Data acquisition

In recent years, huge investments have been made in the solar energy industry. Now this sector has entered a new phase, where the emphasis is on optimization. PV-facilities are now being operated and managed so that they deliver maximum output. This is not only financially interesting but also adds to the sustainability of the industry. An advanced monitoring system is an absolute necessity for optimization of PV plants. The basis of the data logger is a modular PLC to which I/Os can be connected to communicate with inverters, sensors and other components in an installation. The PLC communicates via a fixed, mobile internet or satellite connection – depending on the application – with a secure server.   The users can log in on this secure server to consult and analyze the data of its PV plants by means of a password protected login.
To assure quality, reliability and flexibility, we resolutely opted for a solution with industrial components by Phoenix Contact, global leader in industrial automation.

Features

Decentralized, modular concept Solution can handle commercial, industrial and utility scale projects.
Robust solution Mind4Energy uses industrial quality PLCs. These devices are also used in industrial automation applications and are more robust then PCs. For instance a PLC can resist peak electrical conditions (voltage peaks and dips) and can operate in a wider temperature range (-25 °C .. 55°C). The different readings are brought straight to the PLC without additional converter units.
Flexible solution I/O cards can be added in function of the project needs.
Memory 20 days local memory for data storage in case of transmission problems.
Optional components • UPS and battery
• 3G/4G modem or router with VPN capability
• Fiber optic capability
• Satellite communication can be included
• Integration of CCTV is possible
Meteo stations Meteo stations are integrated. The sampling methodology is approved by the sensor manufacturer and can be adjusted according to the client’s requirements.
Energy meters Energy meters and power analyzers can be integrated. AC-side monitoring is possible.
Power control Data logging (reading) and writing (control). The system is capable of receiving net operator signals for power control of the inverters.
Mind4Energy SCADA Possibility to connect to local Mind4Energy SCADA.
VPN / GUI Mind4Energy provides secure remote access to the PV site. Datalogger settings can be checked / changed remotely using the Mind4Energy Graphical User Interface (GUI).
