Fig. 8-3-3 - 4 Connect the RS485 card
(several photovoltaic solar inverters)
In the case of several photovoltaic solar inverters, the RS485 bus is looped
through the individual photovoltaic solar inverters. The bus cables D-, D+ and
GND (incoming and outgoing) are connected in parallel to the screw
connectors on the Rs485 card. The screening on the bus cables should each
only be connected at one end with the PE on the photovoltaic solar inverter
housing.
