the previous usage of EF #C33 Battery Cell.

8. Unless otherwise noted, all above data comes from EcoFlow labs and is for reference only. The actual data may vary slightly depending on the usage environment, device condition, software version, and other factors.

9. Noise levels measured at 0.5m under 25°C ambient: ≤25dB (600W) for charging/discharging.

10. All charging speed data comes from EcoFlow labs and is for reference only. The actual data may vary slightly depending on the usage environment, device condition, software version, and other factors.

11. Feature requires preset activation via the EcoFlow App.

12. EcoFlow Alternator Charger Plus 1000 will be launched soon and is sold separately.

13. Compared with car cigarette port charging.

14. Certain features in the EcoFlow app will be available soon. Please refer to the EcoFlow app for details on feature availability.

15. Multiple appliances' backup time based on ideal conditions; actual results may vary.

16. Require connecting 1 × DELTA 3 Max Plus + 2 × DELTA 3 Max Plus Smart Extra Battery with EcoFlow Smart Extra Battery Expansion Adapter. The EcoFlow Extra Battery Expansion Adapter will be released soon.

17. Require connecting 1 × DELTA 3 Max Plus + 2 × DELTA Pro 3 Smart Extra Battery with EcoFlow Smart Extra Battery Expansion Adapter. The EcoFlow Extra Battery Expansion Adapter will be released soon.
