Description
The ultimate home backup bundle for DELTA 2 Max owners — the EcoFlow DELTA 2 Max + Extra Battery + Transfer Switch brings together everything you need for automated, whole-home circuit backup in a single purchase. Instead of piecing together components separately, this bundle gives you expanded storage, doubled capacity, and the critical transfer switch needed for hands-free automatic failover when the grid goes down.
The EcoFlow DELTA 2 Max starts with 2,048Wh of LiFePO4 capacity and delivers 2,400W of continuous AC output (5,000W X-Boost). The bundled Smart Extra Battery adds another 2,048Wh, bringing total storage to 4,096Wh — enough to power a family home’s essential circuits for 12 to 24+ hours depending on consumption. The DELTA 2 Max charges from 0 to 80% via AC in approximately 1.8 hours and supports up to 1,000W of solar input, so you can recharge rapidly from the grid or from the sun.
The included EcoFlow Transfer Switch is what transforms this from a portable power station into a true home backup system. The transfer switch connects between your home’s electrical panel and the DELTA 2 Max, detecting grid failure and automatically switching selected circuits to battery power — with no manual intervention, no extension cords, and no fumbling in the dark. Selected circuits continue running without interruption the moment the grid fails.
Professional installation is required for the transfer switch. Compatible with the EcoFlow app for real-time energy monitoring, smart scheduling, and remote management. Backed by a free 5-year warranty on the DELTA 2 Max.
