The FranklinWH Backup Expansion Lug Kit is an optional accessory designed to expand the backup and energy storage capabilities of the Franklin Home Power (FHP) system. Engineered for use with the FranklinWH aGate and aPower battery system, this expansion lug kit enables installers to connect additional aPower batteries or distribute backup loads across multiple sub-panels for larger residential energy storage installations. When systems require four or more aPower batteries, the Backup Expansion Lug Kit provides the necessary connection interface to safely integrate expanded battery capacity through the backup port. The kit also supports dual sub-panel configurations, improving flexibility for whole-home or partial-home backup applications. Rated for 120/208V and 120/240V split-phase systems with up to 160A continuous current, the compact lug kit is ideal for advanced solar + storage installations requiring scalable backup infrastructure.
