Fast, Reliable Solar Battery Storage & Backup Across Commerce

If you own or manage a warehouse, distribution center, or manufacturing facility in Commerce, you already know the stakes when the power flickers. A battery backup system sized for your building keeps refrigeration running, dock doors operational, and security systems live when SCE’s grid fails. We install, retrofit, and service commercial battery storage across Commerce’s industrial corridors, and our response time to the Bandini Boulevard and Sheila Street areas is typically same-day when you call before noon. Reach Gus’s Solar at (877) 550-6892 for a straight answer about your building.

Why Gus’s Solar Is Commerce’s Preferred Solar Battery Storage & Backup Company

Gus Petrakis has been running a solar and battery business since 2011, and he’s the one who answers when you call about a Tesla Powerwall retrofit on a Commerce warehouse. We’re not a call center in another state. We’re a local operation that sends our own background-checked, uniformed crew to Commerce job sites, and the team that shows up is the same team that finished your permitting paperwork.

Commerce customers call us because they’ve been burned. A national outfit quotes a number over the phone, sends a subcontracted crew that’s never seen a flat TPO roof before, and disappears when the interconnection stalls at SCE. We don’t do that. Gus’s name is on the building. His license number is published. If the battery system doesn’t perform the way we said it would, the 90-Day Done Right Promise means one call brings Gus back, in writing, on every job.

Here’s what else matters: a live person answers our phone 24/7. No voicemail tree. No ticketing queue. When your battery inverter throws a fault at 6 a.m. and your walk-in freezer is warming up, you talk to a human who knows Commerce’s buildings.

Our Solar Battery Storage & Backup Services in Commerce

Commerce is not a typical residential solar market. It’s a city of roughly 12,000 residents surrounded by tilt-up concrete warehouses, freight yards, and manufacturing plants. That means the battery work here looks nothing like the residential jobs in Maywood or Bell Gardens. We design for 480V three-phase commercial service, flat membrane roof setbacks, and SCE’s commercial time-of-use tariffs. Our Solar Battery Storage & Backup team covers the full scope below.

Tesla Powerwall Installation

Yes, Powerwalls work in Commerce, but the installation is different from a suburban garage wall. Most of our Commerce installs place Powerwall 3 units on ground-level concrete pads adjacent to the building’s main switchgear, not on the roof. That keeps service access simple and avoids point-loading a TPO membrane that was never designed to carry a 300-pound cabinet. We configure the units for peak shaving and demand-charge reduction under SCE’s commercial rate schedules.

Enphase IQ Battery Installation

For smaller commercial suites or owner-occupied buildings with existing Enphase microinverter arrays, the IQ Battery line makes sense. The modular cabinets are narrow enough to fit inside a ventilated electrical room without eating floor space. In Commerce, we specify the 5P configuration with forced-air cooling because unventilated mechanical rooms inside tilt-up warehouses routinely push past 110°F on summer afternoons.

Whole-Home Backup Power

For the limited residential stock in Commerce, most of it mid-century rental housing near the Commerce Casino and the Citadel Outlets, a whole-home backup setup starts with understanding the panel’s existing loads. These older homes often have 100-amp services, so we size the battery and any needed panel derate around what the house actually draws, not a brochure estimate. If a landlord wants to add backup to a fourplex, we work from the actual SCE billing data.

Battery Retrofit for Existing Solar

This is the bulk of our Commerce work. A building already has 100kW, 200kW, or more of rooftop solar permitted years ago under NEM 1.0 or 2.0. Now the owner wants storage. We evaluate the existing inverter, confirm the interconnection agreement, and design a DC-coupled or AC-coupled retrofit without triggering a utility service re-study unless one is unavoidable. We recently completed this on a warehouse off Sheila Street near the BNSF rail yard, retrofitting a Tesla Powerwall 3 alongside a 200kW rooftop array. The aging tilt-up walls had not been seismically retrofitted, so our structural engineer had to verify ballast loads before we could pull permits for the battery pad. With the Powerwall configured for commercial time-of-use peak shaving, the owner now avoids demand charges during the 4 to 9 p.m. window that Southern California Edison enforces in this territory.

Trusted Brands We Service in Commerce

We service and install equipment from Tesla, Enphase, FranklinWH, and Panasonic. That means when a Commerce customer calls with a FranklinWH aGate fault or a Panasonic EverVolt issue, we don’t have to wait a week for a factory specialist. Our crew carries common replacement parts on the truck, and our Los Angeles office can pull inventory for Commerce jobs the same morning.

Common Solar Battery Storage & Backup Problems We See in Commerce Homes

  • Inverter overheating in unventilated mechanical rooms. Tilt-up warehouse electrical rooms with no forced airflow routinely exceed 110°F in summer, and battery inverters derate or shut down entirely. We specify cooling retrofits or relocate equipment to shaded pads before installation, not as an afterthought.
  • Interconnection delays from saturated utility transformers. Many Commerce warehouses sit on commercial transformers already near capacity. Adding battery export can trigger an SCE service upgrade that adds months and thousands to the project. We check transformer headroom before you sign anything, so the timeline on paper is the timeline that happens.
  • Filter and cooling fan failures from freight-corridor particulate. The I-5 and I-710 corridors push diesel soot and brake dust onto Commerce rooftops. That same particulate settles on battery enclosure air filters, clogging intake screens and causing cooling fans to fail early. Quarterly filter replacement is standard on every Commerce battery maintenance contract we write.
  • Structural flagging on pre-seismic-retrofit buildings. Many of Commerce’s older tilt-up warehouses predate modern seismic standards. Adding a battery pad means proving the building can carry new dead loads. If the structural review stalls, the permit stalls. We budget for a structural engineering report upfront on every Commerce project involving roof or mezzanine-mounted equipment.

Pricing for Solar Battery Storage & Backup in Commerce, CA

A commercial battery retrofit on a Commerce warehouse typically runs $48,000 to $140,000 for equipment and installation, depending on capacity and whether a utility service upgrade is required. A single Tesla Powerwall 3 installed for peak shaving on a small commercial suite usually lands between $18,000 and $26,000. Adding multi-unit Enphase IQ Battery 5P stacks for a large distribution center starts around $35,000 and climbs with each additional 10kWh module. Structural engineering reports for older tilt-up buildings add $3,000 to $9,000. These are real numbers from Commerce job sites, not brochure estimates. Call (877) 550-6892 and bring us a year of SCE bills. We’ll build the math off your actual usage and current export rates, and the price we quote is the price you pay.

What San Jose Customers Say

Trusted by homeowners across San Jose and surrounding areas.

★★★★★

"My previous solar company went out of business and left me with an array nobody would touch. Gus took the system over, replaced two dead microinverters, and it has run properly since."

Ferdinand Kaltenbrunner · Verified customer
★★★★★

"Four different companies knocked on my door in one summer and every one of them wanted a signature that evening. Gus has a shop with his name on it, gave me the numbers on paper, and told me to take a fortnight and think about it."

Winifred Castellano · Verified customer
★★★★★

"Honest quoting and good workmanship. He is not the cheapest quote I got, by some way, and he told me that himself and explained what the difference bought. I chose him anyway and I am glad."
