· Optional irradiation sensor

The optional addition of an irradiation sensor (type Si-01TC-T from Ing.-Büro Mencke & Tegtmeyer ) with integrated PT-100 temperature sensor for tempera- ture measurement enables recording of the irradiation data and the correspon- ding module temperature in the cycle of the internal data memory.

This additional measuring unit helps with analysis of the system. On the basis of the values, possible errors in the PV generator, such as e.g. shading or failure of solar cells, can be detected.

For demonstration purposes, the irradia- tion sensor and the corresponding data can be used to show how a PV system functions. In conjunction with the Sunways NT Monitor visualisation soft- ware, the stored data can be displayed.

Before you connect an irradiation sensor, you must remove the cover of the solar inverter. Pay heed to all safety hints on pages 90 and 91. Please note that the inputs and outputs are not short-circuit resistant.

The optional irradiation sensor with temperature sensor is connected to the corresponding terminals at the bottom right of the middle board.
