Wiring​

The SmartgridOne Controller and the ESY inverters communicate via RS485.

Configuration​

attention

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.
