Industry-First 2kWh Solar Battery with Max 3000W Output

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.
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]

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.

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.

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]

Remote charging control for added peace of mind.

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.

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.


Powers home essentials for up to 2 days [15] with 6kWh capacity—keeping your kitchen running, lights on, and devices connected. [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.

Supports a family of four through 3 days of everyday living [15] with 10kWh capacity——keeping food fresh, heat running, lights on, and entertainment devices charged. [17]
*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.

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.
