One System That Powers It All.
DELTA Pro Ultra’s whole-home generator system combines a high-performance inverter with a robust battery module. A single inverter delivers both 120V & 240V with an impressive 7200W output, capable of running nearly any major household appliance — including a 3-ton central AC unit. Expand to three inverters for an extraordinary 21.6kW AC output, ensuring full home comfort even during outages. The system maintains a full 7200W output while charging, providing uninterrupted performance.

Exceptional Power Security.
Starting with a 6kWh battery that provides roughly two days of essential power, the system can scale up to 15 batteries, achieving an enormous 90kWh capacity. For a standard North American home, this equates to over 30 days of essential backup power, offering true long-term security and peace of mind.

Multiple Fast-Charging Options.
A single 6kWh battery can recharge in as little as 2 hours — faster than any comparable 6kWh solar generator. Choose from multiple charging methods, including EV charging stations, solar panels, wall outlets, or portable gas generators, giving you complete flexibility wherever you are.

Smart Home Power Management.
With the EcoFlow app, you can customize and prioritize specific home circuits, extending backup duration when needed. Beyond outages, the system intelligently analyzes energy usage, helps reduce peak-rate consumption, and maximizes savings by utilizing solar power whenever available.

Uninterrupted, Quiet Operation.
Featuring an online UPS with 0-ms transfer time, the system safeguards sensitive electronics and ensures continuous power during grid failures or voltage fluctuations. All cooling fans remain off for the first 30 minutes during loads up to 2000W, providing silent operation for everyday comfort.
