The EcoFlow DELTA Pro Ultra bundle delivers reliable whole-home backup power with a scalable design that grows with your needs. This complete system includes one inverter and one battery unit, providing 6kWh of capacity right out of the box, expandable up to 90kWh with additional batteries.
Starting with 6144Wh capacity, the DELTA Pro Ultra system scales to accommodate homes of any size. Stack up to 15 battery units to reach 90kWh of total capacity—enough to power essential appliances for extended outages lasting weeks. The compact, stackable design fits in garages and utility closets without consuming excessive space.
Each inverter delivers 7.2kW continuous output with support for both 120V and 240V appliances. Power everything from refrigerators to 3-ton central air conditioners. Connect three inverters with the optional Smart Home Panel 2 to achieve 21.6kW total output. The X-Fusion technology maintains consistent 7200W output regardless of load conditions.
The integrated 30-amp, 240V socket provides portable power for heavy-duty appliances including dryers, water heaters, and workshop equipment. This feature makes the DELTA Pro Ultra functional for both stationary home backup and mobile high-power applications.
The hybrid solar charging system combines high-voltage (80-450V, 4000W max) and low-voltage (30-150V, 1600W max) MPPT controllers for 5.6kW total solar input per unit. Three connected inverters can accept up to 16.8kW of solar power, enabling rapid recharging from renewable energy sources.
Charge from solar panels, AC grid power (up to 3000W), gas generators, or EV charging stations. The MultiCharge feature combines input sources for 8800W maximum charging speed, fully recharging two batteries in approximately 2 hours.
Online UPS functionality provides 0ms switchover time during power outages, protecting sensitive electronics without interruption. The system operates silently (0 dB) for loads under 2000W, with noise levels under 30 dB at higher loads.
Lithium Iron Phosphate (LFP) battery chemistry delivers 3500+ charge cycles to 80% capacity with a 10-year shelf life. The advanced Battery Management System (BMS) monitors temperature, voltage, and current to optimize safety and longevity. Each battery weighs 116.4 lb with dimensions of 26×18×8 inches.
IP54-rated protection guards against dust and water splashes. Operating temperature range from -4°F to 113°F ensures functionality in extreme conditions. The X-Cooling heat dissipation system maintains efficiency during continuous heavy loads, backed by a 5-year warranty on both inverter and battery.
Includes DELTA Pro Ultra inverter (70 lb), DELTA Pro Ultra battery, portable stand, four supporting legs, four side-mount casters, mounting hardware, solar charging cable, AC charging cable, battery connection cable, disassembly tool, and documentation.
Monitor and control your system via Wi-Fi and Bluetooth through the EcoFlow app. Optional 4G connectivity available. The built-in screen displays real-time power metrics and system status.
