3.3 Communication with the inverter

3.3Communication with the inverter

Various possible methods of communicating with the inverter are presented below.

3.3.1WEB’log

WEB’log is generally used to log inverter data, i’checker data and meteorological data which has been recorded while the inverter is in operation. This data can be represented graphically in an Internet portal. In systems with WinCC, WEB’log serves as an interface for the i'checker sensors.

3.3.2WinCC

The description of functions and directions for use of WinCC can be found in a separate document.

By selecting button "New" in the main menu, you can access the screen for entering the names of the connected SINVERT units. You must enter the relevant names (up to maximum 40 characters in length) in the box "SINVERT name". The slave addresses are automatically incremented from 0 to 31, which means that you can register up to 32 SINVERT inverters in this program. The maximum permissible length of data cable to the local PC is 100 m. Up to four SINVERT units can be displayed at one time. If more than four are displayed, the transmission rate decreases significantly.

By double clicking on the name of an inverter, you will branch to submenus System Diagram, Control Panel, Oscilloscope, Process Data, Data Storage, etc. Double click on one of these to open the relevant window.

The System Diagram (Figure 3-5) shows the entire PV plant, including the PV generator, DC contactor, inverter, AC contactor and grid interface. The status of the system components and the energy flow within the system are represented by different colors in the diagram.
