The Sigen Power Sensor Three Phase External CT is a smart three-phase meter from Sigenergy, designed for the SigenStor modular energy storage system. The current transformers (CTs) supplied enable current measurement of up to 100 A per phase – ideal for real-time monitoring of energy flows in domestic and commercial installations. Thanks to Modbus RTU communication, 100 ms data refresh rates and DIN rail mounting, the sensor is easy to install and integrate into existing systems. The high measurement accuracy of up to 1% ensures precise control and optimised energy distribution.
