Wireless annunciator for an electrical generator
First Claim
1. A power system comprising:
- an electrical generator that converts mechanical energy to electrical current for powering loads of an electrical system during utility power interruption;
a wireless communication system that includes a wireless annunciator and facilitates the wireless transmission of data between the electrical generator and the wireless annunciator;
a first sensor sensing an operational characteristic of the electrical generator and a first wireless module operatively connected to the first sensor, wherein the first wireless module is configured to transmit data relating to the electrical generator to the wireless annunciator;
a second sensor sensing an operational characteristic of the electrical system and a second wireless module operatively connected to the second sensor, wherein the second wireless module is configured to transmit data relating to the electrical system to the wireless annunciator; and
wherein the wireless annunciator receives data transmitted from the first and second wireless modules and is configured to convey information relating to the operational characteristics of the electrical generator and the electrical system to a user by displaying the information relating to the operational characteristics of the electrical generator and the electrical system at the wireless annunciator.

Abstract
A wireless annunciator for an electrical generator displays data regarding operation of the electrical generator to provide feedback to a remote observer regarding performance of the electrical generator in meeting the demands placed thereon. The wireless annunciator wirelessly receives transmissions from one or more wireless modules and displays information based on the data contained in the transmissions. The wireless modules may be associated with sensors, for example, that measure various performance parameters of the electrical generator, such as current draw, fuel level, fuel pressure, and the like. A load management controller can communicate with one or more load-side modules, either wirelessly or across wired links, to control operation of one or more loads to avoid overloading of the electrical generator.
