Litemeter Modbus PRO is a digital photovoltaic pyranometer (or solar 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 performing 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 sensor has a RS485 bus interface, using the well known industry standard protocol Modbus RTU.

Calibration

All Litemeters are calibrated with our Class A Silicon Reference Cell, itself periodically calibrated by the Dakks accredited Fraunhofer Institute in Germany and a HP34410A Multimeter.

Common uses

Litemeter Modbus Pro is ideal for monitoring and managing photovoltaic systems of up to a few hundred kW. It is useful where the monitoring system has RS485 input channels and a high accuracy in performance calculation is not required.
