The Sigen Power Sensor Three Phase External CT 100A DH is a smart energy monitoring device designed to measure and track electricity flow in three-phase systems. It provides real-time insight into how much power is being consumed or exported, making it especially useful in solar and battery installations.
It works by using external current transformers (CT clamps) to detect the flow of electricity on each phase, then processes and communicates this data to connected energy systems. This allows users to monitor usage, optimize energy consumption, and improve overall system efficiency.
The sensor is built to integrate seamlessly with Sigenergy systems, enabling advanced energy management features such as intelligent control of power flow, import/export limitation, and automated optimization. It plays a key role in ensuring that energy systems—whether residential or commercial—operate efficiently, reliably, and in a cost-effective way.
