Litemeter Voltage Pro – Analog Irradiance & Temperature Sensor

Last update

Litemeter Voltage Pro is a analog photovoltaic pyranometer (or silicon irradiance sensor) for measuring solar irradiance and temperature, ideal for monitoring medium-sized photovoltaic systems. Manufacturing and calibrations are IEC 61215, IEC 60904-2, 60904-4 and 60904-10 compliant. Litemeter Voltage Pro product is ABB approved for stringboxes, EVO dataloggers and for some inverter models.

Physical features

The Silicon photovoltaic cell is laminated with E.V.A. and a high performance anti-reflective glass for photovoltaic modules. It guarantees the maximum precision in the measurement of irradiance and provides a measurement of the indicative temperature of the photovoltaic modules next to it. It has an anodized aluminum housing for high durability, practical mounting bracket with screw clamp and a UV-resistant cable. This irradiance sensor has two signal outputs in voltage: one for solar irradiance and one for temperature. The solar irradiance signal is temperature compensated; allowing readings that are independent of cell temperature.

Calibration

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