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
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.
