The CHINT Tri + CTs Smart Meter is a three-phase electricity meter with three external current transformers, specially designed for three-phase photovoltaic installations equipped with a Solenso DTU-SLS or DTU-SLT router.
Why a three-phase meter with 3 CTs?
- Mandatory three-phase networks: 3P+N (400V) installations where single-phase is not possible
- High power ratings: Measures up to 100A, 300A or 600A per phase depending on the CT rating selected
- Phase balancing: Independent monitoring of L1/L2/L3 to detect imbalances
- Installation without interruption: Clamp-on CTs around the 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 features
- Phase-by-phase measurement (generation/consumption/export)
- Automatic detection of load imbalances
- 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
Commercial applications
Ideal for SMEs, light industry, multi-occupancy buildings, farms and large three-phase residential properties with Solenso micro-inverters.

CHINT Three-Phase Smart Meter with Current Transformers
The CHINT Tri + CTs Smart Meter is a three-phase bidirectional electricity meter designed for three-phase photovoltaic installations equipped with a Solenso SLS or SLT router. With its three external current transformers, it enables accurate phase-by-phase measurement of solar generation, 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:
- Three-phase installations are mandatory: 3P+N three-phase networks (400V between phases) where a single-phase meter cannot operate
- High power ratings: 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
- Live 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 (3 phases + neutral) model compatible with three current transformer sizes:
| 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: Current transformers must be supplied by Solenso to ensure compatibility and measurement accuracy with the DTU-SLS/SLT router.
Professional-grade accuracy for three-phase installations
The CHINT DTSU666 meter offers 1% class accuracy for 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 data from and monitor photovoltaic micro-inverter installations. Thanks to Modbus RTU communication via RS485, the system offers:
- Real-time three-phase measurement (generation/consumption/export per phase)
- Calculation of overall and per-phase self-consumption rates
- Detection of load imbalances between phases
- Zero export function to limit grid injection
- Detailed history data on the Solenso app
Professional installation on a DIN rail
The CHINT DTSU666 meter is mounted on a 35 mm DIN rail and occupies 4 modules in width (72 mm). The three current transformers are attached using simple clamps around the three phases (L1, L2, L3), without the need to switch off the electrical circuit.
Industrial Modbus RTU communication
The Modbus RTU protocol via RS485 interface is the industry standard for medium to high-power three-phase installations. This connectivity ensures:
- Reliable data transmission even over long distances (up to 1200 m)
- Fast and robust communication, resistant to electromagnetic interference
- Compatibility with professional monitoring systems
- Native integration with the Solenso DTU-SLS/SLT router
Key technical specifications
- Network type: Three-phase 3P4W (3 phases + neutral)
- Input voltage: 176–288 Vac per phase (wide range)
- Measured current: 0-100A / 0-300A / 0-600A depending on the selected CT
- 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)
Selecting the appropriate current transformer
Select the CT rating based on 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 cater for future expansion of the installation.
Recommended professional applications
