WS50PV: Compact All-in-One Weather Sensor

The WS50PV from Kipp & Zonen is a small-sized, cost-effective, multipurpose weather sensor that can measure the most crucial parameters for industrial and commercial PV monitoring.

The WS50PV sensor is fitted with a range of professional measuring sensors, which enable it to measure relative humidity, air temperature, wind direction, barometric pressure and wind speed in a single efficient housing to streamline mounting.

Users can integrate an external rain or temperature sensor to the single-wire digital Modbus interface for quick and simple integration. The WS50PV is the most sought-after tool for unlocking solar energy performance.

Applications

  • Building automation
  • Industrial PV monitoring
  • Commercial PV monitoring

Benefits

Added Confidence for Energy Production

The analysis of a PV site’s performance is reinforced by correlating wind speed and air temperature with PV panel temperature data. The enhanced context of power production data provides peace of mind to guarantee that the solar system meets expectations and facilitates the setting up of more accurate alarms to identify system failures.

Hassle-Free Data

Users can focus on power generation instead of sensor installation and maintenance. Five parameters integrated into a single housing, mount and cable with a single digital output to any Modbus RTU-ready data acquisition system.

Reliable Accuracy

Users can count on the data provided by the sensor since it is ISO/IEC-compliant with a life expectancy of more than 10 years.

Modular

Users can simply add a back-of-module or precipitation temperature sensor to the same Modbus ID.
