Power management system that includes a generator controller
View Patent ↗Some embodiments relate to a power management system that includes an engine-driven generator and a plurality of load switching and sensor modules that are located remotely from the generator. The load switching and sensor modules include power switching devices and/or sensor circuits. In some embodiments, the power switching devices are operated to selectively provide protected power from a breaker to loads. The power management system further includes a generator controller that is mounted to the engine-driven generator. The generator controller is configured to operate the engine-driven generator and the sensor and load switching modules. The generator controller is further configured to receive input signals from the load switching and sensor modules via a databus, and provide commands to the load switching and sensor modules via the databus to operate the power switching devices and selectively provide power to loads.
