Sungrow Smart Energy Meter Application Guide

The Sungrow Smart Meter presents a clear overview of energy consumption in combination with Sungrow iSolarCloud. The Sungrow Smart Meter is ideally suited for use with the Sungrow single-phase inverter and three-phase string inverters.

Note: The measurement range (primary current) of the current transformer should be selected according to actual maximum current at the grid-connected point, and the maximum secondary current of the current transformer should be 5A. The CTs shown as below are only suggestions for customer.
