Technical Support

I need to install an external meter with RS-485 communications at the grid connection point for a system with a Sunsynk 16KW Max inverter. The AC supply cable is too large for a "pass through" meter such as the CHNT / Eastron SDM230 to be used as referred in the SunSynk manual. I need to use a meter with an external CT. Does anyone know of a meter like this which is compatible with the SunSynk Max 16 K ?
