The DELTA Pro Ultra X is EcoFlow's whole-home backup system, built around a wheeled inverter unit and two batteries. A single inverter delivers strong continuous output, and three inverters run in parallel to reach 36 kW continuous and 45 kW peak, enough for a large house with central air and an EV charger. It accepts solar input up to 500 V and connects over Wi-Fi for app control, scheduling and third-party integration. It suits owners who want a permanent, expandable home power system rather than a portable camping battery, and it competes with fixed home-standby generators and other whole-home battery systems on quiet, fume-free operation and modular expansion.

Ratings are very high, and owners describe the system as a serious whole-home backup solution that runs quietly and handles heavy loads. Praise centers on output, build and app control; criticism is mostly about weight and the cost of scaling to full power.
