Wiring

RS485

For RS485 Wiring, use the Reserved Communication port (N° 14) on the inverter.

Info
RS485 Wiring
  • For correct RS485 wiring: Follow the guidelines for RS485 wiring.
  • If the wiring shown in the table below is incorrect, please let us know.
  • There is no general consensus in the industry about the usage of A and B for the RS485 polarity, so it may be counterintuitive and opposite of what you might expect for some devices.

Warning
NOTE: RS485 Device Addresses
  • You MUST give each device on the RS485 bus a unique address. Check the manual of the device on how to do this.
  • Use lower addresses first (1, 2, ...) because the SmartgridOne Controller will find them faster!
  • For each device, it is generally recommended to stick with the factory default baud rate, parity, and stop bits. The SmartgridOne Controller will scan on those first.
