Battery storage went from optional to essential between 2023 and 2026. With the CPUC's NEM 3.0 Net Billing Tariff in full effect across California's IOUs - and LADWP running its own evolving net-metering program - batteries are what make residential solar pencil today. Here's a current-as-of-2026 guide to the battery options actually being installed in LA homes.
Lithium Iron Phosphate (LFP) Dominates
Every major residential battery on the LA market in 2026 uses LFP chemistry - safer, longer-cycle-life (6,000+ cycles), and no cobalt. Tesla Powerwall 3, Enphase IQ Battery 5P, Franklin aPower, FranklinWH, and SolarEdge Home Battery all run LFP. NMC batteries (older Powerwall 2 generation) have largely been phased out of new installs.
Top Systems on the LA Market
- Tesla Powerwall 3: 13.5 kWh, integrated solar inverter, whole-home backup
- Enphase IQ Battery 5P: 5 kWh modular (stack up to 80 kWh), microinverter ecosystem
- Franklin aPower 2: 15 kWh, robust DIY-friendly app, transparent pricing
- FranklinWH FHP: 13.6 kWh, generator integration, smart home control
- SolarEdge Home Battery: 9.7 kWh, pairs natively with SolarEdge inverters
Sizing for Your House
For peak-shifting alone under today's export economics, 10–13 kWh is the sweet spot for most LA homes. For whole-home backup including AC and EV charging during outages, 20–30 kWh is realistic. The right answer depends on your peak-window usage and backup priorities - we model both scenarios before recommending.
AC-Coupled vs. DC-Coupled
AC-coupled batteries (Powerwall, Franklin) can be added to any existing solar system. DC-coupled batteries (Enphase, SolarEdge) are more efficient (96–98% round-trip vs. 89–92%) but typically require matched-brand solar inverters. For new installs, DC-coupled wins on efficiency; for retrofits, AC-coupled is the easier upgrade.
Incentives Stack
30% federal credit applies to standalone battery installs (since 2023) - you don't need to pair with solar. California SGIP rebates still active for qualifying low-income, fire-zone, and medically vulnerable households. Some are now covering 100% of battery cost for eligible customers.
Pick the Right Battery the First Time
Battery selection drives 15-year economics. We don't push a single brand - we model 2–3 options against your usage and let you decide. Call Green Home Remodeling at (800) 650-9055.
