Modelo: DTSU666-H- Sku: HUAWACC009
- Vendor: Huawei
Specifications
Product description
The Huawei DTSU666-H 250A Sensor is a high-precision three-phase energy meter, specially designed for solar installations with Huawei inverters. It enables reliable, real-time reading of key electrical parameters, including current, voltage, frequency, power, and energy, both consumed and generated. Thanks to its compatibility with RS485 and Modbus RTU protocol, it integrates easily with SmartLogger, EMMA, and other Huawei systems, offering advanced solutions such as feed-in limitation to the grid or dynamic energy management.
Main features
- 3P4W three-phase measurement with Class 1 accuracy, ideal for bidirectional energy control.
- External current transformers included (3 x 250 A / 50 mA) with 5 m cable.
- Modbus RTU communication via RS485, compatible with Huawei inverters and SmartLogger.
- Integrated LCD display for direct viewing of electrical parameters.
- 35 mm DIN rail mounting and compact size (100 × 72 × 65.5 mm).
- Powered by grid (phase voltage: 176–288 VAC; line: 304–499 VAC).
Advantages or benefits
- Allows zero or controlled feed-in configuration in solar installations.
- Facilitates energy management in homes, businesses, or industries with self-consumption.
- Helps to size batteries or loads based on actual consumption.
- Simple and quick installation, with pre-wired connectors and included accessories.
- Comprehensive and integrated monitoring on platforms such as FusionSolar or SPCS.
