Battery Backup & Home Energy Storage in Los Angeles

Tesla Powerwall vs. Enphase IQ Battery: which is right for your home?

Both are proven systems installed by HUS across Los Angeles and Orange County. The right choice depends on your existing solar setup, utility, backup goals, and electrical panel configuration.

Plan your battery upgrade.

Start with the solar system you already own. We review your inverter, utility, electrical layout and backup priorities before recommending a battery or deciding which equipment can stay.

Tell us your city, utility and inverter brand if known. Identify whether your solar is owned, leased or under a power-purchase agreement. You can start without every document; a recent bill and safely accessible equipment photos help the follow-up review.

Final compatibility, backup duration, utility treatment, price and installation timing depend on the project review and written scope.

Whole-home backup vs. essential-load backup.

If you are comparing battery storage with fuel-based standby backup, review our Tesla Powerwall vs whole-house generator comparison for runtime, noise, maintenance, fuel and solar-pairing tradeoffs. Tesla’s residential backup product is Powerwall battery storage, not a fuel-burning home generator.

Not every home needs to run every circuit during an outage. The choice between whole-home and essential-load backup shapes system size, cost, and electrical requirements.

How battery storage works with solar and NEM 3.0.

A battery changes how your solar system works — not just during an outage, but every day you generate more than you use.

• →Store excess solar instead of exporting it. When your panels produce more than your home uses, excess energy charges the battery instead of being sent to the grid — available for evenings, cloudy days, or outages.
• →NEM 3.0 applies to SCE, PG&E, and SDG&E — not LADWP. Net Billing (NEM 3.0) reduces export credit rates for customers of Southern California Edison and other IOUs, making battery self-consumption a stronger economic strategy for SCE solar customers. LADWP and Burbank Water & Power customers are on their own net-metering programs — not NEM 3.0 — which we review specifically for LADWP-territory homes.
• →Time-of-use rate management. Under SCE time-of-use plans, electricity costs more during evening peak hours. A battery charged by solar during the day can offset peak-rate draw — the economic value depends on your specific rate plan, usage, and system configuration.
• →Solar-charged backup. With the right inverter and system configuration, your solar panels can continue charging your battery during a grid outage, extending backup without relying solely on stored energy. Configuration requirements vary by inverter type and system design.

LADWP vs. SCE battery planning.

Your utility is the single most important factor in battery planning — it determines export rates, available rebate programs, and interconnection rules.

Current SGIP battery incentive status.

SGIP uses multiple battery and solar-plus-storage budget categories administered separately across California. Current open, closed, waitlist and available-funding status can differ by category and territory, so check the live SGIP Program Metrics before estimating an incentive.

• →No general-market rebate. Do not subtract SGIP from an advertised battery price or proposal unless the program administrator has formally approved and reserved the incentive.
• →Income-qualified pathways. Residential Solar and Storage Equity and other equity categories have additional customer, utility, equipment and documentation requirements. Confirm the current category status and eligibility with the applicable program administrator.
• →Funding is not guaranteed. A submitted or waitlisted application is not the same as reserved funding.
• →Verify current status. Review selfgenca.com and the applicable utility administrator before signing a contract based on incentive assumptions.

Home Upgrade Specialist can review installation feasibility and documentation, but final eligibility and funding approval remain with the SGIP program administrator. Current SGIP status guide →

Backup load panel & Gateway overview.

The right electrical configuration is what makes battery backup actually work when the grid goes down. Here is what to know before your estimate.

• →Backup load panel (critical load sub-panel). For essential-load backup, a dedicated sub-panel separates your backed-up circuits from the rest of the home. During an outage, battery power flows only to those circuits. We specify sub-panel sizing and circuit selection based on your backup goals and existing electrical.
• →Tesla control architecture. Depending on the approved design, a Powerwall installation may use Backup Gateway 2, Gateway 3 or a utility-approved Backup Switch. This equipment isolates the backed-up system from the grid, manages solar and battery operation, and communicates with the Tesla app.
• →Automatic outage transition. A properly commissioned system transfers automatically after a grid outage. Actual transition behavior depends on the approved equipment, firmware, electrical design and connected loads, so proposals should not promise an exact transfer time unless supported by the selected product documentation.
• →Panel capacity and electrical upgrades. Some homes need a panel upgrade, load-management strategy, or additional breaker space to accommodate battery equipment. We assess the visible electrical conditions during project planning and identify known required electrical work in the written scope. Concealed conditions, utility requirements, field discoveries, or agency corrections can still affect final scope.

Prepare your backup-load checklist.

A useful battery estimate starts with the circuits and outage goals, not with a battery count. Bring the following information so the design can be screened against actual loads and electrical conditions.

• →Recent utility bill and service address to confirm LADWP, SCE or another municipal utility.
• →Electrical-panel and meter photos, including breaker ratings, available spaces and any existing solar equipment.
• →Priority outage loads, such as refrigeration, lighting, internet, medical equipment, gates, sump pumps or selected HVAC circuits.
• →Large loads to manage or exclude, including EV charging, electric ranges, pool equipment, central air conditioning and heat pumps.
• →Future plans for solar, an EV, electrification, an ADU or a panel upgrade that could change system sizing.

Solar, roofing & battery together.

Many home battery projects are paired with solar, and roof condition can affect solar timing. If you are planning roof, solar, battery and HVAC work together, review our Los Angeles solar, battery, HVAC and roofing integration guide so the loads, roof timing and electrical scope are evaluated together. Home Upgrade Specialist can coordinate scope, sequencing, trade responsibility, permit paths, utility steps and warranty documentation to reduce avoidable rework where project conditions allow it.
