What Is a Home Standby Generator?

A Generac home standby generator is a permanently installed backup power system connected directly to your home’s electrical service and fuel supply (natural gas or propane).

When utility power fails:

1. The automatic transfer switch detects the outage
2. The generator starts automatically
3. Power is restored to your home in seconds

When power returns, the system safely switches back and shuts itself off.

You don’t have to do anything.

Why Homeowners Install Standby Generators

Power outages are becoming more common across Maryland, DC, and Northern Virginia due to storms, grid overload, and infrastructure failures.

A standby generator can provide power to:

• Heating and air conditioning systems
• Refrigerators and freezers
• Sump pumps and well pumps
• Medical equipment
• Home offices and internet
• Security systems
• Entire electrical panels

Many homeowners install generators after their first major outage, however we recommend doing it now so that you don’t have to go through that experience.

Our Generator Installation Process

TriStar Electric installs generators the right way, not the fastest way.

Step 1 – Load Calculation & System Sizing

We evaluate your home’s electrical demand to determine the proper generator size. Oversizing wastes money. Under sizing causes failures.

Step 2 – Site Planning

We determine the best generator location based on:

• Code clearances
• Safety
• Exhaust direction
• Noise considerations
• Fuel routing
• Service accessibility
• Electrical Feed routing
• Aesthetics

Step 3 – Permits & Utility Coordination

We handle electrical permits and inspections required by local jurisdictions.

Step 4 – Professional Installation

Your installation includes:

• Generator and Generator Pad placement
• Automatic transfer switch installation
• Electrical wiring and connections
• Gas Piping and connections
• Startup testing and commissioning

Step 5 – System Testing

We simulate an outage and confirm the system carries load safely.
You will know exactly how your generator works before we leave.

Natural Gas or Propane Generator Options

We install Generac standby generators using:

• Natural Gas – Unlimited runtime during outages
• Propane – Ideal where gas service isn’t available and eliminates the risk of a gas service failure.

We help you choose based on availability, load size, and reliability during regional outages.

Automatic Electrical Backup Systems

When the power fails, everything in your house does too, including the heat, air conditioning, lights, and other essential systems like refrigeration. Depending upon the circumstances, you and your family could be without power for days or weeks. You risk losing food that needs to be refrigerated or frozen, and other systems, like sump pumps and wells, could malfunction and damage your home.

TriStar Electric can install an automatic electrical backup system – also known as a generator – that keeps your house running, even when everyone else on your block is in the dark. These generators range in size and cost, and can be programmed to run only certain services your home requires – like lighting and refrigeration.

We are a certified dealer of Generac generators, the largest generator manufacturer in the United States. Dependable and durable, these generators will be ready when you need them and can be powered by natural gas, propane, and diesel fuel. Easy to maintain, and affordable, these generators are perfect for any size house.

An automatic electrical backup system needs to be installed by a professional who has experience with this type of equipment. In addition, an installer needs to file for the proper gas and electrical permits. This ensures that when it is installed, the automatic electrical backup system will pass inspection.

TriStar Electric has installed thousands of these systems, and we have created a detailed process that enables our electricians to hook up an automatic electrical backup system quickly and efficiently. With our experience and talent, we can design a system that powers parts of the house, or the entire dwelling. Regardless of what you select, our design will suit your budget. When the process is complete, you and your family will never have to worry about winter or summer storms knocking out your power.

In addition to installing these systems, we offer service and maintenance plans to keep them in exceptional shape. You would not want your backup system to fail when you need it. These plans ensure regular maintenance is performed, and that the system is in excellent working order.

Choosing the right system does not have to be difficult, not when you work with a professional service like TriStar Electric. We will meet with you and determine the right size system for your home and your requirements. From our first visit to the final install, you will receive top-quality customer service from everyone at TriStar.
