EcoFlow DELTA 3 Ultra Portable Power Station 3072Wh, 3600W Output, 7200W Surge, LiFePO4 Battery, Solar Generator – EF-Delta3Ultra

Product details

The EcoFlow DELTA 3 Ultra 3072Wh Portable Power Station is a high-capacity portable energy solution designed for demanding home backup, outdoor, RV, camping, emergency, and off-grid applications.

With a 3072Wh / 3.072kWh rated battery capacity and 3600W continuous AC output, the DELTA 3 Ultra can power multiple devices and demanding appliances. It provides up to 7200W surge output, while X-Boost? 3.0 supports compatible heavy-duty appliances up to 4600W.

The DELTA 3 Ultra uses automotive-grade full-tab LFP (LiFePO4) battery cells and is designed for long-term use. EcoFlow estimates approximately 10 years of lifespan under proper usage based on its internal simulation testing. Its intelligent battery management system continuously monitors important parameters including state of charge, battery health and temperature.

For backup applications, the DELTA 3 Ultra features a less-than-10ms UPS auto-switch, helping keep compatible critical electronics such as NAS systems and servers running during power interruptions.

The power station supports four charging methods: wall charging, solar charging, generator charging and alternator charging. AC wall charging supports up to 1800W input, while solar charging supports up to 800W PV input. Under specified conditions, EcoFlow states that wall or generator charging can recharge the unit from 0?80% in approximately 89 minutes.

The DELTA 3 Ultra is also built for demanding environments. Its EV-grade Cell-to-Chassis (CTC) structure provides drop resistance and shock protection, while the system is designed to tolerate humid environments and temperatures ranging from -10?C to 45?C during discharge.

For quieter operation, EcoFlow’s X-Quiet? 3.0 technology provides noise levels of ?25dB at 600W under specified test conditions.

With Wi-Fi and Bluetooth connectivity, the EcoFlow App provides intelligent monitoring and control. Users can monitor energy usage and battery status and configure charging/discharging schedules.
