The Huawei Smart Meter DDSU666-H is a high-precision single-phase energy meter designed for real-time monitoring of photovoltaic installations. This smart sensor is a key component in maximising self-consumption, enabling accurate measurement of electrical flows between solar production, household consumption and injection into the public grid.
Seamlessly integrated into the Huawei FusionSolar ecosystem, this Smart Meter communicates via RS485 with the brand's inverters to provide dynamic energy management. In particular, it allows for "Zero Feed-in" configuration and optimises the charge/discharge cycle of LUNA2000 batteries. Thanks to its external current transformer (CT), it supports measurements up to 100A, ensuring safe and simplified installation without interrupting the main circuit.
The DDSU666-H is compatible with the following Huawei solutions:
Its compact DIN rail format and class 1 accuracy make it an essential accessory for intelligent and efficient control of your residential solar installation.

The Huawei DDSU666-H single-phase 100A Smart Meter is the intelligent energy meter specially designed for single-phase residential photovoltaic installations. With its class 1 measurement and native compatibility with Huawei SUN2000 hybrid inverters, this meter offers precise monitoring and automatic optimisation of your solar self-consumption.
Unlike the DTSU666-H three-phase model, the DDSU666-H has been specifically developed for single-phase installations, which account for the majority of homes in Belgium and Europe:
Capable of measuring up to 100 amps in single-phase, the DDSU666-H is perfectly suited to residential photovoltaic installations from 3 to 10 kWp, covering the vast majority of domestic needs.
The DDSU666-H Smart Meter is essential for fully exploiting the capabilities of Huawei single-phase hybrid inverters:
Maximised self-consumption: the meter measures your solar production and domestic consumption in real time. The inverter automatically adjusts energy flows to encourage local use of your green electricity.
Optimum battery management: Coupled with Huawei Luna 2000 batteries, the Smart Meter enables intelligent storage based on your consumption habits, weather forecasts and your supplier's day/night tariffs.
Compliant injection limits: For installations subject to network injection limits (e.g. 3 kW), the meter ensures precise dynamic regulation without loss of production.
True to Huawei's philosophy, the DDSU666-H combines technical performance with ease of use:
With a total power consumption of just 1 watt, the Smart Meter DDSU666-H is one of the most energy-efficient meters in its class:
Installation with single-phase hybrid inverter: The DDSU666-H is essential for all Huawei single-phase installations with Luna 2000 battery storage. It ensures perfect coordination between solar panels, batteries, domestic consumption and the electricity grid.
Real-time monitoring via FusionSolar: Connected to the Huawei ecosystem, the meter transmits all its data to the FusionSolar mobile application. You can monitor your production, consumption, self-consumption rates and savings from your smartphone, wherever you are.
Belgian and European regulatory compliance: The DDSU666-H complies with all the current standards for energy meters and can be installed in accordance with the requirements of Belgian distribution network operators.
If your domestic electrical installation is 230V single-phase (the standard configuration in most homes), the DDSU666-H is the optimal choice:
