Special Bundle: EcoFlow DELTA Pro Ultra X (2× Inverter + 4× Battery) + Smart Home Panel 3
Whole-Home Power. Unbound.
The EcoFlow DELTA Pro Ultra X Special Bundle provides a complete, high-capacity energy solution for whole-home backup and smart energy management. This bundle includes two DELTA Pro Ultra X inverters, four expandable batteries, and the Smart Home Panel 3, creating a robust system designed for reliability, flexibility, and intelligent control.
Built to handle high energy demands, the DELTA Pro Ultra X system delivers consistent power performance, automatic switching, and seamless integration with solar or grid power sources.
High Power Performance
The DELTA Pro Ultra X inverter provides up to 12 kW of continuous power at 120/240 V split-phase. When two inverters are used together, they deliver a combined output of up to 24 kW, making this configuration ideal for large homes, small businesses, or properties with heavy appliance loads.
Its Adaptive Start algorithm ensures smooth and stable operation, even for demanding equipment such as air conditioning systems or electric ranges.
Flexible Battery Capacity
This bundle includes four EcoFlow DELTA Pro Ultra X battery modules, each with a capacity of 6.144 kWh. Together, they provide 24.576 kWh of usable energy storage.
The batteries use advanced lithium iron phosphate (LFP) chemistry, known for its long cycle life, high safety, and excellent thermal stability. The modular design allows for future expansion as your energy requirements grow.
Smart Home Panel 3 Integration
The Smart Home Panel 3 connects the DELTA Pro Ultra X system directly to your home’s circuits, providing intelligent control and seamless backup capability.
