The Huawei DTSU666-HW three-phase 80A Smart Meter is the next-generation smart energy meter with built-in WiFi connectivity. Designed for small and medium-sized three-phase photovoltaic installations, it combines Class 1 metering, wireless communication and native compatibility with Huawei SUN2000 inverters for optimum energy management and simplified configuration.
The DTSU666-HW model (suffix "W" for WiFi) stands out from the standard DTSU666-H range thanks to its integrated WiFi connectivity, offering a host of benefits:
Ultra-simplified installation: No more RS485 cables to run between the meter and the inverter. WiFi communication eliminates the need for data cabling, reducing installation time and the risk of wiring errors.
Flexible placement: Position the meter in the optimum place in your electrical panel without distance constraints from the inverter. WiFi provides sufficient range for most residential and commercial configurations.
Remote configuration: Set up and update the meter directly via the Huawei FusionSolar application, without having to physically handle the meter after the initial installation.
With its capacity of 80 amps per phase in three-phase, the DTSU666-HW is perfectly sized for:
Recommended sizing: The 80A model is suitable for three-phase photovoltaic installations from 5 to 24 kWp, i.e. around 15 to 60 solar panels depending on their unit output.
The DTSU666-HW WiFi Smart Meter fits seamlessly into Huawei's intelligent ecosystem:
Thanks to its WiFi connectivity, the DTSU666-HW offers an enhanced user experience:
Despite its advanced features, the DTSU666-HW is still easy to use:
With a power consumption of just 1.5 watts (slightly higher than the non-WiFi model due to the wireless communication module), the DTSU666-HW is extremely economical:
New installations: The WiFi model is particularly suited to new buildings and installations where you want to minimise wiring and facilitate future maintenance.
Retrofit and renovation: Ideal for adding monitoring to an existing installation without additional cabling work.
Decentralised installations: Perfect when the switchboard and inverter are far apart.
