The Texas Grid
Can't Always Protect You.

Serving San Antonio, Bexar County & Surrounding Areas

Texas operates on its own independent power grid — ERCOT. That independence means when demand spikes in the summer or a winter storm hits, the grid is vulnerable. Rolling blackouts, extended outages, and emergency load shedding have affected hundreds of thousands of San Antonio homes in recent years.

A standby home generator changes everything. Unlike a portable unit you have to manually start and fuel, a standby generator runs automatically within seconds of a power failure — protecting your food, your HVAC system, your medical equipment, and your family's safety around the clock.

During Winter Storm Uri, millions of Texas homes lost power for days. A properly installed standby generator — connected to your natural gas or propane line — would have kept those homes fully operational throughout the event.

Complete Energy Independence

Pair Your Generator
with Solar + Battery
for Total Protection

A generator alone is powerful. A generator paired with solar panels and battery storage is a complete energy independence system.

TXEN Solar specializes in designing and installing all three components as a unified system — so they work together intelligently, not against each other. Your solar charges your battery during the day. Your battery powers your home at night. And when an extended outage hits, your generator takes over automatically to keep everything running.

  • ✔
    Reduce how often your generator needs to run — saving fuel and wear
  • ✔
    Eliminate nearly all grid dependence during normal operation
  • ✔
    Maintain power indefinitely during extended outages

Why TXEN Solar

Engineering-Backed.
Veteran-Owned. Local.

Most generator installers are HVAC or electrical contractors who added generators to their list. TXEN Solar approaches generator systems the same way we approach solar — with engineering precision and a commitment to getting it right the first time.

Up to 10-Year Warranty

As an authorized Briggs & Stratton dealer, we unlock up to a 10-year warranty on every unit we install — the best coverage available, and something an unauthorized installer can't offer you.

Proper Sizing — Not Guesswork

Under-sized generators fail under load. Over-sized units waste fuel and money. We calculate your home's exact power requirements before recommending any unit.

Solar Integration Ready

Planning solar now or later? We design generator installations with solar compatibility in mind so you never have to start over when you're ready to add panels.

We Repair All Brands

Already have a generator that isn't working right? We diagnose and repair any brand, any model — whether we installed it or not.

Common Questions

Generator Questions
Answered Honestly

As an authorized Briggs & Stratton dealer, TXEN Solar offers up to a 10-year warranty on every generator we install — the longest coverage in the industry. This is only possible through an authorized dealer. A big-box store purchase or an install by an unauthorized contractor simply cannot unlock this level of protection. That said, we install all major brands — Generac, Kohler, Cummins, and Champion — and will recommend whichever unit best fits your home, budget, and long-term goals. Every installation comes with our warranty commitment, regardless of brand.
Generator sizing depends on your home's square footage, HVAC system, number of major appliances, and whether you want partial or whole-home coverage. A typical San Antonio home between 2,000–3,500 sq ft is usually well served by a 20–26 kW unit. We calculate your exact load during the free assessment so you never buy more or less than what you need.
No — and this is one of the biggest advantages over portable generators. Standby generators connect directly to your home's natural gas line or a dedicated LP (propane) tank. That means unlimited runtime during an outage with no refueling required. As long as gas service is available, your generator will keep running.
Most whole home standby generators — including Briggs & Stratton, Generac, and Kohler units — start automatically within 10 to 30 seconds of detecting a power outage. The automatic transfer switch (ATS) senses the grid failure and initiates the startup sequence. You don't have to do anything.
Yes. We diagnose and repair generators from all manufacturers regardless of who installed them. If your generator won't start, is producing fault codes, or failed its last load test, contact us for a diagnostic. We work on Briggs & Stratton, Generac, Kohler, Cummins, Champion, and most other residential standby brands.
Yes — and this is one of our specialties. TXEN Solar designs layered energy systems that combine solar panels, battery storage, and standby generators into a single, intelligently managed system. Each energy source serves a different role so your home stays powered under every scenario. We install all three components and integrate them correctly so there are no conflicts or safety issues.
Yes. Installing a standby generator requires electrical and gas permits from the City of San Antonio. TXEN Solar handles all permitting, inspections, and utility coordination as part of every installation. You don't need to manage any of that paperwork.
