Configuration
waarschuwing
Inverters with firmware version older than the following have a minimum SoC level of 35%. Starting from this version, this setting can be configured by the user.
Minimum required version: MCU version 1040, DSP version 1042.
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.
