STR-21G-S0 Solar Monitoring Systems:

A solar monitoring system, such as the STR-21G-S0, is designed to monitor and track the performance of a solar power generation system. The STR-21G-S0, manufactured by Eko, is a highly accurate and reliable monitoring system that is well-suited for use in a wide variety of solar power applications.

The system includes a number of different components that work together to provide detailed and real-time data about the performance of the solar power system. One of the key components of the STR-21G-S0 is the data logger, which is responsible for collecting and storing data from the solar panels, the inverter, and other key components of the system. This data is then transmitted a cloud-based monitoring platform, where it can be viewed and analyzed by the system owner and other authorized users.

One of the key advantages of the STR-21G-S0 is its high accuracy. The system uses high-precision sensors to measure various parameters, such as solar irradiance, module temperature, and current, voltage and power. The system also includes multiple communication options like Ethernet, Wi-Fi, and 3G/4G modems, which allows it to easily connect to other devices and systems, such as energy management systems and weather stations. The system is fully compliant with industry standard protocols such as Modbus TCP.

Another advantage of the STR-21G-S0 is its ease of installation and use. The system is designed to be straightforward and user-friendly, with a simple and intuitive interface that makes it easy for users to navigate and access the data they need. The system also includes a range of built-in safety features, such as overvoltage protection, to help protect the solar power system and its components from damage.

Overall, the STR-21G-S0 solar monitoring system from Eko is a high-performance and reliable monitoring solution that is well-suited for a wide range of solar power applications. Its high accuracy, ease of use and installation, and wide range of features make it an excellent choice for anyone looking to monitor and optimize the performance of their solar power system.

The STR-21G-S0 is designed to perform the most accurate measurements of direct solar radiation. Compatible with almost all DAQ systems and featuring multiple analog and digital inputs, the STR-21G-S0 is equipped with an internal sun position sensor and GPS receiver for quick and easy set-up.

Based on the STR-21G Sun Tracker, in combination with the Class A MS-57 Pyrheliometer, the STR-21G-S0 system can be freely configured to measure the required solar radiation components in the most accurate way. The MS-57 has a heated front window to avoid condensation and ice, which can affect the measurements, ensuring uninterrupted accuracy, whatever the weather.
