Tesla Powerwall Installation in Southern California

Powerwall stores your solar energy so you can use it after sunset instead of buying power back at peak rates. During outages, it automatically keeps critical circuits running – lights, fridge, internet, medical equipment – without you doing anything.

It works with new solar installs and with existing systems, and multiple Powerwalls can be stacked for larger homes or whole-home backup.

Under NEM 3.0, running Powerwall in self-consumption mode instead of exporting to the grid is usually the better financial move for most households, since export credits are worth a fraction of what they paid a few years ago. We help configure the Tesla app settings so the battery is actually optimized for your rate plan, not left on a generic default.

In most cases we can add Powerwall to an existing solar system without ripping anything out. We check your current inverter, electrical panel and layout and lay out exactly what's involved.

Some older inverter brands don't pair cleanly with Powerwall's gateway, in which case we'll tell you upfront whether an inverter swap is needed rather than discovering it mid-install.

Southern California's fire-season public safety power shutoffs and the occasional grid event make backup power a practical concern in the county's more exposed inland and canyon-adjacent neighborhoods, not just a nice-to-have. We configure Powerwall's backup gateway so the transition during an outage is automatic and seamless – no manual switching, no generator startup delay.

We'll also walk through realistic backup duration for your specific home given your loads, so you know whether one unit covers what you need or whether a second unit makes sense.
