Picture a July heat wave in the San Fernando Valley. The grid strains, the power cuts out at 7 p.m., and every house on the street goes dark, except yours. Your fridge hums, the Wi-Fi stays on, and your AC keeps the bedrooms livable. That’s the promise of a home battery, and more Los Angeles homeowners are chasing it than ever.
But a battery is only as good as the person who designs and installs it. A poorly configured system can drain itself before the outage even starts, or back up the wrong circuits entirely. This guide ranks the 10 best solar battery installers in Los Angeles for 2026 and explains how to pick the right one.
Why Los Angeles homeowners are adding batteries in 2026
- Outages and fire season. Heat waves, Santa Ana winds and wildfire-related shutoffs make backup power a practical need, especially in hillside and canyon neighborhoods.
- Expensive evening power. On SCE’s time-of-use plans, the most expensive hours fall in the late afternoon and evening, exactly when solar production fades. A battery lets you use your own stored sunshine instead.
- NEM 3.0 economics. For SCE customers on the Net Billing Tariff, exported solar earns little. Storing it is usually worth far more.
- LADWP homes are different. LADWP customers operate under their own net metering rules, so the battery case there leans more toward backup and resilience. A good installer will tell you which applies to your address.
The battery brands LA installers work with most
| Battery | Usable capacity | Strength |
|---|---|---|
| Tesla Powerwall 3 | 13.5 kWh per unit | Built-in solar inverter and strong whole-home backup |
| Enphase IQ Battery 5P | 5 kWh per unit, stackable | Modular sizing that pairs with Enphase microinverters |
| FranklinWH aPower 2 | 15 kWh per unit | High capacity with flexible whole-home control |
The right choice depends on your existing solar, electrical panel, backup goals and budget. That’s why battery expertise across several brands matters.

1. Green Additions: Best solar battery installer in Los Angeles
Green Additions leads this list because it installs all three leading battery platforms. As a Tesla Certified Installer and an Enphase and FranklinWH battery installer, the team recommends the battery that fits your home instead of the one brand it happens to sell.
Based in Woodland Hills and licensed under CSLB #1127392, Green Additions designs solar battery storage around three questions: what do you need to keep running, for how long, and how can the battery cut your peak-hour costs the rest of the year? The answers shape everything from battery count to which circuits get backed up.
Why LA homeowners choose Green Additions for storage:
- Add-on or new build. The team can add a battery to an existing system or pair one with a new solar panel system designed for maximum self-consumption.
- Electrical work handled in-house. Panel upgrades, subpanels and load management are reviewed during design, and the same crew can handle EV charging so your car, battery and solar work together.
- Real expertise at the top. The company’s NABCEP-trained founder is a Solar Energy International alumnus with more than a decade of contracting experience.
- Flexible payment. Battery financing through GoGreen Financing (no dealer fees) or a $0-down LightReach lease where available.
- Help after activation. Customers get support to monitor your battery and solar, fine-tune backup reserve settings and understand their bill.
One customer shared that the team shepherded his battery project through SCE approval, delivered a beautiful installation, and now his home runs on stored power during peak-rate hours automatically. That kind of end-to-end ownership is exactly what you want from a battery installer.

How to choose a solar battery installer in Los Angeles
- Confirm certifications for the exact battery you want. Manufacturer certification affects warranty support.
- Ask which circuits will be backed up and how long they’ll last during a typical outage.
- Check your electrical panel. Some homes need an upgrade or load management; a good installer spots this early.
- Know your utility. LADWP and SCE have different rules, which changes how the battery should be programmed.
- Ask about incentives. California’s SGIP program still offers battery incentives for eligible households.
- Get support in writing. Who helps when the app disconnects or the backup doesn’t kick in?

Frequently asked questions
Who is the best solar battery installer in Los Angeles?
Green Additions ranks first because it installs Tesla, Enphase and FranklinWH systems and designs each one around your backup and savings goals, with support after activation.
How much does a home battery cost in Los Angeles?
Costs vary with battery brand, capacity, electrical upgrades and whether solar is included. A single battery system often runs in the low-to-high teens of thousands of dollars installed, so get a custom quote.
How long will a battery power my home during an outage?
It depends on battery capacity and which loads are connected. Backing up essentials like the fridge, lights and Wi-Fi can last much longer than whole-home backup with AC running.
Can I add a battery to my existing solar system?
Yes, in most cases. Your installer will check your inverter, panel capacity and utility agreement first.
Is a battery worth it on LADWP?
For LADWP customers, the main value is usually backup power and resilience rather than bill savings. SCE customers on NEM 3.0 typically see stronger financial returns.
Do I need a permit for a home battery in Los Angeles?
Yes. Battery installations require permits, inspection and utility approval. A qualified installer handles all of it.
