4000W Output with 120V/240V Dual Voltage

Power your entire world without compromise. The DELTA Pro 3 delivers a continuous 4000W pure sine wave output (8000W surge), capable of running 99% of heavy-duty appliances including central AC units, electric ovens, and well pumps. Its unique Split-Phase design supports both 120V and 240V devices from a single unit.

Industry’s Fastest Charging (7 Unique Methods)

Stay ready for anything. The DELTA Pro 3 can hit 80% charge in just 50 minutes via a standard AC wall outlet. It offers unparalleled flexibility with 7 unique charging methods, including 2600W Dual-PV Solar charging, EV charging station support (Level 2), and the EcoFlow Smart Generator.

10ms Ultra-Fast UPS (Uninterruptible Power Supply)

Protect your home’s most sensitive electronics. In the event of a blackout, the DELTA Pro 3 switches over in less than 10ms—faster than most dedicated UPS systems. This ensures that desktop PCs, servers, and medical equipment remain powered without a single flicker or reset.

Expandable Ecosystem (Up to 12kWh)

Grow your power as your needs change. A single DELTA Pro 3 can be expanded up to 12kWh by adding two Smart Extra Batteries. For whole-home backup, you can pair multiple units with the Smart Home Panel 2 to achieve up to 36kWh, providing over a week of essential energy.

Whisper-Quiet & Rugged IP65 Design

Designed for life, not just emergencies. The DELTA Pro 3 operates as quietly as 30dB (under 2000W), which is quieter than a typical refrigerator. It features an IP65-rated battery pack for dust and water resistance, along with an industrial-grade shell and a built-in telescoping handle for easy mobility.
