Tesla Powerwall 3 · Premier Certified · Los Angeles County
OC Solar is a Tesla Powerwall Premier Certified installer serving all of Los Angeles County. We engineer and install Powerwall 3 systems that crush SCE 4–9 PM NEM 3.0 peak rates, optimize LADWP Time-of-Use bills, and keep your home powered through canyon PSPS shutoffs and grid outages.
LADWP vs. SCE Battery Economics
Los Angeles County splits between Southern California Edison (CPUC NEM 3.0) and municipal utilities led by LADWP. Here is how we program and size Tesla Powerwall 3 for each grid.
In Long Beach, Torrance, Santa Clarita, Whittier, Calabasas, and 70+ SCE cities, midday solar exports earn pennies while 4–9 PM TOU-D-PRIME peak power averages ~$0.36/kWh (and spikes higher in summer). Powerwall 3 banks your midday solar and discharges from 4–9 PM so you avoid buying peak SCE power. See SCE solar + battery math →
LADWP (City of LA) as well as Pasadena (PWP), Glendale (GWP), and Burbank (BWP) are exempt from CPUC NEM 3.0 and run independent solar rules. On LADWP's R-1B TOU schedule (High Peak 1–5 PM, Low Peak 5–8 PM) or Burbank's 2026 Net Billing tariff, Powerwall 3 shifts solar into afternoon/evening AC hours and locks in whole-home backup. See LADWP guide →
From Santa Ana wind PSPS shutoffs in Malibu, Calabasas, Altadena, La Cañada Flintridge, and Santa Clarita to summer transformer overloads across the San Fernando Valley and Westside, Powerwall 3 switches over in milliseconds and recharges from your rooftop solar each morning.

Powerwall 3 at a glance
Tesla's Powerwall 3 combines a high-output 11.5 kW inverter and 13.5 kWh LFP battery in one thermal-managed enclosure. Here are the verified specs that matter for Los Angeles homes.
13.5 kWh usable
Usable LFP storage per Powerwall 3 — enough to shift evening air-conditioning and home loads off the grid, and stackable up to 4 units (54 kWh).
11.5 kW continuous
Continuous power output with 185 A LRA motor-start capability, so a single unit can start heavy AC compressors and run real home loads during an outage.
Native solar + AC retrofit
Powerwall 3 includes a built-in 6-MPPT solar inverter for new systems and AC-couples cleanly with existing Enphase, SolarEdge, or string solar arrays.
~10-year warranty
Backed by Tesla's manufacturer warranty and OC Solar's in-house C-10 electrical workmanship coverage.

Why OC Solar in Los Angeles
Battery projects in Los Angeles stall when installers don't know local fire setbacks, LADBS plan check, or LADWP metering rules. Our in-house engineering and permitting teams file in these jurisdictions every week.
We hold Tesla's top installer certification and sit on the Tesla Pro Council (1 of 12 installers nationwide). ConsumerAffairs also names OC Solar Best overall in its Los Angeles solar guide.
No subcontractor handoffs. Our own licensed crews handle the engineering, electrical work, and wall mounting across Los Angeles County.
We manage LADBS, EPIC-LA, SolarAPP+, and municipal building permits plus LADWP, SCE, PWP, GWP, and BWP interconnection end-to-end.
We prepare UL 9540A fire-safety clearances, site plans, and electrical single-line diagrams for LADBS (City of Los Angeles), LA County Building & Safety (EPIC-LA), SolarAPP+ express cities, and independent building departments across LA County:

The process
Every OC Solar Powerwall installation is turnkey: our own crews design the system, pull the city or county permit, install and integrate the battery, meet the inspector, and file the LADWP or SCE interconnection until you have Permission to Operate.
We inspect your main electrical panel, wall clearances, fire-setback requirements, and LADWP or SCE tariff, then provide an itemized quote — with cash, loan, and §48E Prepaid/Lease options side by side.
Whether your home permits through LADBS, LA County EPIC-LA, SolarAPP+, or an independent city counter from Pasadena to Torrance, our team files the plans and tracks approval.
Our own licensed technicians mount the Powerwall 3, install the Backup Switch or Gateway, and complete clean conduit work — typically in one to two days on site.
We meet the building inspector, resolve any AHJ plan-check notes, and push your LADWP, SCE, or municipal utility interconnection application through to Permission to Operate (PTO).
We commission the battery and configure Time-Based Control (4–9 PM SCE peak or LADWP R-1B peak windows) and Storm Watch backup reserves in your Tesla app.
Inspection and Permission to Operate queues are controlled by your AHJ and utility — we own the paperwork end-to-end and keep you updated weekly. See our full 5-step installation process.

Los Angeles Powerwall FAQ
Everything from engineering to Permission to Operate: a site review and firm line-item quote, AHJ permitting (LADBS in the City of Los Angeles, EPIC-LA in unincorporated LA County, or your city's building department), installation and electrical work by our own in-house crews, the city/county inspection, and utility interconnection with LADWP, Southern California Edison (SCE), or your municipal utility. We activate the system, configure time-of-use and backup controls in the Tesla app, and back the work with our in-house workmanship coverage alongside Tesla's roughly 10-year Powerwall 3 warranty.
OC Solar's Tesla Powerwall 3 installation range is $9,995–$15,995, as of September 2026. $9,995 is for a basic installation with Participate Energy. Final pricing depends on your home's custom configuration and the selected plan. Garage or outdoor placement, distance to the main service panel, whole-home or partial backup, and a Backup Switch or Gateway all affect the installation scope.
In SCE territory (Long Beach, Torrance, Santa Clarita, Whittier, Calabasas, and most suburban LA County cities), CPUC NEM 3.0 cut daytime solar export credits by roughly 75%, making a Powerwall 3 essential for storing midday solar and discharging during SCE's expensive 4–9 PM TOU peak (~$0.36/kWh average). In the City of Los Angeles, LADWP is a municipal utility outside CPUC NEM 3.0 jurisdiction with its own R-1A standard and R-1B Time-of-Use High Peak (1–5 PM) / Low Peak (10 AM–1 PM & 5–8 PM) windows — where a Powerwall 3 delivers whole-home outage backup, late-afternoon AC peak shaving, and grid independence.
Permitting in Los Angeles County is fragmented across 88 cities plus unincorporated territory. Our in-house permitting team submits directly through LADBS for City of Los Angeles addresses, LA County Building & Safety's EPIC-LA portal for unincorporated communities and contract cities, and automated SolarAPP+ / Symbium portals in participating cities like Santa Monica, Culver City, Calabasas, Downey, and Covina — as well as municipal utilities in Pasadena (PWP), Glendale (GWP), and Burbank (BWP).
Yes — retrofitting a Tesla Powerwall 3 onto an existing solar array is one of our most frequent Los Angeles County projects. Each Powerwall 3 provides 13.5 kWh of usable LFP storage and 11.5 kW of continuous power (stackable up to 4 units / 54 kWh). We verify your existing inverter, main service panel, wall clearance, and LADWP or SCE interconnection agreement before engineering the addition.
The residential federal clean energy credit (IRC §25D) expired on December 31, 2025, so homeowner cash or loan purchases no longer receive a personal federal tax credit. However, on third-party owned $0-down Leases, PPAs, or Prepaid Solar + Storage plans, the commercial financier claims the §48E commercial tax credit and passes roughly 30% of the system value through in your pricing. General-market SGIP battery rebates are largely exhausted, though limited income-qualified Equity Resiliency tracks remain open for eligible households; we never pad quotes with unverified rebates.
