Guardian® home standby generators automatically supply electricity to pre-selected circuits during a utility power outage. Our pre-packaged, pre-wired systems make installation fast, easy and so affordable, you'll wonder why you didn't buy one sooner! And with Guardian, the kilowatt ratings we list are the kilowatt ratings you get. Unlike   our competitors who only cover a percentage of the standby loads, Guardian covers the entire load, for the full duration of the power outage.
