Home generators can help you sit out the next blackout in style, but they can also be gluttons when it comes to using fuel—and loud when they’re running. A patented variable-speed technology on Generac’s Guardian Synergy generator promises to address both those concerns. Generac announced the new model at Design and Construction Week in Las Vegas.
Most generators run at a constant 3,600 revolutions per minute to produce current. Generac’s new whole-house model can toggle down to just 2,700 rpm when less power is needed. Slower engine speeds mean less noise and lower fuel consumption plus smoother power, according to Generac. The company also claims you can install it as close as 18 inches from the house if local laws permit.
Generac’s Guardian Synergy generator costs about $5,200. But with 20 kilowatts, it should power everything in most homes, and then some. It also includes the transfer switch that you’ll need for direct hookup. And—yes—you can monitor it right from your smart phone.
