Description

3600W Output for Reliable, High-Performance Power

The EcoFlow DELTA 3 Ultra (3072Wh) provides a stable 3600W AC output with a 7200W surge capacity. With X-Boost™ 3.0 technology, it can support devices up to 4600W, making it suitable for running demanding appliances. Its inverter uses high-precision sampling every 33μs through a DSP chip, delivering a pure sine wave output that ensures consistent performance for sensitive electronics.

Hybrid Backup Extend Runtime With a Smart Generator

When paired with an EcoFlow Smart Generator (sold separately), the DELTA 3 Ultra extends backup duration for long outages or extended off-grid use. The system can intelligently alternate between fuel and battery power for continuous operation.

Fast Charging Options Up to 80% in 1.48 Hours

Enjoy four flexible charging methods with remote charging management. With up to 1800W input, the unit reaches 0–80% in just 1.48 hours. Storm Guard Mode (adjustable through the EcoFlow App) monitors severe weather alerts and automatically triggers AC charging so the system is ready before emergencies strike.

Engineered for Long Life and Everyday Reliability

Built with automotive-grade full-tab LFP battery cells and a durable exterior, the DELTA 3 Ultra is designed for long-term dependability. Its advanced BMS, powered by an ARM Cortex chipset, continuously monitors key parameters like SOC, SOH, and temperature to maintain optimal performance and extend battery lifespan.

Smart Monitoring & Easy Control

Track your energy usage, solar input, and system performance from one dashboard. Set custom charge/discharge schedules to take advantage of off-peak electricity rates for cost-efficient power management.
