Huawei SmartPS-100A-S0 Single-Phase Meter Kit Smart Power Sensor 100 A with CT
The Huawei SmartPS-100A-S0 is the commercial code of the single-phase Smart Power Sensor kit consisting of the DDSU666-H meter and the YDS70-C16 100 A / 40 mA split-core current transformer. It is used to measure the grid connection point in single-phase photovoltaic and storage systems with Huawei SUN2000 inverters.
It is mounted on a 35 mm DIN rail inside the distribution board and connected to the inverter via RS485 Modbus-RTU. The split-core CT is clamped onto the phase cable without cutting it. It supplies the inverter with the active power, imported energy and exported energy data needed for optimised self-consumption, export limitation and monitoring in the FusionSolar app.
Key features
Complete kit: meter + CTIncludes the DDSU666-H meter and a YDS70-C16 100 A / 40 mA split-core current transformer.
Single-phase measurement 0.5 – 100 ACovers the entire current range of single-phase domestic installations, with bidirectional reading of import and export.
Accuracy class 1Accuracy of ±0.5 % on voltage and current, ±1 % on power and energy.
Integration with Huawei invertersRS485 Modbus-RTU communication with SUN2000 inverters for self-consumption, load control and zero feed-in.
Quick installationModular format for a 35 mm DIN rail and a split-core CT that does not require existing cables to be cut.
Negligible consumptionSelf-consumption below 1.5 W and operation from −25 °C to +60 °C.
