Sentalis 200 PV Performance Monitoring System:

System Overview

Sentalis 200 monitoring solutions covers all aspects of monitoring the performance of your renewable energy system.  They are packaged as complete solutions including a pre-programmed data acquisition system with appropriate instrumentation to immediately start collecting data on your energy system and pre-configured data communication hardware that connects your site with Draker’s data management services.

Sentalis 200 instrumentation integrates a Campbell Scientific data management and control module with other high quality components to provide accuracy and long term reliability in the field.

All sensor and measurement devices are included with mounting hardware, cables and appropriate enclosures. The data acquisition system includes internal battery back-up and is housed in an outdoor rated enclosure that is designed for quick and easy installation. Sentalis 200 products are designed and manufactured by Draker Laboratories Inc.

 

Graphical User Interface(GUI)

Performance data form the green technologies that are being monitored, will be consolidated in the Sentalis Unit and transmitted to our Draker Data Center for secure archival and processing. The consolidated performance information will be made available via a dedicated Web Site.

A standard GUI is provided to make system performance visible. Thesevisualizations are organized in web pages and include the followingcomponents for exploring recent and historical data trends: 

• Dials - The dials, or gauges, visually give the user a quick glance into the data. They can be used to show a single value within a range, or to compare multiple values.
• Data Tables - These dynamic tables display different values depending on the type of data selected. Tabs below the graph can be used to change the type of data displayed.
• Graphs - Graphs allow the user to explore the data in more detail. They can choose to look at the last two days, 7 days, 31 days, or define a range of their own. Tabs below the graph can be used to change the type of data displayed.
