Tesla Powerwall installation by a certified installer
Cali Energy is a Tesla Powerwall Certified Installer based in Northridge. We install Powerwall across Los Angeles and the San Fernando Valley, in Burbank, Glendale, Calabasas, Simi Valley and Santa Clarita, with new solar or beside a system you already have, and carry it through the city permit and the utility's storage approval.
A Powerwall 3 stores 13.5 kWh. Making it work for your house means deciding what it backs up, mounting it where the fire code and Tesla's manual allow, wiring it into your main panel, and getting the utility's storage approval after the city's final inspection. Cali Energy installs Powerwall across Los Angeles and the San Fernando Valley as a Tesla Powerwall Certified Installer; in San Fernando a Powerwall went in with a 22-module Enphase array, joined it on the AC side and now stores the afternoon's solar for the evening.
Powerwall with new solar or beside an existing system
- With new solar, the Powerwall is designed into the system from the first drawing: what it backs up, where it hangs, and how it connects to the main panel. In San Fernando the Powerwall bracket went on the patio wall before the 22-module Enphase array went on the roof, and the battery joined the microinverters on the AC side.
- Beside a system you already have, the Powerwall goes in as its own project, with its own permit and the utility's storage approval.
What it backs up
One Powerwall 3 holds 13.5 kWh. The continuous output decides which circuits it can carry at once, and we set the backup around it: either the whole house, or the circuits that matter on a backup panel. Whole home or the circuits that matter
How a Powerwall installation runs
- Site visit. Main panel, meter, the wall for the Powerwall, and the circuits you want running in an outage.
- Design. Number of Powerwalls, backup scope, and placement with clearances drawn on the plans.
- Permit with LADBS or your city, and plan check answered.
- Installation under our C-10 electrical license. In San Fernando the bracket went up first thing in the morning, and the Powerwall and array were in place the next morning.
- Inspection and utility approval. After the city's final, the utility approves the storage on its own track.
- Commissioning. Backup reserve set, the Tesla app connected, and a walk-through of what runs when the grid goes down.
