The EcoFlow DELTA Pro Ultra delivers professional-grade home backup power with a base 6kWh capacity expandable up to 90kWh. This system combines a 7200W pure sine wave inverter with LFP battery technology rated for 3500+ cycles to 80% capacity, providing reliable power for essential appliances and heavy-duty equipment during outages or off-grid applications.
The inverter provides 7200W continuous AC output with 120V and 240V capabilities, sufficient to run 3-ton central air conditioners (up to 120A LRA), electric dryers, water heaters, and other high-draw appliances. X-Fusion technology maintains consistent 7200W output regardless of input source. Scale up to 21.6kW by connecting three inverters with the EcoFlow Smart Home Panel 2 for whole-home coverage.
Dual MPPT charge controllers accept 5.6kW solar input per unit (expandable to 16.8kW with three inverters). High-voltage MPPT handles 80-450V at 4000W max, while low-voltage MPPT accepts 30-150V at 1600W max. This configuration enables rapid recharging from both rooftop and portable solar arrays.
Built-in online UPS functionality provides instantaneous 0ms switchover during grid failures, protecting sensitive electronics and medical equipment. The system operates silently at 0dB under 2000W loads, eliminating generator noise during extended outages while maintaining continuous power to connected devices.
Charge from AC grid (3000W max at 240V), solar panels (5600W), gas generators, or EV charging stations. The 8800W Multicharge feature enables two-battery charging in approximately 2 hours when combining multiple input sources simultaneously.
IP54 dust and splash protection allows installation in garages and utility spaces. Operating temperature range of -4°F to 113°F (-20°C to 45°C) ensures functionality in extreme climates. X-Cooling thermal management system maintains optimal battery temperature during sustained high-load operation.
LFP battery chemistry with intelligent Battery Management System provides protection against over-temperature, over-voltage, low-voltage, overload, short circuit, and overcurrent conditions. Both inverter and battery include comprehensive 5-year warranty coverage with 10-year shelf life rating.
Package includes DELTA Pro Ultra Inverter, 6kWh battery, portable stand, four support legs, four side-mount casters, assembly tools, solar charging cables, AC charging cable (C20), battery connection cable, and complete documentation. The stackable design fits in standard utility closets and garage spaces.
