1 year ago I don't think the system is suitable at all for your system, there are only 2 clamps for 2 phases, and the system expects 2 phases out of phase by 180 degrees, while a 3-phase system is out of phase by 120 degrees, so I think you will get bad values anyway. Even if the module used for the measurements can be configured for such type of application, at least you need to change the firmware. Which transformer are you using?

I have a simular question. Have 230V 50Hz but three phases. Done the configuration but can´t get the voltage calibration right. Jameco 9VAC Transformer: For meter versions: >= v1.3: 7305
voltage_cal: '7305'
This setup is for 120V transformer. Around what value should be used for 230V transformers? When I turn this all the way up to 65535 I get a reading around 13V i Home Assistant. And if I use 7305 I get around 0,3V.

Hi, I bought the solar kit, and I realized that is designed for a two-phase system after purchasing it, while in my country I have a single-phase grid supply at 230V 50Hz (1 phase + neutral), and I would like to know if I should be able to configure the system anyway using only the standard calibration, and without installing the CT2 and the SCT2 clamps, or I need to change the code and recompile it.
Have you any hint for such type of configuration??
