Battery Backup Installation in Kent, WA

Not every homeowner wants a fuel-burning generator running in the driveway during an outage. Washington Generators installs Tesla Powerwall and FranklinWH battery backup systems for Kent homes that want quiet, fuel-free backup power —either as a standalone system or paired with solar for a fully self-sufficient setup.

Battery vs. Generator — Different Tools for Different Needs

A battery system runs silently and produces no emissions, but it’s limited by stored capacity — it can run out during a multiday outage without solar to recharge it. A generator can run indefinitely as long as it has fuel, but it’s louder and requires fuel logistics. Many Kent homeowners end up choosing both, using the battery for quiet day-to-day backup and the generator as a longer-duration failsafe.

What’s Included in Battery Backup Installation

A proper battery backup installation covers system integration, not just mounting the unit:

• Site assessment and battery sizing for your home’s load
• Professional mounting and electrical integration
• Transfer switch and load prioritization setup
• Optional solar integration for ongoing recharge capability
• Compatibility planning if paired with an existing or new generator

Getting the Hybrid Setup Right

When a battery is paired with solar and a generator, the hardest part isn’t any single component — it’s making sure the transfer switch, load prioritization, and communication between all three systems actually work together. This is a specific area of expertise, and it’s where a lot of otherwise good installations run into trouble if the installer hasn’t done it before.
