xEcoFlow DELTA Pro Ultra (1 × Inverter + 2 × Batteries)
12.3kWh Capacity | 7.2kW Continuous Output | 120V/240V Power | Up to 5.6kW Solar Input | Expandable Up to 30kWh | Whole-Home Backup
The EcoFlow DELTA Pro Ultra (1 × Inverter + 2 × Batteries) combines 1 × DELTA Pro Ultra Inverter with 2 × DELTA Pro Ultra Batteries to create a high-capacity home backup and energy-storage system. With 12,288Wh of total battery capacity and 7,200W of continuous AC output, this configuration is designed to power essential household appliances and demanding loads during outages. Its 120V/240V output, solar charging capability, LFP battery technology, fast UPS functionality, and expandable architecture make it a flexible foundation for whole-home backup and long-term energy independence.
12.3kWh of Energy Storage
The two included DELTA Pro Ultra Batteries provide 6,144Wh each, giving the system a combined capacity of 12,288Wh.
This substantial energy reserve provides longer runtime for household appliances and essential circuits compared with a single-battery configuration, making it well suited for extended power outages and emergency preparedness.
7.2kW of Continuous Power
The DELTA Pro Ultra Inverter delivers up to 7,200W of continuous AC output, providing enough power for many high-demand household appliances.
Power compatible refrigerators, freezers, lighting, kitchen appliances, televisions, computers, networking equipment, HVAC systems, and other household loads.
120V & 240V Household Power
With 120V/240V AC output, DELTA Pro Ultra can support both standard household electronics and compatible high-voltage appliances.
This provides greater flexibility for whole-home backup applications where different appliances require different voltage levels.
Keep Essential Appliances Running
During a grid outage, the DELTA Pro Ultra can supply stored battery power to compatible household loads.
Use it to keep important systems and appliances operating, including:
- Refrigerators and freezers
- Lighting
- Wi-Fi routers and networking equipment
- Televisions
- Computers and workstations
- Kitchen appliances
- Washing machines
- Communication equipment
- Compatible HVAC systems
- Other compatible 120V and 240V appliances
Actual runtime depends on the connected load, battery capacity, and operating conditions.
Extended Runtime with Two Batteries
The 2-battery configuration doubles the storage available from a single 6.1kWh battery.
With 12.3kWh of total capacity, the system can keep essential loads powered for longer before requiring a recharge. Solar charging can further extend runtime when adequate sunlight is available.
Expandable Up to 30kWh
Start with 12,288Wh of battery capacity and add compatible DELTA Pro Ultra Batteries as your energy needs grow.
A single DELTA Pro Ultra Inverter supports up to 30kWh of battery capacity, allowing you to expand storage without replacing the inverter.
Harness Up to 5.6kW of Solar Energy
The DELTA Pro Ultra Inverter supports up to 5,600W of solar input, providing substantial solar-charging capability.
Connect compatible solar panels to replenish the two batteries during daylight hours and maintain stored energy during prolonged outages.
Multiple Charging Options
DELTA Pro Ultra supports multiple charging methods, providing flexibility for both everyday energy management and emergency backup.
Depending on the configuration and available accessories, recharge using AC power, solar energy, generators, and other supported charging solutions.
Long-Lasting LFP Battery Technology
Both DELTA Pro Ultra Batteries use Lithium Iron Phosphate (LFP) battery chemistry.
EcoFlow specifies 3,500 cycles to 80% of the original capacity, providing a durable energy-storage platform designed for long-term use.
X-Fusion Technology for Stable Power
EcoFlow's X-Fusion technology is designed to provide stable and consistent AC power for connected equipment.
The inverter delivers up to 7,200W of continuous output under supported conditions, helping handle changing household power demands.
0ms Online UPS
For compatible equipment, DELTA Pro Ultra supports 0ms Online UPS operation.
This makes the system suitable for sensitive electronics that benefit from uninterrupted power, including computers, networking equipment, and other critical devices.
The system also supports Backup UPS switching under 20ms for supported applications.
Quiet Operation
The DELTA Pro Ultra is designed for quiet operation at lower power loads.
EcoFlow specifies 0dB operation below 2,200W, helping minimize noise when the system is powering lighter household loads.
Automatic Battery Self-Heating
The DELTA Pro Ultra Batteries feature automatic self-heating for cold-weather operation.
The batteries can activate their heating function when temperatures fall below 32°F, helping maintain suitable battery operating conditions in colder environments.
Automatic Whole-Home Backup
Pair the DELTA Pro Ultra with the EcoFlow Smart Home Panel 2 to connect the system to your home's electrical system.
When professionally installed and configured, the Smart Home Panel 2 can automatically transfer supported household circuits to battery power when grid electricity fails.
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 makes the platform suitable for residential energy-storage applications where certified equipment is required.
Solar + Battery Backup for Extended Outages
Combining 12.3kWh of battery storage with up to 5.6kW of solar input makes this configuration well suited to extended power interruptions.
During daylight hours, solar panels can replenish the battery bank, while stored energy can provide power when solar production is unavailable.
Reliable Power Without Fuel
The DELTA Pro Ultra provides battery-based power without requiring gasoline or diesel during operation.
It produces no combustion exhaust and operates quietly, making it suitable for residential environments. When charged with solar energy, it can also provide a renewable backup-power solution.
Designed for Energy Independence
The combination of substantial battery storage, high output, and solar-charging capability allows homeowners to use stored energy strategically.
Store electricity when available and use the battery during outages, at night, or when solar production is low.
Smart Home Energy Management
When paired with compatible EcoFlow equipment, the DELTA Pro Ultra can support smart energy monitoring and management through the EcoFlow ecosystem.
Monitor energy usage and manage available battery capacity to make more efficient use of stored power.
Modular & Expandable Design
The separate inverter-and-battery architecture makes it easy to build a larger energy-storage system over time.
This 1 × Inverter + 2 × Batteries configuration provides a substantial starting point while leaving room for additional compatible batteries.
Ideal for Extended Power Outages
The 12.3kWh configuration is well suited for homeowners preparing for:
- Extended power outages
- Severe weather
- Grid interruptions
- Emergency situations
- Whole-home backup
- Solar energy storage
- High-demand household loads
- Greater energy independence
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.
