Whole House Power Management

Whole-house coverage may not fit every budget. With a power management system, your generator can work smarter. It protects all your home’s circuits by cycling power on and off as needed for different appliances. And you decide what gets priority.

Smart Management Module

Meet the brains that make smart power possible

These modules are essential to a Generac power management system. They work with your transfer switch, monitoring each selected circuit and automatically supplying power where it’s needed so you can get the most from your generator.

A Generac power management system can use up to eight individual Smart Management Modules, depending on your needs. Just as important, you can set the load priority for each – putting you in control of which circuits matter most.

Generac’s LTE

A critical part of maintaining your generator is making sure there is enough fuel to get you through the unexpected power outages when utility power is lost. Generac now offers a LTE LP Fuel Level Monitor* to measure the amount of LP fuel remaining in your tank. The tank monitor integrates with Mobile Link and Fleet so users can see remaining fuel level in real time, and set low tank level alerts.
*This system is compatible with air-cooled and liquid-cooled models that utilize LP as a fuel source.

Automatic Transfer Switches

Although the generator creates the power, the transfer switch is really the core of your generator system. It is an electrical panel that allows you to safely connect a generator to your home's electrical circuits and is permanently installed near your main circuit breaker panel.
