FranklinWH 15 kWh Whole Home Battery System
The FranklinWH 15 kWh whole home battery system is a high capacity residential energy storage solution built for extended backup power, intelligent energy management, and long term energy resilience. With increased storage capacity compared to smaller batteries, this system is designed to support modern homes with higher electrical demand and longer outage protection needs.
The 15 kilowatt hour capacity makes this battery well suited for whole home backup configurations, especially for homes with larger loads, electrified appliances, or multiple backup priorities.
Whole Home Backup Power
The FranklinWH 15 kWh battery is designed to support whole home or expanded load backup rather than limited critical circuits. When a power outage occurs, the system transitions automatically to battery power, helping maintain normal home operation without interruption.
This silent, fuel free backup solution provides a dependable alternative to traditional generators while offering instant response during grid disruptions.
Solar and Generator Integration
The FranklinWH 15 kWh battery is compatible with solar energy systems, allowing stored energy to be replenished through on site solar production. In addition to solar charging, the system also supports generator integration for extended outage scenarios.
A portable or roll away generator rated at a minimum of 7 kW can be used to recharge the battery when solar production is unavailable or insufficient. This hybrid setup allows homeowners to extend backup duration while reducing generator runtime and fuel consumption.
Scalable Energy Storage Design
As household energy needs grow due to electrification upgrades, electric vehicle charging, or future expansion, additional battery units can be added to increase total storage capacity. This modular design supports long term planning without requiring a full system replacement.
Warranty and Long Term Reliability
The FranklinWH 15 kWh battery is backed by a 10 year manufacturer warranty, providing long term coverage and confidence in system performance. The warranty is designed to support daily energy use, backup operation, and long term reliability, making the system a durable investment in home energy infrastructure.
Built for Energy Independence
By combining high capacity battery storage, intelligent energy control, and flexible charging options, the FranklinWH 15 kWh battery supports homeowners who want greater independence from the utility grid. Whether used for outage protection, energy optimization, or preparedness planning, this system provides a strong foundation for a resilient home energy strategy.
