FranklinWH aPbox Empower Solar Expansion

The aPbox enables easy solar expansion by intelligently managing and controlling additional solar strings while protecting your energy storage system, optimizing solar energy usage, and preserving existing NEM contract rates.
Intelligently Managing Additional Solar Input

Intelligently Managing Additional Solar Input

A home energy management system has a solar power input limit to prevent solar overproduction that may otherwise damage the system.


The FranklinWH aPbox allows you to easily expand PV systems as your energy demand grows, by intelligently managing additional solar input from oversized systems. This means more solar generated power may be stored in aPower batteries, or exported to the grid to earn credits, boosting energy autonomy.

System Protection
against Overcharging

When generated power from your solar system exceeds the continuous power of aPower batteries plus the power demands of running loads, particularly common during outages or in off-grid situations where extra energy cannot be exported to the grid, the aPbox automatically disconnects the added solar systems to prevent overcharging and avoid the shutdown of your entire solar system.

PV Expansion without Losing Your Current NEM Benefits

PV Expansion without Losing Your Current NEM Benefits

Adding additional solar panels may result in your current PV systems losing NEM 1.0 or NEM 2.0 status. With an aPbox, you can install additional solar systems that produce more power to meet your growing household energy demands while only your existing PV systems send energy back to the grid under pre-existing net metering terms.

Facilitate Easier Solar Installation

Connect existing or new PV systems without altering power lines, saving installation time and reducing costs.


Works seamlessly with all inverter brands and integrates smoothly with your additional solar systems.
