Sigenergy Sigen Power Sensor 3F CT120

Sigenergy Sigen Power Sensor CT120 three-phase 

The Sigen Power Sensor TP-CT120-DH is a high-precision three-phase energy meter with three external current transformers, designed for detailed measurement of current flows in high-performance photovoltaic or energy storage applications. It has been specially designed for use with Sigenergy system components such as the Gateway, SigenStor or Wallboxes. It enables reliable load monitoring for dynamic energy management – either locally or via the Sub1G wireless module.
