Guardian Generator

An automatic standby generator is a backup electrical system that operates whether you are at home or away. It automatically supplies power to essential circuits of your home within seconds of a utility outage. After utility power returns, the generator shuts itself off and awaits the next outage. It operates on natural gas or liquid propane gas and sits outside just like a central air conditioning unit.

GENERAC generators supply electricity to the electrical panel circuits of your home through a built-in load center. You select the number of circuits you want to protect and match it to the appropriate generator system. Everything on that circuit will be protected. GENERAC also powers furnaces, air conditioners, well pumps, water heaters and other appliances that are hard-wired into your home’s electrical distribution panel.

While portable generators do supply much-needed backup power to your home during a utility outage, an automatic standby generator produces a higher quality of electricity. It operates automatically and runs a weekly self-test to ensure a proper response to your needs. There are no extension cords to plug in and no gas tanks to fill. It responds to the outage for you, so it protects your home even when you’re away. When utility power returns, the standby generator shuts itself off.

Establishing wattage requirements of the appliances you want to power during an outage is difficult because those appliances can be plugged into various outlets in your home. That’s why GENERAC has simplified the process. By allowing you to protect everything on chosen circuits, you no longer have to worry about individual items.

Air-cooled units use engines we design and manufacture specifically for our smaller generators. Volume production helps us to keep costs down, making our air-cooled generators the most affordable for our customers. They cover essential circuits and backup power needs in most residential applications. Liquid-cooled units use automotive engines for increased horsepower. This makes them ideal for larger requirements such as whole-house power coverage, larger homes, and commercial applications.

Just like your car’s engine, generators need periodic oil and filter changes. Many customers rely on GENERAC’s maintenance kits to satisfy routine maintenance requirements. Refer to your owner’s manual for routine maintenance procedures and schedules. Any authorized GENERAC dealer can perform routine maintenance.

Aluminum is corrosion resistant, so it prolongs the life and looks of the generator, particularly in coastal communities where salt air can quickly penetrate and corrode most metals.

Whisper-Test is a feature that reduces noise by up to 50% during the generator’s weekly self-test cycle. That makes it as quiet as a car idling in your driveway. The generator starts up and operates at a reduced speed, lowering sound output by as much as 12 decibels for units that normally run at higher speeds under load. This allows for near-silent operation in test mode and satisfies all known sound ordinances.

The most accurate way is to have an electrician apply an amp meter to the circuits or appliances that will operate with emergency backup power. Measurements should be taken as the appliance starts up. That’s because a start-up requires the greatest amount of power.

To eliminate the hassle of this process, GENERAC allows you to simply match your system to the existing circuits in your electrical panel. With our 8, 10, 14, or 16-circuit, pre-wired systems, we take the guesswork out of sizing. For customers concerned with air conditioning, the wattage rating of the generator and its circuit breakers inside the transfer switch should be reviewed so that A/C startup power requirements are met.

For liquid-cooled models, a licensed electrician must perform a site survey to determine the size and voltage of the unit to meet your backup power needs.

GENERAC air-cooled models, which come equipped with a comprehensive installation manual, can take as little as four hours to install. They come pre-mounted on a composite pad to further simplify installation. Liquid-cooled generators normally require up to 14 hours to install. Because of their additional weight, liquid-cooled units must be installed on a stronger mounting surface such as a concrete slab.

Note: Time estimates are based on typical applications. Additional time may be required to run an extended electrical conduit or bury gas piping or place the unit far from the incoming gas or electrical service.
