Modelo: DTSU666- Sku: SUNGACC005
- Vendor: Sungrow
Specifications
Product description
The Sungrow DTSU666 Three-Phase Energy Meter is a bidirectional digital meter designed to work with Sungrow inverters and self-consumption systems. Thanks to its RS485 interface and Modbus RTU protocol, it enables integration of dynamic zero export control functions, real-time monitoring, and precise measurement of energy flow in three-phase installations. It is available in direct measurement versions up to 100 A and variants with current transformers for higher power systems.
Main features
- Three-phase 4-wire measurement with bidirectional active/reactive reading
- RS485 communication interface with Modbus RTU protocol
- Maximum current up to 100 A (direct version) or higher with CT
- Backlit LCD display for local reading
- DIN rail mounting in indoor electrical panels
Advantages or benefits
- Enables zero export control with Sungrow inverters
- Compatible with COM100A and COM100E communication boxes
- Accurate measurement of consumption and generation to optimize self-consumption
- Quick and easy installation with direct or CT versions
- Adapted for residential, commercial, and industrial installations
Purpose or applications
The DTSU666 is designed for three-phase solar installations with Sungrow inverters. It is used in self-consumption systems, industrial or commercial plants that require export control to the grid, and as a metering point in installations with centralized energy management.
