Huawei Smart Meters

There are two main types: single-phase meters (such as the DDSU666-H) and three-phase meters (such as the DTSU666-H and DTSU666-HW). Additionally, there is the Smart Power Sensor FE option, which connects to the inverter via internet/LAN. Each model supports different loads and wiring configurations, so the correct choice depends on your supply type and the current transformers required for your installation. If there is no Huawei inverter but you want to install a Huawei EV Charger, installing the Smart Power Sensor FE alone is enough to achieve dynamic charging.

Yes, if you want your SUN2000 inverter to manage power distribution intelligently. Without a meter, the inverter cannot monitor grid import or export. Adding one enables zero-export control, dynamic feed-in limitation, and accurate battery scheduling based on live consumption data.

The sensor displays your energy consumption to the inverter continuously. Using that data, the system adjusts output in real time, directing surplus solar power to charge batteries or shifting loads rather than exporting cheaply to the grid. The result is a higher proportion of self-generated energy consumed on site.

Yes. Single-phase properties use the DDSU666-H, while three-phase installations require a DTSU666-H or DTSU666-HW variant. The FE 100A model also supports both supply types within a single intelligent unit, giving installers flexibility across different residential and commercial projects.

The result is a higher proportion of self-generated energy consumed on site.

Most models in this series use external current transformers (CTs) rather than direct wiring. The DTSU666-H is available in two versions, 100A and 250A, with the 100A version having smaller clamps compared to the 250A version. The DTSU666-HW supports both direct connections and external CTs (with 1A or 5A secondary), offering even greater installation flexibility. Alternatively, the Smart Power Sensor FE connects via Ethernet cabling.

The meter acts as the central reference point for the entire system. It accurately measures what the property is consuming, what the solar panels are generating, and what the battery holds, then signals the inverter to charge, discharge, or export accordingly. This intelligent coordination maximises battery use and reduces grid dependence significantly.

The key factors are your supply type, single-phase or three-phase, and the current your installation draws. A qualified installer will assess your incoming supply, select the appropriate meter model and CT rating, and confirm compatibility with your inverter kit.
