Sunmeter Pro Counter – Photovoltaic Pyranometer – Solar Power & Energy

Last update

SUNMETER PRO COUNTER is a irradiance (W/m2) and irradiation (kWh/m2) sensor. In fact, in addition to the normal irradiance measurement functions, there are totalizers that return the irradiation measurement. It is essentially a photovoltaic pyranometer used to measure solar power and solar energy:
  • IRRADIANCE = Power of sunlight in a given instant (W/m2)
  • IRRADIATION = Energy of sunlight for a period of time (kWh/m2)
Note: the terms irradiance sensor, photovoltaic pyranometer, reference cell and solarimeter are interchangeable. On this site we will use photovoltaic pyranometer. To learn more click here.

A powerful and accurate instrument to measure Performance ratio

At the heart of this irradiance and irradiation sensor is a photovoltaic cell laminated with an anti-reflective glass for photovoltaic modules. The advantages of photovoltaic glass, added to the high linearity and stability of our monocrystalline cell, improves the measurement accuracy for all possible sun inclinations taken during the day. SUNMETER PRO COUNTER allows an easier, more complete and accurate reading of the performances of a photovoltaic system. In addition, a special counter indicates whether there has been a re-ignition of the sensor: in this way it is possible to know whether the meter indicates a reliable measurement or not, over the measured time. To be used effectively it is important that the data logger stores the readings and the value of the energy produced by the photovoltaic system at the end of each day. This allows comparison of the energy produced and the irradiance received and accurate calculations of P.R. for each day. This PV reference cell is a product intended for System Integrators and monitoring system manufacturers who can use the measurements and readings ​​in their own scripts and programs.

Accessories

  • Temmeter

  • 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 it is necessary to have a USB / RS485 converter, an adapter cable between microUSB/USB and a female connector M12 4 pin for Sunmeter. In the Download area you can find a wiring diagram of our cable that connects Smartphone/Tablet or PC with the irradiance sensor, it takes and transforms the voltage present on the USB (Price on request). Alternatively, it is possible to use other cables with external power supply (9V battery).
