Huawei SmartPS-250A-T0 (DTSU666-H): Advanced Energy Management
The SmartPS-250A-T0 is a three-phase indirect measurement wattmeter that allows for precise monitoring of energy flow. It is an essential component for configuring zero-export systems, managing the charging of LUNA2000 batteries, and optimizing self-consumption in real time.
Main Technical Features
- High Accuracy: Certified with Class 1 in active energy measurement (error <1%) and ±0.5% in voltage/current.
- Measurement Capacity: Supports up to 250A using the 3 included current transformers (CTs).
- Energy Efficiency: Extremely low internal consumption, less than 1.5 W.
- Interface Intuitive: Integrated LCD screen that facilitates local configuration and reading of electrical parameters.
- Robust Communication: Uses Modbus-RTU protocol via RS485 for seamless integration with the Huawei ecosystem.
- Compact Design: Easy installation on a DIN35 rail.

This sensor is designed to work with the full range of Huawei three-phase inverters, enabling intelligent energy management (ESS) and EV chargers:
- Series SUN2000 M1: 3KTL to 10KTL-M1 models (Residential Hybrids).
- SUN2000 M2 / M3 Series: Medium-power commercial inverters.
- SUN2000 MB0 Series: New 12K to 25K-MB0 hybrid models.
- SUN2000 MAP0 Series: Latest generation inverters compatible with the SmartGuard system.
- SUN2000 M0 Series: Previous generation three-phase inverters.
Installation Benefits of the Huawei SmartPS-250A-T0 (DTSU666-H) Meter
Measurement Indirect: Thanks to its open-core current clamps (CT), it is not necessary to cut the main wiring of the installation for mounting. Plug & Play: Automatically detected by the FusionSolar app during commissioning.
Network Versatility: Compatible with 3-wire (3P3W) and 4-wire (3P4W) three-phase systems.
Technical Note: The SmartPS-250A-T0 is positioned as the successor to the standard DTSU666-H, offering wider baud rates and a higher data refresh rate for more dynamic management.
