If a backup generator can't survive years of engine vibration and severe weather, it shouldn't be protecting your home.

Cheap wire connectors and unsealed electronics are the primary causes of generator failure in standard units. The Briggs & Stratton PowerProtect+ line solves this with commercial-grade upgrades designed to prevent electrical faults before they happen.

• Vibration-Proof: Positive-locking terminals snap together securely and will not shake loose.
• Moisture-Proof: Sensitive voltage controls are fully sealed in a waterproof protective compound.
•Reliability-First: Engineered to start flawlessly every single time the power blinks.

Around 3:30 PM every weekday, a few things happen at once: kids come home, laptops and tablets get plugged in, the AC gets turned down, and appliances turn on.

In many areas, that exact window coincides with local utility "peak rates"—the most expensive hours of the day to draw power from the grid.

That’s where the Briggs & Stratton SimpliPHI 6.6 Battery comes in. It stores energy when rates are low (or from solar) and powers your home automatically during expensive peak hours, cutting down your monthly bill without you having to police the thermostat.

Your home backup battery shouldn't just sit around waiting for a storm. It should be lowering your electric bill right now.

Since the federal tax credits ended this year, the smartest way to save money with a battery is by sharing a little bit of your power when the local grid is stressed.

By installing a Briggs & Stratton SimpliPHI 6.6 Battery, you can instantly join local cash-back programs:

• Earn Extra Cash: Get paid credits on your bill for sharing small bursts of electricity during peak hours.
• Stay Protected: You choose your backup limit, so your emergency power never runs dry.
•No Messy Wires: A sleek, compact look that fits neatly on your wall without taking up your whole garage.
