6.1kWh of Reliable Energy Storage

The included DELTA Pro Ultra Battery provides 6,144Wh of energy storage, giving you a substantial reserve of power for emergencies and everyday energy needs.

Store electricity from the grid or compatible solar panels and use the stored energy when utility power is unavailable or when you want to reduce reliance on the grid.

7.2kW of Powerful Continuous Output

The DELTA Pro Ultra Inverter delivers up to 7,200W of continuous AC output, providing significantly more power than conventional portable power stations.

This high output makes the system suitable for demanding household loads, including refrigerators, freezers, kitchen appliances, lighting, computers, networking equipment, and compatible HVAC systems.

120V & 240V Power for Your Home

With support for 120V and 240V AC power, DELTA Pro Ultra can operate a broad range of household equipment.

Power standard electronics and appliances while also supporting compatible higher-voltage loads that require 240V power.

Power Essential Appliances During Outages

When the grid goes down, DELTA Pro Ultra can provide battery power for the appliances and systems you rely on most.

Depending on the power requirements, use it for:

• Refrigerators and freezers
• Lighting
• Wi-Fi routers and networking equipment
• Televisions
• Computers
• Kitchen appliances
• Washing machines
• Communication equipment
• Compatible HVAC systems
• Other compatible 120V and 240V loads

Actual runtime depends on the connected load and operating conditions.

Expandable Up to 30kWh

Start with 6,144Wh of battery storage and expand the system as your energy requirements grow.

A single DELTA Pro Ultra Inverter supports up to 30kWh of battery capacity, allowing additional compatible DELTA Pro Ultra Batteries to be added without replacing the inverter.

This makes the system a flexible long-term investment for growing backup requirements.

Harness Up to 5.6kW of Solar Energy

The DELTA Pro Ultra Inverter supports up to 5,600W of solar input, allowing you to recharge the battery using compatible solar panels.

Solar charging can help replenish stored energy during daylight hours and extend backup capability during prolonged outages.

High-Power Solar Charging

The inverter's solar input architecture supports both high- and low-voltage PV configurations.

With compatible solar equipment, you can build a substantial solar array around the system and take advantage of available sunlight to replenish the 6.1kWh battery.

Multiple Ways to Recharge

DELTA Pro Ultra supports multiple charging methods, providing flexibility in both normal and emergency situations.

Depending on the equipment and configuration, recharge using AC power, solar energy, generators, and other supported charging solutions.

This gives you multiple options for restoring battery capacity when one energy source isn't available.

Long-Lasting LFP Battery Technology

The DELTA Pro Ultra Battery uses Lithium Iron Phosphate (LFP) battery chemistry, designed for durability and long-term energy storage.

EcoFlow specifies 3,500 cycles to 80% of the original capacity, providing a dependable battery platform for regular backup and energy-management applications.

X-Fusion Technology for Stable Power

EcoFlow's X-Fusion technology is designed to provide stable and consistent power for connected appliances.

The inverter can deliver up to 7,200W of continuous output under supported operating conditions, helping the system handle changing household power demands.

0ms Online UPS

For compatible equipment, DELTA Pro Ultra supports 0ms Online UPS operation.

This is particularly useful for sensitive electronics such as computers, networking equipment, and other devices that benefit from uninterrupted power.

The system also supports a Backup UPS mode with transfer time under 20ms for supported applications.

Quiet Operation

The DELTA Pro Ultra is designed to operate quietly when power demands are lower.

EcoFlow specifies 0dB operation below 2,200W, helping minimize noise while the system powers lighter loads.

Automatic Battery Self-Heating

The DELTA Pro Ultra Battery features automatic self-heating for colder environments.

The battery can automatically activate its heating function when temperatures fall below 32°F, helping maintain suitable operating conditions in cold weather.

Automatic Whole-Home Backup

Pair DELTA Pro Ultra with the EcoFlow Smart Home Panel 2 to integrate the system with your home's electrical system.

When properly installed, the Smart Home Panel 2 can automatically transfer supported household circuits to battery power when grid electricity fails.

This creates a convenient backup experience without requiring you to manually connect individual appliances.

UL 9540 & UL 1973 Certified

Safety is an important consideration for residential energy-storage systems.

The DELTA Pro Ultra platform is certified to UL 9540 and UL 1973, providing recognized safety certification for the energy-storage system and battery components.

Solar + Battery Backup

Pair the DELTA Pro Ultra with compatible solar panels to create a renewable home energy system.

During daylight hours, solar energy can replenish the battery while powering compatible household loads. Stored energy can then be used at night or when sunlight is unavailable.

Reliable Power Without Fuel

Unlike traditional gasoline or diesel generators, DELTA Pro Ultra operates using stored battery energy without combustion or exhaust fumes.

When charged from solar energy, it can provide a clean and quiet renewable-energy backup solution for your home.

Designed to Grow With Your Energy Needs

The 1 × Inverter + 1 × Battery configuration provides an excellent starting point for homeowners who want a powerful backup system without immediately purchasing a large battery bank.

As energy requirements increase, additional compatible batteries can be added to increase runtime and storage capacity.

Ideal for Emergency Preparedness

The DELTA Pro Ultra is designed for homeowners preparing for:

• Power outages
• Severe weather
• Grid interruptions
• Emergency situations
• Solar energy storage
• Home backup
• Increased energy independence
• High-demand household appliances

Its expandable design allows the system to become larger as your backup needs change.

Smart Home Energy Management

When integrated with compatible EcoFlow home-energy equipment, DELTA Pro Ultra can provide energy monitoring and management features through the EcoFlow ecosystem.

Monitor energy usage and manage stored electricity to make better use of available battery capacity.

Compact, Modular Design

The DELTA Pro Ultra uses a modular architecture that separates the inverter and battery, making it possible to expand storage without replacing the entire system.

The 1 × Inverter + 1 × Battery configuration provides a straightforward starting point for a larger home energy-storage system.

Important Installation Consideration

For automatic whole-home backup, the EcoFlow Smart Home Panel 2 and appropriate electrical installation are required.

Whole-home electrical integration should be completed according to applicable local electrical codes and by a qualified professional where required.

Smart Home Panel 2, solar panels, and certain connection or installation accessories may be sold separately depending on the package.
