The units eliminate the high expense of other alternative energy options. Their affordability, reliability, and low emissions make them a great option.
Heavy-Duty Residential and Commercial Backup Systems
- Guardian® Series (25, 30, 45, 60 kW Units): As the larger units in the Guardian® Series, the increased power of these generators can provide whole-house backup for larger homes and are ideal for small to medium-size commercial applications, such as convenience stores, restaurants, and offices..
- QuietSource® Series (22, 27, 36, 48 kW Units): Considered the premier series of standby generators, the QuietSource® Series units are equipped with advanced features, such as a quiet, low-speed engine, and are well suited for large residential and small to medium-size commercial applications.
