Litemeter Voltage Pro is an analog photovoltaic pyranometer for measuring solar radiation 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 performing antireflective 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.

Litemeter Voltage Pro 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 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

Its reliability and precision make Litemeter Voltage Pro suitable for monitoring medium-sized systems.
