Description

The economic efficiency of the solar power system is determined by the yield that the system achieves daily from the solar energy. StecaGrid inverters allow these values to be called up and evaluated at any time. These functions make complete, integral monitoring of the solar power system possible.

Data logging

In order to gain a simple overview of the system performance, the voltage, current and power of the modules as well as the grid frequency and grid voltage are measured within the inverter. The energy yields from both the master and the slaves are also stored on a daily, monthly and annual basis. These measured values as well as the operating states of the StecaGrid system can be read on the user-friendly display.

Data communication

The option of downloading the data from the StecaGrid system using software and a StecaGrid Connect network card and processing it with a PC is also available. This means that it is not only possible to view the stored data, but it can also be transferred to the user’s PC in a clearly structured format and analysed as required. Of course, pre-prepared graphic illustrations are also possible with this programme. The corresponding software – which is supplied free of charge – is available in a version for system operators as well as in a version for installers. On the one hand, this distinction protects system operators (users) from deliberately or unintentionally manipulating their own systems. On the other, the installers (service provider) is given the opportunity to make necessary changes quickly and accurately, even over long distances. This ensures seamless and timely service.

Monitoring

If the inverter is connected to a fixed internet connection, the data can be viewed from any location via the StecaGrid Connect and the associated password using a web browser or StecaGrid Connect User. This means that the system can be observed anywhere in the world at any time. Of course, you can also use this opportunity to present your own PV system and impressively demonstrate its functionality and yields. This is made possible by providing special HTML pages. All values stored by the inverter are displayed there. Both current performance and past yields can be accessed quickly and flexibly. In order to guarantee the highest level of security at all times, access to these personal HTML pages is password protected.
