EcoFlow DELTA Pro 3 Portable Power Station | 4000W | 4096Wh

Cut Power Bills Through Self-Consumption

Build a home energy storage setup without grid-tied installation costs. Store solar energy in the DELTA Pro 3 during the day and use it at night to power household appliances, saving approximately 22% on daily energy consumption with one unit. Add an extra battery to save 44%, and two extra batteries to save up to 66% per day.

*Savings estimates are EcoFlow's published figures and assume sufficient daily solar generation to fully charge the DELTA Pro 3 (or DELTA Pro 3 with extra batteries) each day. Actual savings vary based on NZ solar conditions, your power usage, and your electricity provider's rates. A site-specific assessment is recommended for accurate estimates.

Keep Your Home Running Smoothly

One DELTA Pro 3 has a 4kWh battery capacity, enough to cover essential household electricity needs during an outage. Expand capacity up to 12kWh with two compatible DELTA Pro 3 Smart Extra Batteries for multi-day backup during longer outages.

X-Fusion technology lets DELTA Pro 3 deliver its full 4000W AC output even when grid input is limited, with stable pure sine wave power for sensitive household appliances. Under 10ms UPS switchover protects routers, modems, NAS systems, servers, freezers, and other devices that cannot tolerate even brief power interruptions.

Explore the Secure Feeling EcoFlow Brings You

Crafted with automotive-grade LFP cells, the DELTA Pro 3 features an IP65-rated battery pack, resisting impacts, water, dust, and fire risks. With 4000 cycles to 80% capacity, the battery delivers up to 11 years of daily power. X-Guard BMS monitors 40 safety indicators around the clock and is app-managed for smart, secure energy. Cell-to-Chassis (CTC) design with a UL-certified 5VA fireproof shell adds another layer of resilience.

*The 11-year figure is based on EcoFlow's lab testing at a 0.5 °C charge/discharge rate at 25°C ambient. Real-world lifespan depends on usage patterns, depth of discharge, ambient temperature, and other factors. The IP65 rating applies to the internal battery pack only. The main unit is rated IP20 and should not be exposed to rain or used in wet outdoor environments without shelter.

Charge Up Fast, and Everywhere

EcoFlow's X-Stream fast charging technology recharges the DELTA Pro 3 quickly from a standard NZ wall outlet. Combine AC charging with solar input to reach even faster top-ups when you need to refuel in a hurry.

Effortless Control with the EcoFlow App

Monitor and control your DELTA Pro 3 from anywhere via the EcoFlow app over Wi-Fi or Bluetooth. Track battery level, real-time input and output, charging speed, X-Boost settings, AC timeout, GFCI support, and more from a single dashboard. Receive in-app notifications, firmware updates, and troubleshooting guidance directly to your phone.

Built for Mobility

Wide wheels, an ergonomic telescopic handle, and a compact form factor make the 51.5kg DELTA Pro 3 practical to move around the house, between rooms, or in and out of a motorhome or trailer. Magnetic sliding doors keep the AC sockets covered when not in use, protecting them from dust and accidental knocks.

Multiple Use Scenarios

From whole-home backup during NZ winter outages, to motorhome and caravan power on the road, off-grid bach setups with solar input, or job sites running heavy-duty tools, the DELTA Pro 3 handles a wide range of high-demand applications.

6 Unique and 18 Combo Charging Methods

The DELTA Pro 3 supports AC wall, dual-PV solar, car cigarette lighter, alternator charging (via adapter), smart generator (via adapter), and EV charging. Combine multiple sources at once for faster top-ups in almost any situation.

Whisper-Quiet Operation

X-Quiet technology keeps noise as low as 30dB under loads up to 2000W. Quiet enough to run inside the house overnight without disturbing sleep, and far quieter than a petrol or diesel backup generator. Ideal for indoor backup, bach use, or anywhere noise is a concern.

What's in the Box

Pairs Well With

The DELTA Pro 3 is built to anchor a larger EcoFlow system. Expand capacity with the EcoFlow DELTA Pro 3 Smart Extra Battery (4096Wh) (up to 2 supported for 12kWh total). Pair with the EcoFlow 400W Lightweight Portable Solar Panel for fast solar charging, or with the EcoFlow 400W Rigid Solar Panels for a permanent rooftop or off-grid install.

For motorhome and 4WD use, add the EcoFlow 800W Alternator Charger with the EcoFlow DELTA Pro to Smart Generator Adapter (required to connect via the Extra Battery Port) for fast drive-and-charge top-ups while you travel.
