Sunmeter PRO is a digital photovoltaic pyranometer (or silicon irradiance sensor) for calculating photovoltaic plant performance with a high degree of precision and reliability. Its monocrystalline silicon cell is laminated with glass for photovoltaic modules and E.V.A. like a micro PV module. It has additional stabilization processes and tests to minimize measurement drift over time. The cost includes a recalibration service after one year as well as the immediate replacement of the irradiance sensor if tolerance exceeds 3.5%.

Sunmeter PRO Certified is a digital photovoltaic pyranometer (or silicon irradiance sensor) calibrated by Fraunhofer ISE(DAKKS accred.). A digital photovoltaic pyranometer (or solar irradiance sensor) for calculating photovoltaic plant performance with a high degree of precision and reliability. This digital photovoltaic pyranometer consist of a monocrystalline silicon cell which is laminated with a glass usually used for photovoltaic modules and E.V.A. Our Irradiance sensor has an additional stabilization processes and tests to minimize the measurement drift over time.

Sunmeter PRO Sunspec is based on Sunmeter PRO, a digital photovoltaic pyranometer (or silicon irradiance sensor) for calculating photovoltaic performance with a high degree of precision and reliability. This SUNMETER also has a SUNSPEC prescribed Modbus mapping. Like the Sunmeter PRO, the PRO SUNSPEC has a cell laminated in glass that increases the durability and stability of measurements over time; the microprismatic glass is the same glass used in photovoltaic modules. This irradiance sensor, thanks to a precise production process, has a performance decline of less than 1.5% per year.

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:

It is equipped with electronics to amplify a very weak signal coming from the thermopile, and mounted with the best operational amplifiers on the market in terms of linearity, noise immunity, consistent behavior over time and in temperature variations. The signal is normalized in the range 4 to 20mA. This analog output mode of the signal (current loop) is characterized by a simple wiring (cable with 2 wires), and a high immunity to electromagnetic interference and interference caused by distances of over ten meters.

It has a simpler construction than the Class B, but uses the same high quality materials. As the Class C is equipped with the same electronics as the Class B, the signal has a high level of linearity and noise immunity. The signal is normalized in the 4 to 20mA range. This analog output mode of the signal (current loop) is characterized by a simple wiring (cable with 2 wires), and a high immunity to electromagnetic interference and interference caused by distances of over ten meters. This instrument is suitable for measuring solar power and monitoring the efficiency of photovoltaic systems when a precision of 5% – 10% is sufficient.

The PYR1-485 is equipped with the electronics board with a microcontroller to manage sampling, average of sampling, temperature reading and RS485 transmissions. This helps to guarantee noise immunity  and constant behavior over intervals of time and temperature variations. The output signal is in ModbusRTU over RS485. The carefully selected components have a constant behavior over time and for a wide temperature range. The distances covered by the signals exceed 500 meters.

The PYR2-485 is equipped with the electronics board with a microcontroller to manage sampling, average of sampling, temperature reading and RS485 transmissions. This helps to guarantee noise immunity and constant behavior over intervals of time and temperature variations. The output signal is in Modbus RTU over RS485.

Litemeter Modbus PRO is a digital photovoltaic pyranometer (or irradiance sensor) equipped with a monocrystalline silicon cell. Manufacturing and Calibrations are done following the IEC 61215, IEC 60904-2; 60904-4; 60904-10 regulations. The silicon photovoltaic cell is laminated with E.V.A. and a high performance anti-reflective glass for photovoltaic modules. It guarantees a fair precision in the measurement of irradiance and provides a measurement of the indicative temperature of the photovoltaic modules next to it. This irradiance sensor has an RS485 bus interface, using the well known industry standard protocol Modbus RTU.

Litemeter Current Pro is an analog photovoltaic pyranometer (or irradiance sensor). It is equipped with a monocrystalline silicon cell for high efficiency, and temperature compensated output. Manufacturing and Calibrations are done following the IEC 61215, IEC 60904-2; 60904-4; 60904-10 regulations. This irradiance sensor is the laminated glass version of the Litemeter Current sensor. The cell is laminated with a high performance anti-reflective glass for photovoltaic modules and E.V.A. The current output 4-20mA allows the analog signal to remain unchanged in cases whereas the distance between the sensor and the control unit is 10m and more, or in disturbed areas. Distance up to 20-35m are attainable if there’s no signal interference.
