摘要 |
A photovoltaic (PV) sub-generator junction box (1) for a PV system (100) comprises a plurality of electric terminals (11) for optionally connecting one respective PV string (2) of one or more serially connected PV modules (3). Said PV sub-generator junction box (1) further comprises a sub-generator line terminal (12) for connecting a PV sub-generator line (4) of a remote central PV inverter (5) or connecting a PV sub-generator line (4) of an inserted PV generator junction box (6). The PV sub-generator junction box (1) also comprises an electronic control unit (10) that is connected to a central control unit (7) of the PV inverter (5) in order to exchange data (DAT0). According to the invention, the PV sub-generator junction box (1) comprises a power line modem (8) for feeding and retrieving the data (DAT) via the PV sub-generator line (4). |
