Three-Phase Energy Meter Solax Chint DTSU666-D

Product description

The Solax Chint DTSU666-D Three-Phase Energy Meter is a professional device designed to measure with high accuracy the consumption and generation of energy in three-phase solar installations. With direct connection up to 100 A and RS-485 Modbus RTU communication, this meter is optimized for integration with Solax inverters, enabling advanced functions such as zero injection, remote monitoring, and complete energy control.

Main features

• Direct connection up to 80–100 A without the need for external transformers
• RS-485 communication with Modbus RTU and DL/T645-2007 protocols
• Backlit LCD display with clear parameter visualization
• Bidirectional measurement of active energy, reactive energy, and power factor
• Quick installation on 35 mm DIN rail and compact design
• Class B/1.0 accuracy according to EN50470-1/3 standard

Advantages or benefits

• Allows the Solax inverter to automatically control grid injection
• Prevents penalties or energy losses in systems with limited feed-in
• Enables real-time monitoring through Solax platforms
• Compatible with multiple electricity tariffs: peak, flat, off-peak, etc.
