EcoFlow DELTA Pro Ultra Inverter

7200W Continuous Output | 10.8kW Surge | Up to 5600W Solar Input | 120/240V Dual Voltage | 0ms Online UPS | Expandable to 30kWh per Inverter

The EcoFlow DELTA Pro Ultra Inverter is the powerful control and conversion core of the DELTA Pro Ultra whole-home energy system. Designed for home backup, emergency power, solar energy storage, RVs, workshops, and off-grid applications, the inverter delivers up to 7200W of continuous AC output and 10.8kW of surge power in the US configuration. Pair it with a compatible DELTA Pro Ultra Battery to create a high-capacity energy system, with one inverter supporting up to 30kWh of battery storage. Multiple inverter systems can scale even further for whole-home energy requirements.

7200W of Powerful AC Output

The DELTA Pro Ultra Inverter provides 7200W of continuous AC output with up to 10.8kW of surge power, giving you the ability to operate demanding household appliances and equipment.

Its 120/240V output makes it suitable for a wide range of home loads, including refrigerators, freezers, air conditioners, kitchen appliances, power tools, pumps, electronics, and other compatible equipment.

Whole-Home Power in One System

The DELTA Pro Ultra Inverter is designed as part of a complete home-energy system rather than as a standalone battery. Connect compatible DELTA Pro Ultra Batteries to create a scalable backup system capable of supporting essential household circuits and larger home loads.

When integrated with compatible EcoFlow home backup equipment, it provides a centralized solution for managing stored and renewable energy during outages.

6kWh Battery Capacity per DELTA Pro Ultra Battery

The compatible DELTA Pro Ultra Battery provides 6144Wh (6.144kWh) of energy storage. A single inverter can support up to five batteries, providing approximately 30kWh of total capacity.

This modular design lets you choose the amount of energy storage based on your household's requirements rather than committing to a fixed-capacity system.

Scale Up to 90kWh

For larger whole-home energy systems, EcoFlow allows multiple DELTA Pro Ultra inverter configurations. A system with up to three inverters and 15 batteries can reach approximately 90kWh of total battery capacity and 21.6kW of combined output.

This makes the platform suitable for homeowners who need substantially more backup capacity for extended outages or larger energy requirements.

Up to 5600W of Solar Input

The DELTA Pro Ultra Inverter features a high-capacity solar charging architecture with up to 5600W of total PV input.

It provides two independent solar inputs:

• High-PV Input: 80–450V, 15A, up to 4000W
• Low-PV Input: 30–150V, 15A, up to 1600W

This allows compatible solar arrays to provide substantial renewable charging power and helps maximize solar energy collection during periods of strong sunlight.

120/240V Dual-Voltage Power

The US version provides 120/240V AC output, making the inverter suitable for both standard household appliances and compatible higher-voltage equipment.

The output configuration includes 120V outlets and a 120/240V 30A connection, providing greater flexibility when building a home backup system.

0ms Online UPS Protection

For critical electronics, the DELTA Pro Ultra Inverter offers 0ms online UPS operation in the US configuration. This helps maintain continuous power for compatible sensitive equipment when utility power is interrupted.

It is particularly useful for computers, networking equipment, servers, NAS systems, home offices, security equipment, and other critical electronics.

Pure Sine Wave AC Power

The inverter provides pure sine wave AC output, delivering stable electricity suitable for compatible household appliances and sensitive electronic equipment.

This makes it suitable for powering everything from everyday electronics to demanding home appliances and professional equipment.

Power Multiple Devices Simultaneously

The DELTA Pro Ultra Inverter is equipped with multiple AC, USB, and DC outputs, allowing you to power different types of equipment at the same time.

The US configuration includes:

• 4 × 120V AC outlets
• 1 × 120V 30A outlet
• 1 × 120/240V 30A outlet
• 2 × USB-C ports
• 2 × USB-A ports
• 1 × 12V DC output

The two USB-C ports support up to 100W each, while the 12V DC output provides up to 378W.

100W USB-C Fast Charging

Two integrated 100W USB-C ports provide convenient high-power charging for compatible laptops, tablets, cameras, gaming devices, and other USB-C electronics.

With up to 200W of combined USB-C output, you can charge modern portable devices directly from the inverter without using additional AC adapters. 

378W 12V DC Output

The integrated 12.6V DC output supports up to 30A and 378W, providing a convenient power source for compatible 12V equipment.

This is useful for applications such as compatible DC appliances, accessories, and other low-voltage equipment.

Flexible AC Charging and Bypass Operation

The DELTA Pro Ultra Inverter supports AC charging and bypass operation, allowing it to integrate into different home-energy configurations.

The US model supports 100–120V and 200–240V AC inputs, while its power input/output connection supports up to 30A under supported conditions.

Smart Energy Management

The DELTA Pro Ultra Inverter supports Wi-Fi and Bluetooth connectivity, allowing users to monitor and manage their energy system through EcoFlow's connected ecosystem.

Depending on the system configuration, users can monitor energy flow, battery status, charging activity, and power consumption from a compatible mobile device.

Built for Home Backup

The DELTA Pro Ultra Inverter is designed to work as part of a comprehensive whole-home backup system. When paired with compatible batteries and EcoFlow home-energy accessories, it can provide backup power for essential circuits during utility outages.

Its high output and expandable battery architecture allow homeowners to build a system around their actual energy requirements.

High Solar + Generator Compatibility

The DELTA Pro Ultra ecosystem supports multiple energy sources, including solar power and compatible generator charging.

This allows users to combine renewable energy with backup generation when needed, creating greater flexibility during prolonged outages and off-grid situations.

Quiet Operation

Despite its high power output, the DELTA Pro Ultra Inverter is designed for quiet operation, with a rated noise level of less than 30dB under specified conditions.

This makes it considerably more suitable for residential environments than traditional fuel-powered generators that rely on combustion engines.

IP54 Protection

The DELTA Pro Ultra Inverter has an IP54 rating when the protective covers are properly closed, providing protection against dust ingress and water splashes.

This added protection makes the inverter suitable for a wider range of home-energy and semi-outdoor installations when used according to EcoFlow's environmental requirements.

Designed for Extreme Temperatures

The DELTA Pro Ultra Inverter supports charging and discharging within a temperature range of approximately -20°C to 45°C (-4°F to 113°F).

This broad operating range provides flexibility for use in different climates and environments.

A Scalable Foundation for Energy Independence

The DELTA Pro Ultra Inverter gives you the flexibility to build an energy system around your needs. Start with one inverter and compatible DELTA Pro Ultra Battery, then expand the battery capacity as your energy requirements grow.

With up to 30kWh per inverter and up to 90kWh across a three-inverter system, the platform can support everything from essential backup to comprehensive whole-home energy storage.

Power for Home, Work, and Off-Grid Applications

Whether you're preparing for extended blackouts, building a solar-powered home backup system, powering an RV, operating equipment at a remote site, or seeking greater energy independence, the EcoFlow DELTA Pro Ultra Inverter provides the high-output conversion and energy-management capabilities needed for demanding applications.

With 7200W continuous output, 10.8kW surge power, 5600W solar input, 120/240V output, 0ms online UPS, and scalable battery capacity, it provides a strong foundation for a modern backup power system.
