  • Patent number: 11028786
    Abstract: A portable generator includes a CO sensor module to sense CO levels in the environment surrounding the portable generator. The CO sensor module senses high levels of CO and sends a signal to shut down the engine on the portable generator. The CO sensor module alerts the user by emitting an LED light whether the CO sensor module is functioning properly, improperly or if high CO levels are detected. The CO sensor module is removable from a control panel of the portable generator to be replaced or maintained by the user per a replacement or maintenance schedule.

  • Patent number: 10920665
    Abstract: A method and system for exercising a standby generator is disclosed. The standby generator can be exercised in at least two different exercise cycles, including an express exercise cycle and an extended exercise cycle. The system and method operates the generator for an express exercise cycle having a first duration when the ambient temperature at or near the standby generator exceeds a minimum threshold temperature. If the ambient temperature does not exceed the minimum threshold temperature, the express exercise cycle does not begin. In addition to the express exercise cycle, the engine of the standby generator is started and run for an extended exercise cycle having a duration that exceeds the duration of the express exercise cycle. The extended exercise cycles are separated by a first interval while the express exercise cycles are separated by a second interval, where the first interval is longer than the second interval.
