Citrus Heights home-base installs: home battery backup in Citrus Heights.

    What a battery does on a SMUD outage day

    Sacramento outages are usually short, but summer heat events and winter storms can take power out for hours. A home battery keeps the circuits you pick running: fridge, lights, Wi-Fi, a few outlets, sometimes the whole house. Under the Sun Solar & Electric (CSLB #1141678, C-10) installs the battery and does the electrical work around it in one job.

    Battery backup installation in Sacramento

    Most of a battery install is electrical: the panel has to have room, the backup loads get moved to their own panel or the gateway handles the switchover, and SMUD has to approve the interconnection before the system runs in parallel with the grid. That is the part we do every week.

    Whole-home or critical loads

    A critical-loads setup moves the circuits you choose to a backup subpanel. A whole-home setup backs up the main panel, which often means a panel upgrade first. We look at your panel and your bills before we recommend either. If the panel is the problem, see panel upgrades in Sacramento.

    With solar or without

    A battery can charge from existing solar or from the grid. Without solar it is backup only. With solar it can also cover evening use. If you already have panels, we check the inverter and the interconnection agreement first so the battery does not break anything that already works.

    Tesla Powerwall installs

    We install Tesla Powerwall, including Powerwall 3, and can talk through other batteries on the consult. Tell us what you have been quoted and we will tell you what the electrical side involves.

    SMUD battery program

    SMUD runs an incentive for customer batteries. The amount is per kWh of capacity with a cap, and it changed for interconnections submitted on or after September 23, 2026. We check current SMUD terms for your address before we quote and file the paperwork with the interconnection. Roseville Electric and PG&E customers have different programs; ask and we will check yours. For the California SGIP side, see our SGIP rebate guide.

    How the job goes

    1. Site visit: panel, main breaker, where the battery and gateway can mount, which loads matter.
    2. Written quote and a one-line diagram for permit.
    3. Permit and SMUD interconnection application.
    4. Install, usually one to two days, then inspection.
    5. Permission to operate from the utility, then we turn it on and walk you through the app.

    No. Without solar it charges from the grid and works as backup. With solar it can also store daytime production.

    It depends on battery size and what is on the backup panel. Fridge, lights and Wi-Fi go a long way; central AC drains it fast. We size it from your actual usage.

    Sometimes. Whole-home backup on an older 100-amp panel often needs one. Critical-loads setups often do not.

    We do. We submit the interconnection and check the current SMUD battery incentive terms for your install.
