Generator Installation &
Backup Power Systems
Keep the lights, refrigerator, and A/C running when the grid goes down. Elevate Electrical Solutions installs and connects standby and portable generator systems for homes across San Antonio: transfer switches, dedicated circuits, permits, and inspection, all handled by a licensed local electrician.
Why Texas Homeowners Are Adding Backup Power.
Texas runs its own power grid, and it's under the most strain at the same times you need it most: triple-digit summer afternoons when every A/C in the state is running, and hard winter freezes when heating demand spikes. ERCOT conservation alerts, storm damage, and neighborhood outages have pushed a lot of San Antonio families to stop treating backup power as a luxury.
A properly installed generator keeps the essentials running: refrigeration, HVAC, well pumps, medical equipment, a home office, garage doors, and security systems. The difference between a generator that works when you need it and one that doesn't usually comes down to the electrical installation.
We install and connect the generator you choose, or help you size one and recommend trusted options. Serving San Antonio and surrounding communities including Alamo Ranch (78253), Stillwater Ranch & Davis Ranch (78254), Helotes, and Boerne.
- Automatic transfer switch installation for standby generators
- Manual transfer switches & panel interlock kits for portable generators
- Generator inlet boxes & dedicated generator circuits
- Load calculations & generator sizing
- Panel upgrades when your existing panel can't support a transfer switch
- Permits, inspections & code-compliant installation
Standby vs. Portable: Which Is Right for You?
Whole-house standby generators are the hands-off option. They switch over automatically, can be sized to run the whole home including central A/C, and run on your natural gas or propane supply, so there's no refueling during a long outage.
Portable generators with a manual transfer switch or interlock cost less up front. You roll the generator out, plug it into the inlet we install, and choose which circuits to power, typically the refrigerator, some lights, outlets, and a window unit or furnace blower.
Either way, the electrical work follows the same steps:
- Load assessment to decide what you want to keep running
- Panel evaluation, including a panel upgrade if needed
- Transfer switch or interlock installation
- Dedicated circuit and inlet wiring from the generator location
- Permit, inspection, and a final test of the switchover
Generator Installation FAQs
Where can I find generator installation near me in San Antonio?
Elevate Electrical Solutions installs generators throughout San Antonio and the surrounding area, including Alamo Ranch, Helotes, Boerne, Leon Valley, Stone Oak, and the rest of our service area. We're a licensed Texas electrical contractor (TECL #38390), so the transfer switch, wiring, and permits are handled by the same local team from start to finish.
Do you do whole house generator installation in San Antonio?
Yes. For whole house generator installation in San Antonio, we handle the electrical side of the project: sizing the system to your home's loads, installing the automatic transfer switch, running the circuits from the generator to your panel, pulling the permit, and coordinating the inspection. The gas line and concrete pad, when needed, are handled by the appropriate licensed trades.
Why hire a backup generator electrician instead of doing it myself?
Connecting a generator to your home's wiring without a proper transfer switch or interlock can back-feed power onto the utility lines, which is dangerous for lineworkers and can damage your equipment. A licensed backup generator electrician makes sure the connection is isolated from the grid, sized correctly, permitted, and built to code.
What does generator transfer switch installation involve?
Generator transfer switch installation means adding a switch (automatic or manual) between your utility service and your generator so your home can safely change power sources. Automatic transfer switches are used with standby generators and switch over on their own when the power goes out. Manual transfer switches and panel interlocks are used with portable generators and let you power selected circuits through a dedicated inlet.
Do you install generators in 78254 and 78253 (Stillwater Ranch, Davis Ranch, and Alamo Ranch)?
Yes. We're based in 78253, so Alamo Ranch is our home turf, and the 78254 neighborhoods along the Potranco Road corridor, including Stillwater Ranch and Davis Ranch, are minutes away. Most of these homes are newer construction, which usually means a modern panel that's straightforward to connect to a transfer switch or interlock. HOA review for exterior equipment is common in these communities, and we can provide permit, licensing, and equipment documentation for that approval.
Do you sell generators?
Our focus is the electrical installation. We install and connect the generator you choose, and if you haven't picked one yet, we'll help you size it to your home and recommend trusted options so you get the right fit for what you want to keep running.
