Load Shedding Generator

A Load Shedding Generator System allows a smaller, more efficient, and less expensive standby generator to power multiple high-voltage loads like Air Conditioners or Electric Water Heaters.

Load Shedding Generator System | Power Management

A Load Shedding Generator System allows a smaller, more efficient, and less expensive standby generator to power multiple high voltage loads like Air Conditioners or Electric Water Heaters.

Load shedding allows 240-volt loads to share available power from a standby generator. Different manufacturers employ various strategies in conjunction with an intelligent controller to manage power. Strategies usually prioritize loads. The load with the highest priority always runs first. Lower priority loads run after the higher priority load ends or when the generator has enough capacity to run both.

Load Shedding Generator Management allows smaller, fuel-efficient home generators to provide power without the expense of larger and more costly systems. By sharing the available power, important appliances run when needed and unnecessary loads wait until they finish.

Load Shedding Generator Transfer Switch

Most power management systems implement load shedding through the automatic transfer switch. The transfer switch has a contactor module for HVAC systems, or it might external relay modules to control individual loads.

Frequently Asked Questions

A. Load shedding power management allows a smaller generator to intelligently manage power during an outage to prevent overloading the generator. For example, it can turn off an electric water heater to ensure the air conditioner has the power it needs to run.
A. Different manufacturers have their own strategies. One way detects the output frequency of the generator. If it drops below a certain frequency, the generator is approaching overload, and power management sheds the lowest priority load. Some systems detect current output for individual loads. If adding a load would exceed the maximum level, the load won't run.
A. Air conditioners are heavy users of electricity, but they are also the easiest loads to shed because the control circuits operate on low voltage. Many transfer switches include an air conditioner load shedding module that eliminates the need for extra modules. Other heavy loads, like electric water heaters, use an external relay controlled by the transfer switch or generator controller.
A. A whole home transfer switch will probably have the power management features you need built into it. The National Electrical Code requires enough power for everything in your home based on a load calculation. Without power management, you would need a much larger generator than necessary, which uses more fuel and requires additional maintenance.
