Meteocontrol is one of the leading datalogger manufacturers for photovoltaic (PV) plants .
Data loggers record and analyze values such as irradiance, temperature, wind speed, and wind direction coming from the sensor. They are widely used to capture various data and environmental conditions and transmit this information to monitoring systems. In solar power plant projects, data loggers are essential for remotely monitoring plant performance and recording data. Bluelog is a data logger compatible with KACO inverters and many other brands. It records all relevant system data and provides various interfaces and functions for power plant management.
Although Blue’Log series data loggers are not manufactured by KACO, they are commonly used in GES projects where KACO inverters are installed as part of data recording and monitoring systems. Previously, KACO produced its own data loggers but later discontinued their production. Blue’Log data loggers are compatible with many inverter brands beyond KACO. The VCOM monitoring system is typically used alongside Blue’Log data loggers for monitoring purposes.
To effectively monitor PV power plants, a set of sensors compatible with the Bluelog data logger is required. SEVEN is a manufacturer of meteorological stations compatible with many data loggers used in PV power plant monitoring, and Bluelog is among these supported devices. Since the Bluelog data logger connects to the SEVEN Weather Station via an RS485 port using the standard MODBUS-RTU protocol, full compatibility is ensured.
Bluelog Weather Station Sensor Components:
Reference Cell Irradiance Sensor: Measures plane-of-array (POA) irradiance values. Structurally similar to a solar panel and rated as Class A.
Module Temperature Sensor: Measures the temperature on the back surface of the solar panel and sends data to the data logger.
Ambient Temperature Sensor: Measures the air temperature in the area where the PV panels are located, recorded in degrees Celsius (°C).
Wind Speed Sensor: Converts wind speed into an electrical signal to measure wind velocity. Its connection to the data logger is made via the SEVEN irradiance sensor.
Wind Direction Sensor: An analog output sensor that converts wind direction information into an electrical signal, commonly used in solar power projects.
VCOM Monitoring System
The Blue’Log X-Series data logger collects all data from the PV system, records all relevant system data, and offers multiple interfaces and functions for power plant management.
With VCOM (Virtual Control Room), you can easily and conveniently monitor the performance of your entire system portfolio worldwide at any time. In case of a fault, errors can be quickly detected and resolved efficiently.
Thanks to its graphical user interface, the data logger can be configured locally in the field or remotely via VCOM with ease and speed.
The VCOM monitoring platform provides detailed information on the performance of each module individually as well as the overall system, both historically and currently. This enables users to detect, locate, and solve faults, manage maintenance activities effectively, and analyze site efficiency.
SEVEN Sensor offers remote setup services through the VCOM platform. After completing all configurations and sensor registrations, meteorological data can be viewed directly on the VCOM monitoring system interface.
If you encounter any difficulties during installation, SEVEN Sensor engineers are available to assist you remotely. Should you prefer onsite support, our engineers can provide sensor mounting, installation, and configuration services at your site. We are committed to supporting you with any information or technical assistance you may need. For all technical inquiries or further information, please feel free to contact us.
