EcoFlow DELTA Pro Ultra Inverter 7200W, 10.8kW Surge, Whole-Home Backup Inverter, Wi-Fi & 4G – EF-DELTAPROULTRA

Product details

The EcoFlow DELTA Pro Ultra Inverter is designed as the high-power inverter component of the EcoFlow DELTA Pro Ultra whole-home energy system. It delivers 7200W of continuous AC output and up to 10.8kW of AC surge power, providing the power conversion and output capability required for demanding household appliances and backup applications.

The inverter uses pure sine wave AC output and supports 120V/240V at 60Hz for the applicable US configuration. It is designed to work with DELTA Pro Ultra batteries to create a scalable whole-home energy storage system.

A single DELTA Pro Ultra system can support up to 30kWh of expandable battery capacity using up to five compatible DELTA Pro Ultra batteries. For larger installations, up to three inverters can be combined with the EcoFlow Smart Home Panel 2 to achieve a system output of up to 21.6kW and total system capacity of up to 90kWh using 15 compatible batteries.

For solar charging, the DELTA Pro Ultra Inverter features two PV input channels with a combined maximum solar input of 5600W. The high-voltage PV input supports up to 4000W, while the low-voltage PV input supports up to 1600W. This allows the system to work with suitable rooftop solar or portable solar configurations.

The inverter also supports multiple energy sources. AC charging supports both 100?120V and 200?240V inputs, while the EcoFlow system can also integrate compatible generators and EV charging solutions. EcoFlow states that the system can support up to 7.2kW EV charging with the appropriate EV X-Stream Adapter.

For backup applications, DELTA Pro Ultra provides Backup UPS with less than 20ms transfer time, while the Online UPS configuration can provide 0ms transfer time. This makes the system suitable for compatible critical loads and whole-home backup applications.

The inverter features IP54 protection, intelligent thermal management, and an operating temperature range of -20?C to 45?C. Connectivity includes Wi-Fi, Bluetooth and 4G, enabling smart monitoring and control through EcoFlow’s connected energy ecosystem.
