Hardware

The hardware in this package consists of the core DAQ-EZTM system unit, sensors, mounting hardware and cables.

• The system unit is a waterproof (NEMA 4X) enclosure containing a Campbell Scientific data logging engine, supporting electronics, and a battery.
• The integrated battery backup provides continuous data logging during interruptions to the system unit's normal power source.
• The bottom of the system unit has weather-tight plug receptacles for matching sensor and power cables. The installer is not required to perform any hard wiring.
• The sensors include silicon Pyranometers for plane-of-array and horizontal solar irradiance, a thermistor for back-of-module temperature and an electronic revenue grade AC power and energy meter.
• The package includes mounting hardware and an integrated cable for the Pyranometers and thermistor.

Graphical User Interface(GUI)

A standard GUI is provided to make system performance visible. These visualizations are organized in web pages and include the following components 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.

Optional Packages 

• DC monitoring (system, subarray, string)
• The advanced DC Monitoring option provides a more detailed picture of system performance, breaking out the solar to DC efficiency and the DC to AC efficiency.

• Net Energy
• for measuring building Loads and quantifying the amount of energy that is imported from and exported to the utility grid.
  

• Inverter Communications


• Battery Monitoring


• Weather Station
• Basic and Advanced

• Touch-Screen Kiosk
• Interactive Flash animated displays that facilitate the communication of your commitment to renewable energy.
