You can connect 1 outside temperature sensor and 1 module temperature sensor to the

Cluster Controller. The measured values of the temperature sensors are shown on the display and the

user interface of the Cluster Controller and transmitted to Sunny Portal. In Sunny Portal, the measured

values of the module temperature sensor flow into the calculation of the performance ratio.
