What Is Battery Backup & Powerwall Installation?
Battery backup installation is the process of installing a home battery system — like the Tesla Powerwall — that stores electricity for use during an outage or during expensive peak-rate hours, wired into your home's electrical system through a dedicated Gateway or backup switch. Unlike a generator, a battery runs silently, needs no fuel, and can also actively save you money every day by charging during cheap off-peak hours and discharging during costly peak-rate periods. J&J Electric installs Tesla Powerwall and other home battery systems throughout Santa Rosa and Sonoma County under one C-10 license, #1078243, sized to what you actually want backed up.
Our Process
Here's what happens after you call (707) 480-8331:
- You tell us your goal. Outage protection, daily savings, or both — and whether you already have solar.
- We design around what you actually want backed up. Critical-loads only, or whole-home coverage requiring more capacity.
- You get a written, itemized estimate. Battery unit, Gateway/backup switch, labor, and permit costs broken down clearly.
- We pull the permit. Filed under our own license, with inspection scheduled and confirmed.
- We install and connect. The battery, Gateway, and any solar coupling wired in, matched to your home's actual electrical system.
- We test and walk you through it. Confirming backup function works as designed, and showing you how to monitor it.
How Much Does Battery Backup Installation Cost?
Battery backup cost depends mainly on how many battery units your home needs — a single unit sized for critical-loads backup costs less than a multi-unit system built for whole-home coverage — along with whether you're pairing it with existing or new solar. We give you a written, itemized estimate before any work starts.
Battery Backup vs. Whole-House Generator — Which Do You Need?
A battery runs silently, needs no fuel, and can save you money every day by shifting power use to cheaper off-peak hours — but it has a fixed, finite amount of stored energy. See our whole-house generator installation page → for the alternative.
A generator can run as long as fuel lasts, making it the stronger choice for extended multi-day outages, but it requires a fuel connection and runs with noise and exhaust.
Some homes genuinely benefit from both — a battery for quiet daily use and everyday savings, a generator as the backstop for longer outages. We'll walk you through which fits your situation, or whether both make sense.
Battery Backup & Powerwall Installation
What's Included — Battery Backup Services We Handle

Tesla Powerwall Installation
Including the required Gateway or backup switch, wired into your home's electrical system and, where applicable, coupled to existing or new solar.

Critical-Loads Backup Sizing
A smaller system covering the essentials — refrigeration, internet, lighting, a well or sump pump — for homeowners who don't need to back up everything.

Whole-Home Battery Backup
Multiple stacked battery units sized to cover your entire electrical panel, for homes that want complete coverage during an outage.

Grid-Charged Battery Backup (No Solar Required)
A battery can charge directly from the grid and still provide real backup power — solar isn't a requirement, just a common pairing.

Solar-Coupled Installation
For homes with existing or new solar, we connect the battery to store solar production for use later, including during peak-rate hours.

Panel-Related Work (When Needed)
Some installations involve panel work to properly integrate the battery system. See our electrical panel upgrades page →.

FAQ
Frequently Asked Questions
How much does battery backup installation cost?
It depends mainly on how many battery units your home needs. You get a written estimate before work begins.
Do I need solar panels for a home battery to work?
No — a battery can charge directly from the grid and still provide real backup power. Solar is a common pairing, not a requirement.
Battery backup vs. a whole-house generator — which is better?
A battery is quiet, needs no fuel, and can save you money daily by shifting power use to off-peak hours, but it has finite stored energy. A generator can run as long as fuel lasts, better suited to extended outages, but needs a fuel connection and runs with noise.
Will a battery power my whole house, or just some things?
It depends on how many units are installed. A single unit is often sized for critical-loads backup — the essentials. Whole-home coverage typically needs two or more stacked units.
Are there rebates available for installing a home battery in California?
California has an active incentive program for battery storage, and utility-specific rebates can also apply.
Does my installer need to be certified for this brand of battery?
Some manufacturers require certified installer status for current-generation products.
