Last week a homeowner proudly showed us their backup plan.

Two portable generators. Six extension cords running through the window. A piece of cardboard “sealing” the gap.

They said, “We only run the fridge and the sump pump.”

We asked, “What happens when the storm hits at 2 a.m.?”

Another pause.

Prepared isn’t just having power. It’s having power without the midnight setup routine.

That’s why more homeowners are choosing automatic standby systems from Briggs & Stratton—power that starts whether you’re awake, asleep, or out of town.

One homeowner told us after their first outage: “The lights came back on before I even realized the power went out.”

That’s the difference between backup power and backup peace of mind.

With utility rates rising across the country, We're helping more homeowners switch to a "peak-shaving" strategy using the Briggs & Stratton SimpliPHI 6.6 battery.

It’s a silent, sophisticated system that stores energy when it’s less expensive and powers your home when rates spike.

Built with LFP technology, it’s one of the safest and most durable options we've ever installed. It doesn't just back up your home; it manages it.
