Product Description
The PVmet weather station provides strategic environmental data that significantly increases
the value of any on-site monitoring system. This fully assembled station allows for rapid out-ofthe
box installation and simple hook up with standard Modbus RTU interface.
Comprehensive Solar Performance MonitoringThe PVMet 75 provides accurate measurement of solar irradiance, ambient and module temperatures, wind speed and direction, and relative humidity. Its sensors ensure reliability and consistency for solar plant optimization, making it a preferred choice among solar professionals and facility managers.
Flexible Installation and IntegrationWith its universal mounting hardware and extendable 10-meter cable, the PVMet 75 is designed to accommodate diverse site requirements. Its NEMA 4X weatherproof enclosure allows for durable, safe outdoor installation, while Modbus RTU compatibility ensures straightforward integration with plant SCADA and monitoring systems.
NIST Traceable, Factory-Calibrated SensorsEach PVMet 75 comes with sensors that are factory calibrated and NIST traceable, providing confidence in data integrity. Periodic recalibration is not necessary for most applications, allowing for reduced maintenance and increased system uptime.
FAQ's of PVMet 75 Solar Monitoring Station:
Q: How is the PVMet 75 Solar Monitoring Station typically installed?
A: The PVMet 75 comes with universal mounting hardware, making it suitable for installation on various structures, including solar racking and poles. Its standard 10-meter cable (which can be extended) offers flexibility in placing the monitoring station in optimal locations on site.
Q: What communication interface does the PVMet 75 support for data output?
A: This monitoring station uses the RS-485 interface with Modbus RTU protocol, enabling seamless integration with most solar data acquisition systems, monitoring platforms, and SCADA solutions commonly used in the industry.
Q: When should I consider using the optional data logging feature?
A: Opt for external data logging if you require local backup of measurement data, want to conduct advanced analytics, or need to meet compliance reporting requirements. This option is useful where continuous data capture beyond standard SCADA integration is desired.
Q: Where can the PVMet 75 be operated and what environments is it suited for?
A: Designed to withstand harsh outdoor conditions, the PVMet 75 operates effectively in temperatures from -40C to +65C and features a NEMA 4X weatherproof enclosure. Its robust design makes it ideal for installations across diverse climates in the United States.
Q: What types of pyranometer sensors are available with the PVMet 75?
A: The station offers a selectable reference cell pyranometer, available in both monocrystalline and polycrystalline options. This allows users to choose the sensor type that best matches their solar modules for optimal irradiance measurement congruence.
Q: How is sensor calibration handled, and what is the benefit?
A: Sensors are factory calibrated with NIST traceable results, ensuring high accuracy and data credibility straight out of the box. This minimizes the need for frequent recalibration and boosts confidence in long-term measurement reliability.
Q: What is the main process for integrating PVMet 75 data into my monitoring system?
A: Once installed and connected via RS-485, simply configure your plant monitoring or SCADA software to communicate using the Modbus RTU protocol. This enables direct access to all measured meteorological parameters for real-time analysis and historical tracking.
