Hi, I know most things designed for single phase, (230v one hot, one neutral, one ground) will work OK on split phase (two 110 lines and ground) although some things designed for US type 220v split phase won't work on 230v single phase. I need to use a 230 volt single phase zero export controller on my 220 volt split phase (US type) system. Does anyone know if something like that would work OK. It senses the voltage/amperage flowing from/to the utility and regulates the output from the solar. We are in The Philippines but we use the US style split phase.
