Precise three-phase measurement for intelligent feed-in and energy management
The Huawei DTSU666-H, 3-phase, is a high-precision energy meter for recording grid consumption, feed-in, and consumption in photovoltaic systems . It forms the technical basis for reliable feed-in management and for optimizing self-consumption – especially in three-phase households and commercial installations.
Continuous measurement of all three phases provides a transparent overview of load flows. This is essential for systems with HUAWEI SUN2000 inverters , feed-in limits according to grid regulations, or for systems with energy storage .
Technical specifications
- Three-phase energy meter for low-voltage networks
- Measurement of voltage, current, power and energy
- Communication via RS485 / Modbus RTU
- Designed for current transformer measurement (CT connection)
- High measurement accuracy for consumption and feed-in data
- Compact design for DIN rail mounting in the meter cabinet
Advantages & Applications
- Precise recording of grid consumption and feed-in
- Optimal basis for feed-in limitation and load management
