Description
Overview
The EcoFlow DELTA Pro 3 is a 4,096Wh LFP power station with 4,000W of output at both 120V and 240V. X-Boost lets it run devices up to 6,000W, and it keeps delivering 4,000W while it charges. Capacity expands from 4kWh to 48kWh with extra batteries.
It charges from 0 to 80% in 50 minutes, and combined charging methods reach up to 7,000W. Two units in parallel deliver up to 12,000W. Wide wheels, an ergonomic handle and magnetic sliding doors make it easy to move around the house.
Connect it to your home three ways: the Smart Home Panel 2 (up to three units, 12 circuits, 20 ms switchover), an inlet box using the built-in NEMA L14-30R outlet, or a manual transfer switch. Note that the DELTA Pro 3 is not compatible with the original DELTA Pro or DELTA Pro Ultra accessories.
