The solar inverter incorporates programmable logic controllers, variable frequency drives, and protective relays. The 250 kW inverter has active front-end technology, which can operate in harsh environments with 24/7 operation cycles. It has a 96.5% efficiency rating from the California Energy Commission.
Annual Salary Survey
After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.
The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
