King Electric and Solar handles the full Powerwall project, from reviewing your electrical panel and solar array to installation, commissioning, and PG&E interconnection paperwork. We're a local electrical contractor working throughout Auburn and the surrounding foothill communities, and we design each system around real load data rather than a generic template.
Powerwall gives you quiet, automatic backup power along with more control over how and when you use stored energy.
Instant, silent switchover during outages
Whole-home or essential-load backup configurations
Stores solar or off-peak energy for peak rates
Tesla app monitoring of usage and backup status
Retrofits onto existing solar, any brand or inverter
Backup gateway manages safe grid isolation automatically

Guys showed up on time and were professional in appearance. They replaced my 200W panel and did a great job in doing so. We are satisfied with the work they accomplished.

Every Powerwall project starts with an honest look at your home's electrical setup before any equipment is ordered.
We inspect your existing electrical panel and, if applicable, your current solar array. An outdated panel or underperforming solar system gets addressed before Powerwall installation moves forward.
We walk through which circuits matter most during an outage, from refrigeration to lighting, and calculate how many Powerwall units your home actually needs to meet those priorities.
We prepare and submit the required permits and handle PG&E interconnection paperwork, so the system is approved and compliant before it goes live.
Our electricians install the Powerwall and backup gateway, wire it to your panel and solar system, and commission it so it's registered and communicating properly with the Tesla app.
Before we leave, we test outage switchover and walk you through monitoring your system, backup settings, and energy usage through the app.
Get clear answers about tesla powerwall installation, preparation, timing, maintenance, and what to expect before requesting an estimate.
Q1
Yes. We handle the full process, including installation, commissioning, and system registration, along with the electrical work, permitting, and PG&E interconnection required to bring a Powerwall online.
Q2
It depends on your circuit priorities and startup loads. Homes with air conditioning or well pumps often need more capacity. We calculate this during a load assessment rather than guessing upfront.
Q3
In most cases, yes. Powerwall can retrofit onto existing solar arrays regardless of brand or inverter type. We first check that your current system is performing well enough to pair with battery storage.
Q4
That depends on your home's loads and how many Powerwalls are installed. Some homes run whole-home backup, others use an essential-load plan focused on key circuits. We confirm this during system design, not after installation.
Q5
Yes. We prepare the permit submissions and manage the PG&E interconnection process as part of the installation, so the system is properly approved before it's put into service.
Q6
Yes. Beyond outage backup, Powerwall stores solar or lower-cost energy and can use it during peak utility rate periods, giving you more control over daily energy use in addition to backup protection.
Q7
It depends on your outage needs. Powerwall offers quiet, instant backup for typical outages, while a standby generator suits multi-day outages or heavy loads. Some foothill homes benefit from having both.
Q8
They can be. High startup loads sometimes require multiple Powerwalls or an essential-load approach rather than whole-home backup. We review this during sizing so expectations match what the system can actually support.
