HUAWEI - Single-Phase 100A Meter

The Huawei DDSU666-H Smart Power Sensor is a single-phase (1P2W) current transformer energy meter designed for monitoring residential photovoltaic systems equipped with Huawei single-phase inverters (particularly the SUN2000-KTL-L1 series). It measures consumption, production , and grid injection via a 100 A / 40 mA current transformer supplied with a 5 m cable.

Its class 1 accuracy (+/- 0.5% in voltage, +/- 1% in current/energy) and RS485 communication via Modbus-RTU (9600 bps) ensure native integration with the FusionSolar platform through the SUN2000 inverter. The LCD screen allows for direct viewing of parameters on site.

Its DIN35 rail mounting, dimensions of 100 x 36 x 65.5 mm, and weight of 1.2 kg make it the most compact measurement sensor in the Huawei range. Its power consumption is less than or equal to 0.8 W. The phase voltage measurement range covers 176 to 288 Vac, and the current from 0 to 100 A via the included current transformer. A 10 m RS485 cable is included. Operating temperature range: -25 °C to +60 °C, humidity 5 to 95% RH.
