The Smart Meter CHINT Tri + CTs is a three-phase electricity meter with three external current transformers specially designed for three-phase photovoltaic installations fitted with a Solenso DTU-SLS or DTU-SLT router.



Why a three-phase meter with 3 CTs?

  • Compulsory three-phase networks: 3P+N (400V) installations where single-phase is not possible
  • High power: Measures up to 100A, 300A or 600A per phase, depending on the CT rating chosen
  • Phase balancing: Independent L1/L2/L3 monitoring to detect imbalances
  • Uninterruptible installation: CTs clamped around phases, no circuit interruption



DTSU666 high-capacity three-phase model

The CHINT DTSU666 (3P4W) meter offers 1% accuracy with Modbus RTU RS485 communication. Compatible with 3 CT ratings: 100A (10-30kWp), 300A (30-90kWp) or 600A (90-180kWp).



Professional three-phase functionality

  • Phase-by-phase measurement (production/consumption/export)
  • Automatic load imbalance detection
  • Long-distance RS485 communication (up to 1200m)
  • 35mm DIN rail mounting (4 modules)
  • Ultra-low power consumption: 1.5W
  • Operating temperature : -25°C to +55°C



Professional applications

Ideal for SMEs, light industry, collective buildings, farms and large three-phase homes with Solenso microinverters.

Smart Meter CHINT Three-Phase with Current Transformers



The Smart Meter CHINT Tri + CTs is a three-phase bi-directional electricity meter designed for three-phase photovoltaic installations equipped with a Solenso SLS or SLT router. With its three external current transformers, it provides accurate phase-by-phase measurement of solar production, load consumption and energy exported to the grid.






Why choose a three-phase meter with current transformers?

The three-phase model with CTs is essential for three main reasons:



  • Mandatory three-phase installations: 3P+N three-phase networks (400V between phases) where a single-phase meter cannot operate.
  • High power: Photovoltaic systems from 10 kWp to 30+ kWp requiring measurements of up to 100A, 300A or 600A per phase
  • Phase balancing: Independent monitoring of each phase to detect imbalances and optimise load distribution
  • Uninterruptible installation: clamp-on CTs allow installation without interrupting the power supply



Model DTSU666: The versatile three-phase meter

This kit uses the CHINT DTSU666 meter, a three-phase 3P4W model (3 phases + neutral) compatible with three current transformer ratings :



Modèle CT Courant max Application recommandée
CT-100A/5A 100A par phase Installations 10-30 kWc (PME, grandes habitations)
CT-300A/5A 300A par phase Installations 30-90 kWc (industrie légère, bâtiments collectifs)
CT-600A/5A 600A par phase Installations 90-180 kWc (industrie, grandes toitures commerciales)



Important: The current transformers must be supplied by Solenso to guarantee compatibility and measurement accuracy with the DTU-SLS/SLT router.






Professional accuracy for three-phase installations

The CHINT DTSU666 meter offers 1% accuracy on current, power and energy measurements, in line with professional standards for medium to high-power installations.



Paramètre mesuré Classe de précision
Tension de phase 0,5%
Courant / Puissance active 1%
Énergie active 1%



This accuracy enables reliable monitoring of all three phases independently, which is essential for optimising self-consumption and detecting anomalies (phase imbalance, localised over-consumption).






Compatibility with the Solenso three-phase ecosystem

This meter is designed to work in perfect synergy with the Solenso DTU-SLS and DTU-SLT routers, which collect and supervise photovoltaic microinverter installations. Thanks to Modbus RTU communication via RS485, the system offers :



  • Real-time three-phase measurement (production/consumption/export per phase)
  • Calculation of self-consumption rate overall and per phase
  • Detection of load imbalances between phases
  • Zero export function to limit grid injection
  • Detailed history on the Solenso application






Professional DIN rail installation

The CHINT DTSU666 meter is mounted on a 35 mm DIN rail and occupies 4 modules (72 mm). The three current transformers are simply clamped around the three phases (L1, L2, L3), with no need to break the electrical circuit.






Industrial Modbus RTU communication

The Modbus RTU protocol via RS485 interface is the industrial standard for medium to high-power three-phase installations. This connectivity guarantees :



  • Reliable data transmission even over long distances (up to 1200m)
  • Fast communication, robust to electromagnetic interference
  • Compatibility with professional supervision systems
  • Native integration with the Solenso DTU-SLS/SLT router






Main technical specifications

  • Network type: 3-phase 3P4W (3 phases + neutral)
  • Input voltage: 176-288 Vac per phase (extended range)
  • Measured current: 0-100A / 0-300A / 0-600A depending on CT selected
  • Communication interface: RS485 / Modbus RTU
  • Meter power consumption: ≤ 1.5 W
  • Operating temperature: -25°C to +55°C
  • Dimensions: 72 x 100 x 65.5 mm (4 DIN modules)




Choosing the right current transformer

Select the CT rating according to the installed power:



Puissance PV installée Courant max par phase CT recommandé
10-30 kWc ~15-45A CT-100A/5A
30-90 kWc ~45-130A CT-300A/5A
90-180 kWc ~130-260A CT-600A/5A



Tip: Allow a safety margin of 20-30% to anticipate future extensions to the installation.






Recommended professional applications

The Smart Meter CHINT Tri + CTs is ideal for :

  • SMEs and small industries with three-phase installations of 10-100 kWp
  • Collective buildings (blocks of flats, condominiums) with solar roofs
  • Farms with photovoltaic sheds
  • Commercial sites (supermarkets, shopping centres, car parks)
  • Large three-phase homes with high electricity consumption






Advanced monitoring via Solenso application

Combined with the DTU-SLS router, the meter enables comprehensive monitoring via the Solenso mobile application:

  • Total solar production and production per phase
  • Instantaneous and historical consumption
  • Self-consumption rate and savings made
  • Alerts in the event of imbalance or anomaly
  • Grid export/import with graphical display
