How Generac Generators Work

Generac generators are permanently installed outside your home and connected to your electrical panel. They run on natural gas or propane and are designed to automatically start within seconds of a power outage. Once utility power is restored, the generator shuts off on its own and your home returns to normal operation.

Unlike portable generators, Generac standby systems are:

• Automatic – No manual setup or fueling required.

• Continuous – Can run for days or weeks, depending on fuel supply.

• Safe – Professionally installed with built-in safety and monitoring features.

How Generators Fit with Solar + Batteries

Solar panels generate power during the day, and batteries store excess energy for nighttime or outages. However, during prolonged grid failures, cloudy weather, or heavy energy use, a battery can be depleted. This is where a generator becomes an essential part of a resilient energy system.

A properly designed system can:

• Prioritize Solar First – Your home uses solar and battery power whenever available.

• Activate Generator When Needed – If battery reserves drop too low or demand exceeds supply, the generator automatically turns on.

• Keep Batteries Charged – Generac can recharge your battery bank, extending your solar backup system indefinitely.

Benefits of Adding a Generator to Solar

• True Energy Independence – Never worry about outages or extended grid failures.

• Flexibility – Choose whether to back up essential loads (lights, refrigerator, internet) or your entire home.

• Long-Term Reliability – Generac generators are built for continuous operation during emergencies.

• Seamless Integration – Designed to work alongside modern solar and storage systems.
