24.5kWh of High-Capacity Energy Storage

With 4 × 6,144Wh DELTA Pro Ultra Batteries, this configuration provides approximately 24,576Wh of total battery capacity.

The large energy reserve allows you to keep essential household appliances and systems operating for significantly longer during outages compared with smaller battery configurations.

Power Your Home During Outages

The DELTA Pro Ultra Inverter provides 7,200W of continuous AC output, giving you the power needed to operate a broad range of household appliances.

Power compatible refrigerators, freezers, lighting, televisions, Wi-Fi equipment, kitchen appliances, computers, HVAC systems, and other essential loads during a grid interruption.

120V & 240V Power

The DELTA Pro Ultra provides 120V/240V AC power, allowing the system to support both standard household electronics and compatible high-voltage appliances.

This makes the system suitable for more comprehensive home backup applications where both 120V and 240V loads need to be supported.

Extended Runtime with Four Batteries

The inclusion of four DELTA Pro Ultra Batteries provides a substantial energy reserve for prolonged outages.

With approximately 24.6kWh of stored energy, you can run essential household loads for longer periods before needing to recharge. Actual runtime depends on power consumption, connected appliances, battery condition, and environmental conditions.

Expandable Up to 30kWh

This configuration already provides approximately 24.6kWh, while one DELTA Pro Ultra Inverter can support up to 30kWh of battery capacity.

Add another compatible DELTA Pro Ultra Battery to reach the inverter's maximum supported battery capacity, subject to system specifications and configuration.

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 large battery bank using compatible solar panels.

With an appropriately sized solar array, solar energy can replenish stored power during daylight hours and help extend backup runtime during prolonged outages.

Multiple Charging Options

The DELTA Pro Ultra platform supports multiple charging methods, providing flexibility for everyday use and emergency situations.

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

Long-Lasting LFP Battery Technology

All four DELTA Pro Ultra Batteries use Lithium Iron Phosphate (LFP) battery chemistry.

EcoFlow specifies a battery life of 3,500 cycles to 80% of original capacity, providing a durable energy-storage platform designed for long-term use.

Power High-Demand Appliances

With 7,200W of continuous output, the system can handle demanding household equipment that may exceed the capabilities of smaller portable power stations.

Depending on the appliance and installation requirements, compatible loads may include:

• Central air conditioning
• Refrigerators and freezers
• Washing machines
• Kitchen appliances
• Lighting systems
• Televisions
• Computers and workstations
• Wi-Fi routers and networking equipment
• Communication systems
• Other compatible 120V and 240V appliances

X-Fusion Technology for Stable Power

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

The DELTA Pro Ultra can provide up to 7,200W of continuous output from its inverter under supported operating conditions, helping manage changing household power demands.

0ms Online UPS

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

This provides uninterrupted power for supported equipment and can be particularly useful for sensitive electronics such as computers, networking equipment, and other devices that benefit from continuous power.

Quiet Operation at Lower Loads

The DELTA Pro Ultra is designed for quiet operation when power demands are lower.

EcoFlow specifies 0dB operation below 2,200W, helping minimize operating noise while powering lighter household loads.

Automatic Battery Self-Heating

The DELTA Pro Ultra Batteries feature automatic self-heating for cold-weather operation.

The system can automatically activate battery self-heating when temperatures fall below 32°F, helping maintain suitable battery operating conditions in colder environments.

UL 9540 & UL 1973 Certified

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.

This certification makes the system suitable for residential energy-storage applications where certified equipment is required.

Automatic Whole-Home Backup

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

When properly installed, Smart Home Panel 2 can automatically switch supported household circuits to battery power when grid electricity fails, providing a convenient whole-home backup experience.

Solar + Battery Backup for Extended Outages

The combination of approximately 24.6kWh of stored energy and up to 5.6kW of solar input makes this configuration particularly well suited for prolonged outages.

Solar panels can recharge the battery bank during daylight hours, while stored energy can power your home when solar production is unavailable.

Reliable Power Without Fuel

The DELTA Pro Ultra operates using stored battery energy rather than gasoline or diesel.

It produces no exhaust fumes during battery operation and provides quiet power for your home. When charged from solar panels, it can also provide a renewable-energy backup solution.

Designed for Home Energy Independence

With a large battery bank and solar-charging capability, this configuration can help homeowners reduce reliance on grid electricity during suitable conditions.

Use stored solar energy during outages, at night, or during periods when grid electricity is unavailable.

Smart Home Energy Management

When connected to compatible EcoFlow home-energy equipment, DELTA Pro Ultra can support energy monitoring and management.

The EcoFlow ecosystem allows homeowners to monitor energy usage and manage stored electricity more effectively.

Stackable, Modular Energy Storage

The four-battery configuration uses DELTA Pro Ultra's modular design, allowing the batteries to be organized as part of a dedicated home energy-storage system.

The modular architecture also allows you to add compatible batteries as your energy requirements change, up to the maximum supported capacity.

Ideal for Extended Power Outages

With approximately 24.6kWh of battery storage, this system is designed for homeowners who want substantial backup capacity for:

• Extended blackouts
• Severe weather
• Grid interruptions
• Emergency preparedness
• Whole-home backup
• Solar energy storage
• Increased energy independence
• High-demand household loads

Important Installation Consideration

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

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