Franklin - APBOX - for oversized PV systems & battery junction box
FranklinWH aPbox – Smart Solar System Management
The FranklinWH aPbox is an intelligent junction solution that enables remote and automated management of solar (PV) systems—especially when direct connection through the aGate X is not possible. Whether you're dealing with oversized solar arrays, remote PV locations, or complex system configurations, the aPbox ensures seamless integration and efficient control within the Franklin Home Power (FHP) architecture.
Key Benefits:
Remote & Flexible PV Integration Connect solar systems that are physically distant from the aGate X without the need for costly rewiring. Easily integrate existing or new systems into your FHP setup for centralized control and monitoring.
Smart Power Management The aPbox features built-in metering and current transformers (CTs) to monitor production and consumption in real time. It can automatically disconnect PV output during overproduction, off-grid scenarios, or when grid export limits are reached.
Protects Battery Health By intelligently managing excess solar generation, the aPbox prevents overcharging of the aPower X batteries—maximizing energy utilization while preserving system health.
Ideal for:
Remote Solar Systems: Simplifies connections when PV is installed far from aGate X
Oversized Systems: Manages additional PV beyond the 64A limit of the standard solar breaker
Over-Generating Systems: Prevents system shutdown by offloading excess generation
Product Highlights:
Flexible Configuration – Supports optimal PV energy distribution and usage
Simple Installation – Reduces labor and speeds up deployment
Easy Control – Automatically manages PV output during grid outages or system limits
