5.5 DC input mode in parallel for three phase inverters
For the connection of only one DC line on 2 inputs, compatibly with electrical
features, it is recommended the conguration of inputs in parallel. For this
connection mode it is suggested to use Y-wires as in diagram. There are no
display settings available for parallel connection of strings.
