I can't find my Ampihome inverter For Ampowr hybrid inverters, the default bus addresses are 247 for Modbus RTU and 255 for Modbus TCP. The SmartgridOne Controller will scan for devices on all addresses from 1 to 255. Therefore, it can take a while to scan for devices.
TIP: If you know the bus address of your inverter, you can set it in the SmartgridOne Controller to speed up the scanning process.
The Ampihome Single-Phase needs to be set to Slave Secondary Port:
