Connecting the sensors
· 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.
