Precise three-phase measurement for intelligent PV energy management
The HUAWEI DTSU666-FE, 3-phase, is a precise energy meter for recording grid consumption, feed-in, and consumption in photovoltaic systems . It forms the technical basis for clean energy management and enables optimal control of inverters , energy storage systems , and dynamic power limits – especially in three-phase households and commercial buildings.
Continuous measurement of all three phases provides a transparent overview of load flows and allows for targeted optimization of self-consumption . This is particularly relevant for systems with feed-in limitations, integrated storage, or intelligent load management.
