Introduction
Power interruptions are becoming increasingly common due to aging infrastructure, severe weather conditions, and overloaded power grids. For homeowners who value comfort, security, and uninterrupted access to critical appliances and systems, investing in a built-in home generator is no longer optional—it’s essential.
Unlike portable generators, built-in (or standby) generators are permanently installed and can automatically power your entire home within seconds of a blackout. They operate seamlessly, without the need for manual refueling or setup, and are designed to run on more stable fuel sources like natural gas or propane, ensuring long runtimes and minimal maintenance.
