Appendix C Power frequency & PV switching solution
C.1 Solution introduction
Generally, inverters do not allow simultaneous connection of power frequency and PV. If
such simultaneous connection is required, switching control circuit needs to be
configured externally. The following figure shows a solution for reference.
