Home battery storage in Altadena, CA
Tesla Powerwall, Enphase, and FranklinWH battery systems for Altadena homes — outage backup, NEM 3.0 economics, and the owner's personal design review.
Home battery storage in Altadena carries more weight than almost anywhere we work. For families rebuilding after the Eaton Fire, the battery belongs in the architectural plans from the first roof drawing — conduit in the walls, the backup-loads panel and main panel sized once, storage integrated with the Title 24 solar the rebuild already requires. Done during construction it is cleaner and cheaper than any retrofit. For the Altadena homes still standing, the case is the foothill classic: the community sits against the San Gabriels in territory where SCE runs Public Safety Power Shutoffs during wind events, and under NEM 3.0 a battery also earns daily by carrying stored midday solar through the expensive 4–9 PM peak. Either way, we design around what your household actually needs through an outage, and we work in this community with care.

How we design your Altadena battery.
- 1
How much do you use?
We pull your last 12 months of SCE data and build an hourly load profile — we size for your real life, not a generic average.
- 2
What matters in an outage?
We design the backup-loads panel around your definition of "good enough" during a shutoff — fridge, internet, well pump, and AC if you need it.
- 3
Single battery or stackable?
We model one unit vs. two and show you the real runtime difference for your home and outage exposure.
- 4
Install & commissioning
We pull every Altadena permit, handle Southern California Edison paperwork, and verify the system before we leave. Most installs finish in 1-2 days.
Our promise: real outage-runtime modeling and every cost itemized before you decide, with a 10-year workmanship guarantee on every Altadena install.
Altadena battery questions, answered.
- Should I add a battery during my Eaton Fire rebuild?
- If backup power matters to you, the rebuild is the cheapest moment you will ever have to add it. The wiring, backup-loads panel, and battery location get designed into the plans instead of retrofitted around finished walls, and the Title 24 solar system the rebuild requires is sized alongside the storage in one pass. We coordinate directly with your architect or builder so it's engineered in, not bolted on.
- How much does a home battery cost in Altadena?
- Most single-battery installs in Altadena land between $10,000 and $16,000 installed, depending on the unit and electrical scope — and folding storage into new construction during a rebuild typically prices at the lower end because the electrical work is already open. Larger foothill homes that want AC coverage through an outage often step up to two units, and we show that comparison honestly.
- Does SGIP help with an Altadena battery after the Eaton Fire?
- It can, but we're careful about promises. SGIP's general-market budget is waitlisted; the meaningful path is the program's resiliency tiers, which prioritize high fire-threat areas and medical baseline households — categories many Altadena addresses fit. We check your specific address and situation against what's actually open before it goes in a quote.
