Install PV connectors
Step 1
Confirm that all DC switches on the inverter (shown Figure3-41) are OFF.

Diagram of DC switch OFF status
Step 2
Check whether the polarity of the PV string is correct and ensure that the open-circuit voltage in any
case not exceeds the maximum input voltage of the inverter 1500V.

Step 3
Insert the positive and negative connectors into the MPPT "+" and "-" terminals on the bottom of the
inverter respectively (as shown in Figure3-43). When you hear a click, it means the connection is
completed.

If any PV connector on the inverter is not connected to PV string, block it with original plug.
