Power source load control

This invention describes a system to prevent power overloads from an AC power source, especially one that can work with or back up the main power grid. It monitors the power source for issues like overheating or overload and then tells connected devices to adjust their power use. It does this by subtly changing the frequency of the AC power, which smart devices then detect and respond to by consuming more or less electricity. The claims specifically focus on an inverter-type power source.

Why it matters: The rapid growth of grid-interactive home energy systems (solar, batteries, EVs) and smart appliances since 2021 has created a greater need for robust, power-line-native communication for demand response and grid stability. This makes frequency modulation a more relevant and feasible signaling method for managing distributed loads.
