Quietsource Series: Premium features are standard for the QuietSource Series, ultimate standby generator. Thanks to the low-speed engine, it’s so quiet you’ll forget you own a generator until you need it. Ideal for large residential and small to medium commercial applications. Low speed, automotive-style liquid-cooled engine runs at only 1800 rpm during a power outage for a substantially quieter generator, greater fuel efficiency, and longer engine and alternator life. Standard aluminum, all-weather enclosure provides the ultimate protection from the elements. Aluminum’s natural corrosion resistance prolongs the life of your generator and is recommended for salt-air, coastal locations.
Protector+ Series: Generac’s Protector Series offers benefits that competitors can’t match: installation flexibility and cost reduction, as well as reduced emissions compared to diesel gensets, and is backed by the industry’s best warranty offered by Generac. Delivers best-in-class power quality with less than 5% total harmonic distortion (THD) for clean, smooth operation of sensitive business electronics and appliances. Standard aluminum, all-weather enclosure provides the ultimate protection from the elements. Aluminum’s natural corrosion resistance prolongs the life of your generator and is recommended for salt-air, coastal locations.
Understanding Wattage
The overall wattage or power that your generator will need to produce depends both on the quantity and type of items or equipment you want to power. In order to accurately calculate your needs, it’s best to understand what starting wattage, running wattage, and surge wattage are, respectively.
First, your running wattage is the total amount of electricity that you need in order to keep the device running. Second, just as it sounds, your starting wattage is the amount of electricity you need to start the device running. On average, the amount of power you need to start a device is usually three times the amount you need to keep it running. Lastly, surge wattage is the most power you can obtain from your generator.
As previously mentioned, Generac has a Generator Sizing Calculator on their website to assist you in determining which size generator you need to power your home. To make things even easier for you, we went ahead and determined the average home square footage in our various service areas and selected the most common equipment that is run during a power outage to determine three size suitable Generator options best suited for your needs. See the results below.
Keep the following terms in mind while reviewing.
1. Whole House – Want to run all of your appliances and electronics at the same time as if you never even lost power? This is the option for you.
2. Partial Managed Power – If you don’t use all your appliances at the same time (most people don’t) then a smaller generator, paired with a Generac power-management Smart Switch, offers the next best thing to whole-house coverage.
3. Full Managed Power – If you don’t use all your appliances at the same time (most people don’t) then a smaller generator, paired with a Generac power-management Smart Switch, offers the next best thing to whole-house coverage.
