Standby Generators

Standby Generators for Reliable Backup Power

Standby generators provide automatic backup power when utility service is interrupted. Permanently installed and connected directly to your home’s electrical system, these generators start automatically within seconds of a power outage — restoring electricity to essential circuits or the entire home.

Unlike portable generators, standby systems require no manual setup, refueling, or extension cords. Once installed, the generator monitors utility power and activates automatically whenever an outage occurs.

Whole-Home Backup Power Systems

Standby generators are designed to support critical household systems during power outages, including:

• Heating and air conditioning systems
• Refrigerators and freezers
• Lighting and electrical outlets
• Security and surveillance systems
• Internet and communication equipment

Proper generator sizing ensures the system can safely support your home’s electrical load and operate reliably during extended outages.

Professionally Planned Generator Systems

Selecting the right standby generator requires evaluating electrical load requirements, installation location, and long-term backup power needs. Proper planning helps ensure the generator is sized correctly and installed according to manufacturer specifications and local electrical codes.

Standby Generator Buying Guide

Choosing the right standby generator involves more than simply selecting a unit with enough power. Factors such as electrical load requirements, fuel source availability, installation location, and long-term reliability all play an important role in selecting the right system.

Standby generators are designed to provide automatic backup power during utility outages, restoring electricity to essential circuits or the entire home within seconds.

Understanding a few key considerations can help homeowners choose the most appropriate generator system for their property.

What Size Generator Do I Need for My Home?

Determining the correct generator size depends on the electrical loads you want to power during an outage. Some homeowners choose generators that support only essential circuits, while others install systems capable of powering the entire home.

Generator sizing is based on several factors, including:

• total electrical load requirements

• HVAC system demand

• appliance and equipment usage

• whether the generator will power essential circuits or the entire home

Because every home has different electrical requirements, proper generator sizing begins with a professional load calculation.

A properly sized standby generator ensures reliable backup power while avoiding unnecessary oversizing or performance limitations.

Whole-Home vs Essential Circuit Backup

Standby generators can be configured to power either essential circuits or the entire home.

Essential circuit systems typically power critical loads such as refrigeration, lighting, security systems, and communications equipment.

Whole-home systems provide enough capacity to support larger loads including HVAC systems, appliances, and other high-demand equipment.

Fuel Options for Standby Generators

Most standby generators operate on natural gas or propane, providing a continuous fuel supply during extended outages.

Natural gas generators are commonly connected directly to municipal gas lines, while propane systems rely on on-site fuel tanks.

Selecting the right fuel source depends on property infrastructure and fuel availability.

Professional Generator Planning & Installation

Standby generator systems require proper planning to ensure safe and reliable operation. Installation involves electrical integration, transfer switch configuration, fuel supply connections, and compliance with local building and electrical codes.
