The Core of Your Long-Term Energy Strategy
Two Future-Proof Energy Hubs
Two smart panel options power your whole-home system: Smart Home Panel 3 for circuit-level precision, or Smart Gateway for seamless backup. Both integrate solar, generators, and EV charging, with <20 ms switchover10.
- Smart Home Panel 3
- Smart Gateway
Precision Power Control
Connect essentials, track and control usage circuit by circuit, and fine-tune in real time. Prioritize your heat pump, throttle non-essentials, or monitor individual appliances.
Set-and-Forget Simplicity
Built for homeowners who don’t want to micromanage. During outages, Gateway switches in <20 ms and auto-sheds non-essentials so fridges, lights, medical devices, and Wi-Fi run longer. Set essentials once—no need for updates or fine-tuning.

Your 24/7 Money Saver
Here's a Typical Day of Savings
Day and night, the system intelligently shifts between solar, storage, and off-peak rates—maximizing every watt to get you the best deal. Here's what that might look like on a typical day of use.
Midnight – 9 AM: AI-TOU Savings
The system uses TOU electricity rates and solar forecasting to intelligently optimize charge times and save you money.
9 AM – 5 PM: Self-Powered & Automated Savings
Solar will run your appliances and charge the system batteries. Timed Circuit Control11—Schedule up to all the circuits to turn on or off automatically—so you only use energy where it’s needed.
5 PM – Midnight: Solar at Work
Uses stored solar to run your entire home. Plug your EcoFlow PowerPulse EV charger directly into Smart Home Panel 3 or Smart Gateway to save even more.
Compatible with Existing Rooftop Solar12
No Wasted Watts
With the EcoFlow Current Sense Transformer, every extra watt is redirected to your DELTA Pro Ultra X battery—never wasted or sold back to the grid for pennies.
