A diagnostic test is conducted by operating an engine-generator set at a plurality of reduced speeds. At each of those speeds, operating parameters of the engine are sensed and analyzed to detect an unsatisfactory operating condition. For example, such operating parameters may include speed of the engine-generator set, engine oil pressure and level, engine temperature, coolant level, and battery voltage. When a transition in engine speed occurs, a throttle test also may be conducted to measure how quickly and smoothly the engine reaches the new speed. After the engine reaches the normal operating speed, the generator is activated to produce electricity. One or more characteristic of that electricity, such as voltage, current and frequency, are sensed and evaluated to detect an unsatisfactory operating condition.

Diagnostic method for an engine-generator set

Systems and methods include operating a power system in a first state, and detecting an anticipated load increase. The systems and methods further include changing operation of the power system from the first state to a second state upon detection of the anticipated load increase.

Power generation system with anticipatory operation

A power management system may include a generator controller. The generator controller may (i) operate the generator; and (ii) prohibit a transfer switch from supplying first or second power to an output of the transfer switch. In some systems, the first power may be primary power (e.g., from a primary power source such as a utility) while the second power is secondary power (e.g., from a secondary power source such as a generator). In other systems, the second power may be primary power while the first power is secondary power, or both the first and second power may be secondary power.

Generator controller configured for preventing automatic transfer switch from supplying power to the selected load

Some embodiments relate to a remote annunciatorthat includes an enclosureand a controlwithin the enclosure. The controlreceives signals S from a plurality of transfer switchesA,B,C,D and at least one generatorthat is connected to at least one of the transfer switchesA,B,C,D. The controldisplays a status of electrical connections that include the plurality of transfer switchesA,B,C,D and the at least one generator. In some embodiments, the controlrecognizes when the plurality of transfer switchesA,B,C,D and the at least one generatorare connected to the control

Remote annunciator

Some embodiments relate to a power management system includes a primary power source and a secondary power source. The power management system further includes an enclosure and an electrical component located within the enclosure. The electrical component is connected to the primary power source and the secondary power source. The power management system further includes a membrane that is mounted to an outside of the enclosure. The membrane extends through the enclosure such that the membrane provides information relating to operation of the power management system.

Power management system that includes a membrane

An automatic transfer switch (ATS) system and method of operating an ATS system for governing the providing of power from first, second and third power sources to a load are disclosed. In one embodiment, the system includes a first ATS device having first and second input ports and a first output port, a second ATS device having third and fourth input ports and a second output port, and at least one communication link coupling the first and second ATS devices. The second output port of the second ATS device is coupled to the second input port of the first ATS device. Additionally, a first signal is provided from the first ATS device to the second ATS device by way of the communication link when power should be supplied from the second ATS device to the first ATS device.
