Wiring
Modbus TCP
- Connect the inverter's LAN port to your local network.
- Default port: 502.
- The Modbus unit ID must be set between 1–247 (default 1).
RS485
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.
| Device | SmartgridOne Controller model OM1 | SmartgridOne Controller model IG8 | RS485-USB converter | RS485-Ethernet converter |
|---|---|---|---|---|
| RS485-A | RS485 A | RS485_POS | RS485 A | TX+ |
| RS485-B | RS485 B | RS485_NEG | RS485 B | TX- |
| GND | RS GND | GND | Not available | G |
Serial settings:
- Baud rate: 9600 (default) or as configured in the inverter menu
- Data bits: 8
- Parity: None
- Stop bits: 1
Configuration
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.
- Set the Modbus address (slave ID) between 1–247 in the inverter menu.
- Each device on the RS485 bus must have a unique address.
- For RS485 wiring best practices, see the Wiring guidelines.
FlexAmp Series Setup
During device scanning or manual configuration, you'll be asked:
"What is included in the installation?"
- Solar panels and battery (default)
- Only solar panels
- Only battery
Select the option that matches your installation to ensure proper device detection and monitoring.
Control
Dysun Hybrid
The inverter supports battery control:
- Charge mode: Set charge current in amperes
- Discharge mode: Set discharge power as percentage
- When control is disabled, the inverter returns to autonomous operation
Caution
Experimental Control features for Dysun Hybrid have not been validated on live hardware.
