Frequently Asked Questions
What is the Huawei Smart Power Sensor SmartPS-250A-T0?
The Huawei Smart Power Sensor SmartPS-250A-T0 (manufacturer designation DTSU666-H 250A/50mA) is a three-phase energy meter that records the current flow between the grid, PV system, and consumers. It enables zero feed-in, optimization of self-consumption, and precise system monitoring.
Which systems is the Smart Power Sensor suitable for?
The sensor is designed for three-phase systems (3~) with a 400 V grid connection and a primary current of up to 250 A per phase. Due to indirect measurement via current transformers, it is suitable for high-performance photovoltaic and storage systems.
How does the sensor communicate with the inverter?
Data transfer takes place via RS485 using the Modbus-RTU protocol. This way, measured values for consumption and feed-in are transmitted to the inverter in real-time and used for system control.
How is the Smart Power Sensor mounted?
The compact housing with dimensions of 100 x 72 x 66 mm (H x W x D) is mounted on a top-hat rail or DIN rail in the meter cabinet or distribution board. For indirect measurement, the sensor is connected via external current transformers with 50 mA secondary current.
Who is Huawei?
Huawei is a globally operating technology group and one of the leading manufacturers of inverters, energy management, and storage solutions for photovoltaics. The Smart Power Sensor series complements their portfolio with measurement technology for self-consumption and zero feed-in.
