Sigenergy TP-CT100-WI (three-phase CT sensor)

The TP-CT100-WI is a three-phase smart meter sensor for SigenMate and compatible Sigen systems. It uses 100 A current transformers to measure energy flow at the grid connection point and provides data for monitoring and import/export limiting.

The sensor measures voltage, current, power, frequency and energy flow in a three-phase network, with a stated data update interval of 100 ms. Stated accuracy is 1 % for power, 0.5 % for voltage and current, and 0.2 % for frequency. Connectivity is 2.4 GHz Wi-Fi, Bluetooth LE for setup, and RS485 for wired connection. The stated measurement range in three-phase four-wire wiring is 100 to 277 V phase-to-neutral and 173 to 480 V phase-to-phase.

The unit is designed for mounting on a 35 mm DIN rail in the distribution board. Connection of L1, L2, L3, neutral, the current transformers and protective devices must follow the manufacturer's instructions. After installation, the sensor is added to the matching system in the mySigen app. The package includes one TP-CT100-WI sensor with 100 A current transformers.
