Home battery storage in Castaic, CA
Tesla Powerwall, Enphase, and FranklinWH battery systems for Castaic homes — outage backup, NEM 3.0 economics, and the owner's personal design review.
Home battery storage in Castaic is a fire-country priority first and a savings tool second. Much of Castaic — Hasley Canyon, Val Verde, the hills around the lake — sits in a High Fire Threat District, and SCE runs Public Safety Power Shutoffs through these neighborhoods when Santa Ana winds blow. A battery keeps your fridge, internet, lights, and well pump running automatically when the grid drops, with no generator to fuel during fire weather. It also earns its keep year-round: under SCE's NEM 3.0, storing your midday solar for the 4-9 PM peak instead of exporting it for pennies is what brings a Castaic payback into single digits. We design the backup around the outages that actually hit your street and the loads you actually need to keep on.

How we design your Castaic 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 Castaic 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 Castaic install.
Castaic battery questions, answered.
- How long will a battery power my Castaic home in a PSPS shutoff?
- On critical loads — fridge, internet, lights, well pump — a single Tesla Powerwall 3 typically runs 2-3 days. Add summer AC and runtime drops to hours per battery, which is why larger hillside homes here often choose two units. We model your real outage scenarios before sizing.
- Does the SGIP battery rebate apply in Castaic?
- Yes, at a meaningful tier for the fire-zone parts of town. California's SGIP program pays substantially larger battery rebates for High Fire Threat District addresses and medically vulnerable households. We verify your exact Castaic address against the active SGIP resiliency tiers before quoting.
- Is a battery better than a generator for Castaic outages?
- For most homes, yes. A battery starts automatically with no fuel and no noise, which matters during the wind events that trigger shutoffs, and it earns money daily through NEM 3.0 arbitrage — a generator only pays off during an outage. For very long rural outages some Castaic homes pair both.
