Product Description

WS50PV Compact all in one weather sensor

The WS50PV (8373-PV) is an affordable, compact all-in-one weather sensor measuring the most critical parameters for commercial and industrial PV monitoring. Equipped with a suite of professional measuring sensors, the WS50PV can handle air temperature, relative humidity, barometric pressure, wind direction, and wind speed in one efficient housing to simplify mounting. Add an external temperature or rain sensor to the single-wire digital Modbus interface for fast and easy integration. The WS50PV is the tool you need for unlocking solar energy performance.

Application: • Commercial PV monitoring • Industrial PV monitoring • Building Automation.


Added confidence for energy production PV site performance analysis is strengthened by correlating air temperature and wind speed with PV panel temperature data. The increased context of power production data offers peace of mind to ensure the solar system is meeting expectations as well as enabling more accurate alarms to be setup to detect system failures.

Reliable Accuracy: Data you can count on – ISO/IEC compliant with a lifetime expectancy greater than 10 years.

Hassle-free data: Focus on power generation, not sensor installation and maintenance. Five parameters combine in one housing, mount, and cable with a single digital output to any Modbus RTU-ready data acquisition system.

Modular: Easily add a precipitation or back of module temperature sensor to the same Modbus ID.
