AfterFast, Reliable Solar Battery Storage & Backup Across San Fernando
Solar battery storage in San Fernando typically costs $9,500-$18,500 installed, depending on whether you’re adding one battery to an existing system or pairing multiple units with new solar. Most retrofits on older San Fernando homes take two to four days once permits clear, and our team answers the phone live around the clock. If your power goes out on a 105°F August afternoon, you don’t want to leave a voicemail. Call (877) 550-6892 and Gus or one of his own crew members will pick up.
We know San Fernando’s streets, its permit office quirks, and the electrical panels sitting on its 1940s bungalows. That matters when a battery job hinges on a 100-amp service upgrade that LA City permit runners don’t know how to schedule here.
Why Gus’s Solar Is San Fernando’s Preferred Solar Battery Storage & Backup Company
Gus Petrakis founded Gus’s Solar in 2011, and his name has been on the business since day one. He doesn’t send a sales rep to your door with a tablet full of pressure tactics. He sends a written quote built off your actual SCE bill, tells you to take two weeks, and means it. If a salesman needs an answer tonight, the answer is no. That’s how we’ve operated in San Fernando for years, and the neighbors who’ve hired us keep our number on their fridge.
San Fernando is a 2.4-square-mile city entirely surrounded by Los Angeles. Most solar companies treat it like just another Valley zip code. We don’t. We know this city has its own building department, its own inspection calendars, and SCE instead of LADWP. Those details change how a battery gets permitted, installed, and approved. Get them wrong and your backup power sits unconnected for weeks. Get them right and you’re running off stored solar the night after final inspection.
Every job is handled by Gus’s own background-checked, uniformed crew. Not a sub, not a rotating cast of third-party installers. The same faces at the permit counter are the ones on your roof. And when the job’s done, the 90-Day Done Right Promise applies in writing. If something’s not right, one call brings Gus back. No ticket numbers, no claims department.
Our Solar Battery Storage & Backup Services in San Fernando
Tesla Powerwall Installation
The Tesla Powerwall 3 is the most common battery we install in San Fernando, and for good reason. It handles the valley’s brutal afternoon heat better than earlier models, with an integrated inverter that simplifies retrofits on homes with smaller service panels. A single Powerwall 3 in San Fernando typically runs $12,000-$15,500 before incentives, including the Gateway and full permitting through the city’s building department. Most homes need one; central AC plus a pool pump on a 2,000-square-foot bungalow usually wants two.
Enphase IQ Battery Installation
Enphase IQ batteries make sense when your existing system already runs Enphase microinverters. The integration is cleaner, the monitoring app gives you per-circuit detail, and the modular design means you can start with one 5 kWh unit and add more later. Expect $8,500-$12,000 for a single IQ Battery 5P in San Fernando, including the required Enphase system controller and SCE interconnection paperwork. On tight lots where wall space is scarce, the floor-mount profile often fits better than a larger wall-hung unit.
Whole-Home Backup Power
Whole-home backup in San Fernando means your AC keeps running during a summer outage. That’s the real test. A single battery usually covers essential circuits only: refrigerator, lights, internet, medical equipment, and maybe one small window unit. Two batteries give you a fighting chance at central air for a few hours. We design the backup loads panel around your actual usage patterns, then walk you through exactly what will and won’t stay on when the grid drops. No vague promises.
Battery Retrofit for Existing Solar
Plenty of San Fernando homeowners installed solar between 2015 and 2020 under NEM 2.0, when batteries felt optional. Now they’re not. We retrofit batteries onto existing systems routinely, and we’ll tell you honestly whether your current inverter can accept a battery or needs replacement. On a 1950s bungalow near San Fernando Road and Orange Grove, our crew retrofitted a Tesla Powerwall 3 onto an existing 4.8 kW system whose original string inverter lacked a battery-ready input. The main service panel was only 100 amps, so we coordinated a 200-amp panel upgrade with the city’s building department before the battery could pass final inspection. Since Southern California Edison serves this pocket, we filed the storage interconnection application directly with SCE rather than LADWP. The whole job took three extra days because the plan check had to go through San Fernando’s smaller office.

Trusted Brands We Service in San Fernando
We work with Tesla, Enphase, SolarEdge, and FranklinWH equipment across San Fernando, and we stock common parts locally so a service call doesn’t stall waiting on a shipment. We don’t push a single brand. We recommend what fits your panel, your roof, and your budget. If you already have Tesla equipment, we service it. Same for Enphase and SolarEdge. A battery is a decade-plus purchase, so we’d rather explain the tradeoffs than sell you a badge.
Common Solar Battery Storage & Backup Problems We See in San Fernando Homes
- 100-amp service panels that can’t accept a battery breaker. Most San Fernando homes built in the 1940s through 1960s still carry their original 100-amp main panel. A battery needs a 40-amp breaker, and the permit gets flagged for a 200-amp panel upgrade before anything else moves. Contractors used to LA City’s process often miss this and leave you waiting through multiple inspection cycles.
- SCE interconnection paperwork filed incorrectly. Southern California Edison’s storage tariff treats battery export differently than LADWP’s rules. A system configured for LADWP can fail SCE’s witness test and sit unapproved for weeks. We file SCE paperwork every week, so we know exactly what the utility wants to see.
- Attic rafters that can’t hold a wall-mounted battery. 1940s bungalow rafters often lack the shear rating needed for a heavy wall-mount unit, so the inspector requires structural calculations that delay close-out. We check this before installation day, not after.
- Heat-soaked batteries losing afternoon output. When San Fernando hits 105°F and hot air pools against the San Gabriel Mountains, battery electronics run hotter and charge rates throttle back. Placement matters. We install batteries on shaded walls or in garages wherever possible, and we account for heat derating in the system design so your backup power actually works when you need it most.

FAQs - Solar Battery Storage & Backup in San Fernando
San Fernando operates its own building department, completely separate from LA City’s DBS. A battery permit requires plan check and inspection through that small municipal office, which still relies heavily on phone calls for scheduling rather than an online portal. If a contractor assumes LA City rules apply, your permit stalls. We call the office directly and build the extra lead time into your schedule.
Yes, and significantly. San Fernando is served by SCE, not LADWP, and SCE’s NEM 3.0 tariff pays very little for excess solar sent back to the grid during midday. A properly configured battery lets you store that cheap midday production and use it during expensive evening hours, so the battery effectively replaces what you would have earned under the old net metering rules. We run the exact math off your bill. Call (877) 550-6892 and we’ll walk you through it.
In most cases, yes. We retrofit batteries onto existing systems throughout San Fernando regularly. If your original inverter is battery-ready, the add is straightforward and typically costs $8,500-$15,500. If it isn’t, you may need an inverter replacement or a battery like the Powerwall 3 with a built-in inverter. Either way, we’ll tell you the honest number before any work begins.
That depends on the size of your system and the size of your AC. A single battery will run lights, refrigeration, internet, and medical devices for many hours, but central air is a heavy load. Two batteries will typically run a modern central AC for several hours, especially if you manage other loads. We’ll design your backup panel with realistic expectations, not brochure claims. Call (877) 550-6892 for a free consultation.
Heat is the biggest performance variable. San Fernando sits at the northeast end of the inland valley where summer temperatures regularly exceed 105°F, and batteries in direct sun or hot attic spaces run hotter, charge slower, and lose output. We install batteries on shaded walls, garages, or other protected locations whenever the home allows, and we factor heat derating into every system design. That’s the difference between a battery that works when the grid fails and one that fades exactly when you need it.
