Benefits of a FranklinWH battery installation include:

Backup power during utility outages
Solar energy storage for evening, overnight, or cloudy-day use
Reduced reliance on the utility grid
Better energy management during peak utility-rate periods
Support for clean, renewable energy goals
Smart energy control through the FranklinWH aGate
Integration options for solar, battery, grid, and generator power

Generator Integration: Battery Backup Plus Standby Power

Washington Generators has deep experience installing Generac and Kohler standby generators, which makes FranklinWH a natural fit for homeowners who want both battery storage and long-duration backup power.

A home battery can provide quiet, instant backup power during an outage. A standby generator can provide extended backup during longer outages. When designed correctly, the combination of FranklinWH battery storage and generator integration can create a highly resilient home power system.

This is especially valuable in Western Washington, where storms, wind events, grid interruptions, and extended outages can leave homeowners looking for more than a short-term backup solution.

The FranklinWH aGate can help manage power from the grid, solar, battery storage, and compatible standby generators — including Generac and Kohler systems. FranklinWH also publishes generator integration guidance and recommended generator sizing practices for its home power system.

What Homeowners Should Know Before Adding a Battery

Every home is different. The right FranklinWH system depends on your electrical panel, utility service, solar setup, backup-power goals, and whether you want to integrate a standby generator.

Before installation, consider:

Which circuits or appliances need backup power
Whether the system will be paired with solar panels
Whether a generator will be integrated for extended outages
Available installation space
Utility and permitting requirements
Future expansion needs
Whole-home backup versus essential-load backup

Washington Generators can help evaluate your home and recommend a FranklinWH system designed around your actual power needs.
