Sigenergy Sigen Power Sensor TP-CT600-DH Three-Phase Energy Meter with 3 CTs 600 A
The Sigenergy Sigen Power Sensor TP-CT600-DH is the three-phase energy meter with three 600 A split-core current transformers for commercial and industrial photovoltaic and storage systems based on Sigenergy equipment. It measures voltage, current and power on the three phases and records bidirectionally the energy drawn from the grid and the energy fed into it.
It is installed on a 35 mm DIN rail in the panel at the connection point and communicates with Sigenergy devices via RS485 Modbus RTU, with no need for special configuration. The split-core CTs are fitted onto the existing phase conductors without interrupting the installation, making installation safe and quick even on large cross-section lines. The 100 ms data refresh enables fast export limitation, peak shaving and load balancing functions.
