Details

Cutting-Edge Sensor Technology

At the heart of the Sunmeter Pro lies a high-performance monocrystalline silicon cell. This cell is meticulously laminated with specialized glass used in photovoltaic modules and encapsulated with E.V.A. (Ethylene Vinyl Acetate), effectively creating a micro PV module. This unique construction ensures optimal light absorption and conversion, mirroring the behavior of full-scale solar panels with remarkable precision.

Unmatched Stability and Longevience

The Sunmeter Pro undergoes rigorous stabilization processes and extensive testing to minimize measurement drift over time. This commitment to long-term accuracy sets it apart from conventional irradiance sensors , ensuring that your data remains reliable year after year. With a performance decline of less than 1.5% per year, you can trust the Sunmeter Pro to deliver consistent results throughout its operational life.

Advanced Measurement Capabilities

Incorporating proprietary TZOS® technology, the Sunmeter Pro offers a level of measurement sophistication previously unseen in the industry. This innovative approach to irradiance sensing allows for more nuanced and accurate data collection, providing insights that can significantly enhance the efficiency and output of solar installations.

The Sunmeter 2 LED presents a helpful support feature for quick installation and immediate diagnostics.

Superior Calibration, adjustment and Quality Assurance

Each Sunmeter Pro undergoes a meticulous calibration process, utilizing a stabilized PV reference cell at the DAKKS accredited ISFH (Institute for Solar Energy Research Hamelin). This rigorous calibration ensures that every unit meets the highest standards of accuracy and reliability.

  • LED Interfaces: : LED diagnostics help users easily identify issues such as miswiring or impedance problems in power and data lines
  • User-Friendly Design: Simplified controls for easier operation.

 Blue – (Power Supply) – 3s Pulse

  Red – (RS 485) – Pulsating when signals are transmitted from the Master.

  Green – (RS 485)- Pulsating when speed, parity, and node settings match.

Comprehensive After-Sales Support

Demonstrating our confidence in the Sunmeter Pro’s performance and our commitment to customer satisfaction, we offer an unparalleled support package. This includes a complimentary recalibration service after one year of use, as well as immediate sensor replacement if its tolerance exceeds 3.5%. This guarantee provides peace of mind and ensures the continued accuracy of your measurements

Accessories

  • Pulse Anemomter
  • ENV METER
  • ENV PRO
  • ENV4
  • USB/RS485 interface cable
  • USB/MICRO-USB smartphone adapter
  • Sm configuration for Android smartphone and tablet SMCONFIG allows you to configure Sunmeter in the field from your Android smartphone. It is no longer necessary to bring the Sunmeter back to the laboratory for configuration.The software allows you to:
    • configure Sunmeter.
    • make a diagnosis of the basic functions.
    • log irradiance, temperature and wind (Sunmeter Wind only) readings.

    The software is available for free on this page in the downloads area. In addition to the software, a USB/RS485 converter and an adapter cable between microUSB/USB and a female M12 4-pin connector for the Sunmeter are required.
    In the Downloads area, you can also find a wiring diagram of our cable, which connects a smartphone, tablet, or PC to the irradiance sensor. This cable draws and converts the voltage supplied by the USB port (price available on request). Alternatively, other cables with an external power supply (such as a 9V battery) can be used.
