5. In the case of Bifacial modules, the screen of Fig. 54 is present on the display. The
following parameters are shown:
➢ VPN voltage between positive and negative pole of the string
➢ Module temperature (with PT305 probe connected)
➢ Irradiance of the front side of the module measured by reference cell HT305
➢ Irradiance of the back side of the module measured by reference cells HT305
The "Rear Irradiance” parameter indicates the minimum value between the
irradiance measured by the HT305 cells at the bottom back (BB) and top back
(BT) of the module
➢ Display of currently selected PV module
➢ References of C1, P1, C2, P2 terminals connected to the instrument

shown in Fig. 55. The following parameters are given:
➢ Voc and Isc (@STC) references of the currently selected module
➢ Parameters of the test string to be programmed
➢ Icon to save the settings and return to the main screen, or icon to exit
