Huawei Smart Power Sensor DTSU666-HW three-phase smart power meter

Huawei DTSU666-HW is a three-phase smart power sensor designed for measuring energy flow in compatible Huawei photovoltaic systems. The specified model supports communication via RS485 Modbus and Wi-Fi.

The DTSU666-HW model features high adaptability: it can be connected directly (depending on current limits) or using current transformers (CT), making it ideal for both residential and larger commercial electrical connections. The meter communicates directly with Huawei inverters via the RS485 (Modbus-RTU) communication interface. This enables dynamic power limitation solutions (Zero-Export) and ensures precise charging and discharging balance of LUNA2000 batteries according to the household's consumption needs.
