Generac builds air-cooled home standby generators in a range of sizes, from units that cover essentials to ones that can run most of a large home. Many current Guardian models include built-in Wi-Fi so you can check status on the Mobile Link app.
After long JCP&L outages like Tropical Storm Isaias, many Marlboro families added a Generac. That means many units in town are now several years old and due for regular maintenance, battery replacement and occasional repairs.
Picking the Right Generac Guardian for Your Home
Generac makes many sizes. The right one depends on what you want running during an outage.
| Coverage goal | What it usually runs | How we set it up |
|---|---|---|
| Essentials | Fridge, sump pump, furnace fan, lights, Wi-Fi | Smaller Guardian with a transfer switch covering selected circuits |
| Most of the home | Plus kitchen, laundry and one AC unit | Mid-size Guardian with a whole-house transfer switch |
| Whole home | Nearly everything, including multiple AC units | Larger Guardian with Smart Management Modules to balance big loads |
The full process, permits and placement rules are covered on our whole house generator installation page.
