Eaton Advances Power Management for Solar Installations Optimizing Energy Harvest and Reliability

Eaton Corporation has introduced PVGard® engineered monitoring system, which helps solar customers monitor and proactively manage solar plant's equipment. The web-based PVGard monitoring system, which Eaton previewed at the Solar Power International Conference in Orlando, alerts customers to underperforming panels, inverters and transformers. Providing advanced predictions of many potential failures, the PVGard system helps customers avoid downtime and maximize energy harvest. The PVGard system was developed to advance solar projects and satisfy power purchase agreements.

"Eaton has an expansive network of application and field service engineers to provide local support for solar customers," said Bill Miller, global marketing director at Eaton. "With the PVGard system and Eaton's engineering support, customers can improve system uptime and reduce maintenance costs by tracking equipment health and identifying power problems before they occur."

With custom algorithms to track multiple inputs, the PVGard engineered monitoring system helps customers maintain and improve system performance. It collects data directly from equipment including PV arrays, inverters, AC equipment and weather parameters. Transmitting data in real-time, PVGard enables customers and plant operators to respond faster to abnormal conditions.

Energy Efficiency with Class D Amplifier Modules

Class-D switching amplifiers are helping audio designers create personal multimedia devices and home audio/visual systems that demonstrate how compact and stylish equipment can also deliver high sound quality and high audio output power. The key to this breakthrough, providing freedom from the large and bulky boxes housing traditional audio products, lies in the class-D amplifier’s high energy efficiency, which is typically around 90%. This allows designers to reduce or eliminate heatsinks as well as using smaller-sized PCBs and smaller components such as transformers, connectors and power supplies.

The Role of Hall Effect Sensors in Power Distribution Infrastructure

Power distribution units (PDUs) form an essential part of modern computing and data communications hardware. They provide multiple outputs for transferring electrical power with maximum efficiency, controlling the power capacity and safeguarding against the possible causes of supply interruption. With an ever increasing need from tech savvy consumers for higher data throughput and greater quantities of data storage capacity, as well as tough international legislation now governing CO&sub2; emissions, the demands being placed on these units are proving challenging for engineering teams to satisfy.
