The EcoFlow DELTA Pro Ultra X inverter delivers 12kW continuous power output as the foundation of scalable whole-home backup systems. This professional-grade inverter converts stored battery power into household AC electricity while managing solar input, grid charging, and intelligent load distribution. Combine with DELTA Pro Ultra X batteries (sold separately) to create custom configurations from 12.288kWh to 180kWh total capacity.
The DELTA Pro Ultra X inverter provides 12kW continuous output (120/240V, 60Hz) with parallel capability supporting up to 3 units for 36kW combined power. Each inverter handles up to 61.44kWh of battery storage (10 battery modules) and features dual PV ports supporting 10kW solar input (80-500V, 5,000W max per port). Adaptive Start Technology handles surge loads up to 45kW for heavy motor starts, while ultra-fast UPS switching operates in sub-10ms standalone mode.
Build your exact backup solution starting with one inverter and minimum 2 batteries (12.288kWh), then expand as needs grow. Single inverter configurations scale from 12.288kWh to 61.44kWh capacity. Multi-inverter setups deliver 24kW (2 inverters) or 36kW (3 inverters) with up to 180kWh total storage. The modular design enables independent scaling of power output and storage capacity.
Integrated dual MPPT solar controllers optimize renewable energy harvest across various panel configurations. Time-of-use optimization automates charging during off-peak rates. Smart Home Panel 3 compatibility enables circuit-level control with under 20ms UPS switching. Remote monitoring and app-based control provide complete energy management from anywhere.
IP54 weather-resistant housing protects components in outdoor installations. Silent operation under 30dB at 0.5m distance ensures unobtrusive performance. Compact dimensions of 675 × 475 × 230mm (26.6 × 18.7 × 9.06 inches) and 34.5kg (76 lbs) weight facilitate flexible installation options. Wide operating temperature range accommodates various climates.
The DELTA Pro Ultra X inverter requires battery modules to function as a backup power system. Plan your complete solution: determine power needs (12kW, 24kW, or 36kW), calculate runtime requirements based on 6.144kWh per battery module, add optional solar panels for energy independence, and integrate optional Smart Panel for automated circuit control. The 5-year warranty and commercial specifications deliver decades of reliable service.
Ideal for whole-home backup covering essential circuits through complete home coverage including HVAC, pool equipment, and Level 2 EV charging. Solar system integrators benefit from 10kW solar input capacity with intelligent MPPT tracking. Commercial and critical infrastructure applications utilize multi-inverter configurations for data centers, medical facilities, and critical systems requiring uninterrupted operation.
