Shihlin protocol and Modbus protocol

If any communication parameter is changed, please power off and restart inverter.

SC3 series inverters offer two protocols to choose from: Shihlin protocol and Modbus protocol. Parameters
07-02(P.32), 07-01(P.36), 07-08(P.52), 07-09(P.53), 07-10(P.153) are for both protocols. Parameter
07-03(P.48)~07-06(P.51) only applies to Shihlin protocol and parameter 07-07（P.154）applies only to Modbus
protocol. Please refer to communication protocol for details.
