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.
The DELTA Pro 3 doesn’t come with an MC4 to XT60i cable for connecting solar panels. This kit includes it, so you can plug in standard solar panels as soon as it arrives.
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.
