Whole Home Backup Power

Whole-home backup power means exactly that: every circuit, every outlet, every appliance in your home stays on when the grid goes down. No extension cords, no manual switches, no choosing which rooms get power and which don't. When a Carolina ice storm snaps a limb across a power line, or summer thunderstorms trip a substation, your automatic transfer switch detects the outage in seconds and your standby generator takes over the entire load.

The heart of a whole-home system is the automatic transfer switch (ATS). This device monitors utility power continuously. When it detects a loss of voltage - typically below 80% of nominal - it signals the generator to start, waits for the engine to reach operating speed, then transfers your home's electrical load from the utility to the generator. The entire process takes 10 to 30 seconds. When utility power is restored and stable, the ATS transfers back and shuts the generator down.

Sizing is critical for whole-home backup. We perform a load calculation that accounts for your HVAC startup surge, well pump, electric water heater, kitchen appliances, and any medical equipment. In the Carolinas, air conditioning is often the largest single load - a central AC unit can require 5,000 to 7,000 starting watts on its own. We size your generator to handle everything simultaneously, with smart load management if needed to prioritize essential circuits during peak demand.

Whole-home systems connect directly to your fuel supply - natural gas or a large propane tank - so there's no refueling during an extended outage. When hurricane remnants knock out power for three to five days, your generator runs continuously without you touching it. You sleep through the storm with the lights on.

For homes with well pumps, septic pumps, or electric heat, whole-home backup is especially important. These systems aren't just conveniences - they're essential to keeping your home livable during a multi-day outage. A properly sized whole-home generator keeps your water running, your heat operating, and your refrigerator cold for the duration of any Carolina weather event.
