Plug and play home backup power
Easily chain together two DELTA Pros using the Double Voltage Hub and plug in to your power inlet box for home security and comfort during a power outage. The DELTA Pro and Double Voltage Hub bundle provide a simple and convenient home battery system without rewiring or running dangerous extension cables through your home.
A clean power alternative
Replace noisy, smoky generators with a silent and fume-free portable home battery solution. Unlike generators, these batteries can be used inside to run all your essentials during a blackout. And, with the help of solar energy, they can easily be recharged during an extended outage.
Power your entire home with 240V and 7200W
Battery backup has never offered this kind of output. The Double Voltage Hub doubles the AC output to 7200W, so you can run 99% of all home appliances, including high-wattage ones like a clothes dryer (5000W). Note: The Double Voltage Hub requires two EcoFlow DELTA Pro units.
Start from 7.2kWh
With DELTA Pro’s expandable capacity, this setup can expand to 25kWh of energy storage with Extra Batteries and Smart Generators.
Recharge your EV anytime, anywhere.
Keep going for miles when your electric vehicle runs out of battery. Either at home or on the go, DELTA Pro will have you back on the road in no time.
How to use the Double Voltage Hub
A simple connection.
