If more than two strings are required, they can be connected in parallel in an
external combiner box before connecting a unified DC connection to the inverter.
NOTE:
Due to the SolarEdge architecture, the parallel strings may be of different lengths
and therefore do not necessarily need to be connected to an identical number of
power optimizers.

Completing the Inverter Installation

After completing all connections, the inverter must be activated. Refer to the
activation instructions supplied with the inverter.
In most cases, the inverter is preconfigured before delivery. After activating the
inverter, you must verify that the inverter is configured to the proper country,
as described on page 72.
If not, then you must configure the inverter to the site's requirements using the
inverter's internal buttons or by using the SolarEdge Configuration Tool
connected to an RS232 or USB port. For more information, you may refer to the
Configuring the Inverter Using the LCD Panel and User Buttons section on
page 67.
