About This Product
The FranklinWH aHub 24kW Energy Management Expansion Unit is a system expansion unit for the FranklinWH home energy platform. Manufacturer part number ACCY-AHUBV1-US, the aHub works with a FranklinWH aGate or Meter Adapter Controller to integrate additional energy sources and controllable household loads into one managed system. It can accommodate AC-coupled solar, generator, vehicle-to-load (V2L), and Smart Circuit connections, giving installers additional flexibility when designing or expanding a FranklinWH solar and storage installation.

Who This Product Suits
The FranklinWH aHub suits residential FranklinWH installations that require more energy-source or load-management connections than the primary system controller provides. It is particularly useful for solar retrofits, systems with multiple AC-coupled PV arrays, generator integration, compatible V2L-capable vehicles, and projects requiring additional Smart Circuits. It is intended to be incorporated into a properly engineered FranklinWH system by a qualified installer in accordance with manufacturer requirements and applicable NEC and local electrical codes.
Specifications Explained
- 24 kW AC-coupled PV capacity: Supports up to three AC-coupled PV arrays with a combined capacity of up to 24 kW.
- US residential electrical systems: Supports 120/208 Vac and 120/240 Vac, 60 Hz applications.
- Four configurable ports: Connections can be assigned for Smart Circuits, PV, and, on the applicable port, generator or V2L integration.
- Smart Circuit management: Supports configurations of up to four 240 V Smart Circuits or eight 120 V circuits for programmable load control.
- 100 A main-port continuous current: Provides substantial capacity for integration into compatible FranklinWH system designs, with upstream overcurrent protection rated up to 125 A.
- Generator and V2L support: Allows compatible 240 V generator and vehicle-to-load sources to be incorporated where the system configuration supports them.
- CAN and RS485 communications: Provides system communications, including RS485 support for applicable long-distance solar configurations.
- FranklinWH App integration: Connected resources and Smart Circuits can be managed as part of the FranklinWH energy management platform.
Summary
The FranklinWH aHub is an expansion component for installers building more capable FranklinWH energy systems. With support for up to 24 kW of AC-coupled PV, configurable Smart Circuits, generator and V2L integration, and centralized management through the FranklinWH platform, it provides a practical way to add energy sources and controllable loads without treating each function as a separate standalone system.
