The Chint DDSU666 single-phase smart energy meter is designed to act as an ultra-precise bidirectional measuring unit in residential solar installations. It is used to monitor the flow of electricity between the public grid and the home in real time, enabling the inverter to intelligently regulate battery charging and optimise the household's overall energy consumption.

  • Measurement and Monitoring: This smart meter offers direct measurement up to 80A, RS485 communication via Modbus-RTU protocol and a backlit LCD display for accurate monitoring of active power.
  • This product is an accessory compatible with Sofar Solar inverters in the ESI range (models ESI 3K-S1, ESI 3.6K-S1, ESI 4K-S1, ESI 4.6K-S1, ESI 5K-S1, ESI 6K-S1) and all Deye single-phase hybrid inverters, specifically including models SUN-3.6K-SG03/05LP1, SUN-5K-SG03/05LP1, SUN-6K-SG03/05LP1, SUN-7.6K-SG05LP1 and SUN-8K-SG01LP1.
  • It allows you to configure the zero export function for full compliance with the electricity grid, while offering granular monitoring to maximise the efficiency of your photovoltaic installation.

    Chint DDSU666 Single-Phase Smart Meter


    The Chint DDSU666 Single-Phase Smart Meter is a high-precision smart energy meter designed for dynamic management of photovoltaic installations. Thanks to its bidirectional measurement, it allows you to monitor production, consumption and network import and export flows in real time, in order to maximise your self-consumption rate.





    Wide compatibility: Deye & Sofar Solar

    The Chint DDSU666 meter is a benchmark accessory for monitoring and managing zero injection. It is natively compatible with:

    • Deye single-phase hybrid inverters: SUN-3.6K / 5K / 6K / 7.6K / 8K series (SG01 / SG03 / SG05LP1).
    • Sofar Solar ESI inverters: ESI 3K-S1 to 6K-S1 models, with full integration with the SolarMan Smart application.

    Technical note: Communication via Modbus-RTU on RS485 connection, enabling instantaneous regulation of battery charge and precise management of grid injection.

    FAQ - Chint DDSU666 Smart Meter

    1. What is the purpose of the Chint DDSU666 meter in a solar installation? +
    This single-phase smart meter measures bidirectional electrical flows. It allows your inverter to monitor grid import/export in order to optimise your self-consumption and improve the overall efficiency of your photovoltaic installation.
    2. Which inverters is this meter compatible with? +
    The Chint DDSU666 is certified compatible with Sofar Solar inverters (ESI range) as well as all Deye single-phase hybrid inverters (SUN-3.6K to SUN-8K) using the Modbus protocol.
    3. Can zero feed-in be configured with this module? +
    Absolutely. By communicating with the inverter via RS485, it allows you to limit solar production to avoid any injection into the grid (Zero Export), thus ensuring the compliance of your electrical system.
    4. How does this meter help manage battery charging? +
    Thanks to its ultra-precise flow measurement, the meter indicates to the hybrid inverter the surplus energy available to charge your storage batteries, thus avoiding wasting the energy produced.
    5. Is the data accessible remotely? +
    Yes, once connected to your compatible inverter, active power and consumption information is transmitted to the monitoring application (such as SolarMan Smart) for granular tracking of your energy.
