Description
Unlock true 240V whole-home backup capability with the EcoFlow DELTA Pro×2 + Double Voltage Hub + Transfer Switch — the most complete dual-DELTA Pro bundle available. This configuration combines two DELTA Pro power stations, the Double Voltage Hub that joins them into a unified 240V output system, and a transfer switch for automated home circuit failover — giving you everything needed for genuine 240V whole-home backup in a single purchase.
The Double Voltage Hub bridges two DELTA Pro units to produce a split-phase 240V output, enabling you to power appliances that a single 120V station cannot support — electric dryers, central HVAC systems, well pumps, and Level 2 EV chargers. Combined, the two DELTA Pros deliver 7,200Wh of LFP storage and 7,200W of combined AC output. Each station charges independently and accepts up to 1,600W of solar input, meaning both can recharge simultaneously from separate solar arrays. The Transfer Switch connects to your home panel for automated failover — when the grid goes down, selected circuits including 240V loads switch to the DELTA Pro system in milliseconds.
Each DELTA Pro is expandable to 25kWh with Smart Extra Batteries, and both can be monitored and controlled individually through the EcoFlow app. Storm Guard auto-charging monitors weather alerts and pre-charges both stations before severe weather. This is the most powerful portable-station-based whole-home backup solution available without a fixed installation.
Professional installation required for transfer switch. Backed by free 5-year warranties on each DELTA Pro.
