Soluzione SM1-485PRO solar meter, radiometer

The Soluzione SM1-485PRO is a professional solar radiation meter (pyranometer) specifically designed for the accurate measurement and analysis of photovoltaic system performance. The device features digital RS485 Modbus communication, making it easy to integrate into monitoring systems, particularly for medium and large-scale solar power plants.

What is the SM1-485PRO used for?

The device’s primary function is to measure solar radiation (irradiance) and the energy derived from it (irradiation), which is essential for evaluating the performance of solar power systems . Sensors of this type are typically used to calculate the Performance Ratio (PR), one of the most important indicators of a system’s efficiency.

This makes it possible to:

• comparing power output with solar radiation
• identifying faults and performance declines
• accurate yield calculation

Advanced measurement functions

The SM1-485PRO is not just a simple irradiance sensor, but also features advanced counting functions. The device uses several different measurement counters that calculate the time-integrated solar radiation energy (Wh/m²).

Main measurement functions:

• total irradiation counter
• threshold-based energy counter
• measurement linked to external conditions
• restart counter (power outage detection)

This is particularly useful for long-term monitoring and statistical analysis.

SOLARKIT reviews

The Soluzione SM1-485PRO falls squarely into the “professional-grade device” category: it is not designed for residential monitoring, but rather for the precise measurement of more sophisticated systems. Its major advantages are the built-in counter logic and Modbus communication, which enable deeper data processing and analysis.

It is highly recommended for projects where:

• accurate PR calculation is important
• production validation is required
• or bank/investor-level monitoring is performed

Overall, it is a stable, industrial-grade radiation meter that provides real added value to system monitoring.
