Industry-First 2kWh Solar Battery with Max 3000W Output
A New Era of Power Performance
Next-level energy for next-level peace of mind.
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]
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, or medical devices—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.
Long-Lasting, Durable, Always Ready for Emergencies
Rugged exterior and intelligent BMS for unmatched 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.
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.
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]
A New Level of Fast
Remote charging control for added peace of mind.
Deeper Insights, Easier Control
Monitor your energy usage, savings, and solar generation—all with one intuitive dashboard. Easily track battery status, solar forecasts, real-time electricity rates, and financial savings.
Cut Costs, Not Comfort
Charge During Low-Cost Periods to Save BigDELTA 3 Max Plus intelligently optimizes energy usage to help lower your electricity bills while powering your home sustainably. Set automated tasks to charge during off-peak evening hours and discharge during the day.
Easily Scales Up—From Hours to Days
Compact, Portable, Lighter than Ever - Works Anywhere
Lightweight and easy to carry, DELTA 3 Max fits into any setting from home to the great outdoors. Weighing just 20.3 kg, it's 13% lighter [3] for effortless portability while still packing serious power.

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.
