Generator integration
FranklinWH stands out with its seamless generator integration—a capability not currently offered by Tesla’s Powerwall 3. With the FranklinWH aGate and Generator Module, your system can intelligently manage multiple power sources, including your generator, solar, battery, and the utility grid.
The system automatically prioritizes clean energy, but when extended outages occur, your generator steps in without a hitch. Through the FranklinWH app, you can even schedule generator usage to preserve fuel and extend backup duration. This smart orchestration ensures your home stays powered—no matter what.
