Home Standby Generator Installation in San Antonio
Texas weather can be unpredictable. Severe thunderstorms, high winds, and increasing demand on the electrical grid can leave neighborhoods without power for hours or even days. That’s why many San Antonio homeowners are investing in whole-home standby generators.
Zellner Electric is a Certified Generac Dealer, Installer, and Service Provider, offering complete generator solutions from start to finish. We help homeowners choose the right generator size, handle permitting, install the automatic transfer switch, and perform ongoing maintenance to keep your backup power system operating reliably for years to come.
Unlike portable generators, a whole-home standby generator starts automatically within seconds of an outage, allowing your lights, air conditioning, refrigerator, security system, internet, and other essential appliances to continue operating without interruption.
Electrical Panel Upgrades
Many homes throughout San Antonio were built before today’s electrical demands existed. Modern kitchens, home offices, electric vehicles, smart home technology, and standby generators often require additional electrical capacity that older panels simply weren’t designed to handle.
If your breakers frequently trip, lights dim when appliances start, or you’re planning major home improvements, it may be time to upgrade your electrical panel. Our electricians perform complete panel replacements designed to improve safety while preparing your home for future electrical needs.
EV Charger Installation
Electric vehicles continue to become more popular throughout San Antonio. Installing a Level 2 EV charger at home provides significantly faster charging while adding convenience and value to your property.
Our licensed electricians evaluate your home’s electrical capacity, install dedicated circuits when needed, and professionally install your charging equipment according to manufacturer specifications and local electrical codes.
Lighting That Improves Your Home
Whether you’re remodeling your kitchen, updating your living room, or improving your outdoor living space, professionally installed lighting can completely transform your home.
We install:
- Recessed lighting
- Pendant lighting
- Under cabinet lighting
- Landscape lighting

Every lighting installation is carefully planned to maximize both beauty and functionality while improving your home’s energy efficiency.
