4) Push the threaded sleeve into the plug, screw the press nut tightly.
5) Finally, insert the AC connector into the corresponding AC receptacle on the inverter. Pay attention to the polarities
to make sure the correct assembling.

7.6 Wiring DC Input

Note: The DC connectors are in paired (negative and positive ones). Pay attention to the polarities when assembling.

7.6.1 Requirement for DC input

This single-phase inverter is equipped with two MPP trackers.
Requirements for PV module strings:
1) Same type PV modules for each string.
2) The power, voltage (startup and open-circuit voltage) and operating current of each PV strings must meet the
allowable value of the inverter.
Note: Consider temperature coefficient of the PV modules.
Check the inverter specification in section Appendix B.
