One Powers All. The unit of DELTA Pro Ultra whole house generator includes an inverter and a battery. One inverter supports 120V & 240V and has an exceptional 7200W output, allowing you to run almost any heavy household appliance, even a 3-ton central air conditioner. Triple the inverters for an incredible 21.6kW AC output, allowing you to live life to the fullest even during an outage. The electric generator achieves a total 7200W output even during charging.
Strong Power Security. Scalable from one battery of 6144Wh, two days of essential power, all the way to 15, it multiplies the energy to a gigantic 90kWh. For a standard North American household, that’s over 30 days of essential power secured.
Customize Your Home Power. Use the EcoFlow app to priolritize specific circuits in your home, extending your backup even longer. For more than just blackouts, it intelligently analyses your home power usage to offset peak rates while utilizing solar to lower energy bills.
Multi Ways to Charge. One battery of 6144Wh can be fully recharged in 2 hours. Faster than any other 6kWh solar generator. Users can choose among electric vehicle piles, solar, wall outlets or outdoor generators for charging.
Uninterrupted Life. Online UPS with 0-ms transfer time, offering 24/7 protection for sensitive electrical devices against power disturbances or grid failure. All fans are off for the first half hour of outputting 2000W, giving you absolute silence for tranquility in everyday life.
Kindly note that the inverter and the battery will arrive in individual packages.
