EcoFlow Smart Gateway (200A) — Effortless Whole-Home Backup with 6 Smart Circuits and 20ms Auto-Switchover
The Smart Gateway is EcoFlow's streamlined whole-home backup solution — a 200A intelligent transfer switch that connects DELTA Pro Ultra X to your home's existing electrical panel without replacing it. It automatically controls 6 priority circuits, switches from grid to battery in under 20ms, and manages energy from solar panels, generators, and EV chargers through a single app.
⚠ Professional Installation Required. The Smart Gateway must be installed by a licensed electrician. Installation fees are assessed on-site and are not included in the product price. A temporary power outage at your home will occur during installation.
⚠ Rooftop Solar Requires Current Transformers. Connecting rooftop solar panels through the Smart Gateway requires current transformers, which are not included and must be purchased separately.
⚠ 6 Circuits Only — Not a Full Panel Replacement. The Smart Gateway controls 6 priority circuits from your existing panel. For whole-home control across 32 independently managed circuits, see the EcoFlow Smart Home Panel 3.
⚠ Shipping Restriction. Cannot be shipped to Alaska, Hawaii, Puerto Rico, or other US outlying territories.
Key Features
