SM1-485PRO-SUNMETER PRO

(SM1-485 PRO) is a high-tech electronic device primarily designed to accurately measure solar radiation, equipped with the VSN700 management system. It is intended primarily, but not limited to, be used in solar energy conversion applications (both thermal and photovoltaic) for preliminary studies, commissioning testing, and continuous performance monitoring.

The device relies on a monocrystalline photovoltaic cell element that, through TZOS® (Zero Ohm Shunt Technology), is sampled and managed by a high-performance Digital Signal Processor (DSP) to enhance signal precision and stability, achieving results comparable to the best-in-class radiometers.

It is equipped with an additional input for an external 2-wire PT100 RTD element to detect the temperature of nearby items, such as photovoltaic modules and the environment. Measurements can be read through a powerful, versatile EIA/TIA-RS485 bus interface with the well-known Modbus RTU industrial standard protocol and SUNSPEC mapping.
