RK900-01 is an automatic weather station for photovoltaic plants designed to monitor in real time the environmental conditions that affect solar installation performance and operational safety. The system integrates high-precision meteorological sensors, a data logger, and IoT communications for continuous data acquisition, analysis, display, storage, and transmission.
According to the manufacturer, the solution is intended for solar parks and PV applications where critical environmental parameters must be recorded to optimize energy efficiency, supervise field behavior, and maintain reliable operating history. Key features include high accuracy, strong resistance to harsh environments, convenient data download, automatic storage and backup, optional solar power supply, and robust all-metal mounting construction.
The configuration can include a meteorological data logger with computational analysis, 7-inch LCD screen, and local history download; RS485, 4G, WiFi, or Ethernet communication gateway; sensors and cabling for wind, temperature, humidity, and solar radiation; multilayer radiation shield; protective box for the logger, battery, and electronics; optional solar power system; and vertical mast with lightning protection.
Declared applications: agriculture, solar photovoltaic industry, hydrological monitoring, highways and railways, meteorological research, and outdoor environments.
