2. Parameter Settings

  • Communication Parameters: Set F8.00 (local address), F8.01 (RS485 communication baud rate setting), F8.02 (RS485 data format setting), etc., to ensure normal communication between inverters.
  • Multi-Pump Networking Mode: Set F0.20 (multi-pump macro debugging function) to select the corresponding multi-pump networking mode (e.g., master, slave, etc.).
  • Network Mode: Set F1.02 (multi-pump network mode selection) to define the network role of each inverter (e.g., master, slave, etc.).
  • Slave Settings: Set F1.00 (multi-pump networking communication address) on the slave to ensure each slave has a unique address.
  • Other Parameters: Set the number of multi-pump networking slaves (F1.03), multi-pump operation mode (F1.04), etc., according to actual needs.
