For installing the S100 (Smart Energy Meter) to the 1-Phase Hybrid inverters, the COM 2 port will be used and connected to the grid as follows:
Pass the Power Phase Cable from the grid through the meter´s CT (current transformer) for it to measure the current flow. The communication cables A and B will communicate the meter device to the inverter.
From the Smart meter device, the Grid´s Neutral (N) and Phase (L) cables are used to measure the Phase Voltage (L-N).
