8.1 Prerequisites for commissioning
● All inverters in the system are connected with one another
via RS485.
● All inverters are supplied with AC or DC voltage.
● The PC is connected to the RS485 network of the inverters
via a USB/RS485 adapter.
● Commissioning the inverter requires a PC with the com-
missioning software and Delta Service Software (DSS) in-
stalled. You can download both at www.solar-inverter.com.
