The Zendure SmartMeter 3CT-S is an intelligent three-phase energy meter developed specifically for dynamic power control of Zendure SolarFlow systems. It records the supply to the grid and the supply of the entire household in real time and transmits the consumption data directly to the energy storage system. The discharge and charging power of the storage is then adjusted with precision to current own consumption in order to maximise self-supply and prevent uncontrolled power infeed. The split-core current transformer (3CT) provided means installation in the fuse box is particularly easy with no need to disconnect the power lines. Special features
