Components

FranklinWH system integrates multiple energy sources to provide a comprehensive home energy management and backup solution. It stores energy from solar, grid, and generators for self-consumption, load shifting under TOU rates, or backup during outages. The FranklinWH system intelligently monitors and manages your home energy, helping you optimize usage. With automatic upgrades, you’ll always enjoy the latest features and best user experience.

The FranklinWH system consists of three essential parts: aGate, aPower, and the FranklinWH App. The aGate serves as the intelligent energy management center, controlling the entire system. The aPower provides battery storage with a built-in inverter. Customers can remotely monitor their home energy status and control the FranklinWH system via the app.

 

aGate

As the intelligent home energy management center, the aGate integrates solar, grid, battery storage, and generator to provide users with energy independence. During a power outage, the aGate automatically switches to available energy sources to ensure uninterrupted power. Additionally, the aGate can individually manage multiple critical household loads, enhancing energy efficiency and safety.
