Data Loggers

"Now more than ever, Renewable NRG Systems offers an easy-to-use data logger. The plug-and-play SymphoniePRO system shows great improvement over preceding models with expanded channel options and compatibility with virtually all meteorological sensors. Additionally, the ability to live-connect to the logger allows easy access to check status and control data collection."

Daniel Votteler Senior Wind Resource Engineer, SOWITEC development GmbH

Data loggers are the core component of NRG’s complete system approach to wind and solar measurement applications. Data are collected from readings of meteorological sensors and other devices and then stored in our loggers for either manual retrieval or automated delivery to the location of your choice.

Our data loggers are easily configured from the comfort of your office or directly in the field, simple-to-install, and rugged enough to perform reliably worldwide—in extreme cold or tropical environments.

The newest data logger in the Symphonie series, SymphoniePRO® Data Logger, brings with it significant feature upgrades to an unparalleled legacy of purpose-built renewable energy data loggers. Below is a summary table highlighting the major differences to help you understand which of our data loggers is right for you. See the individual product pages to learn more.
