Sigenergy Sigen Power Sensor | Three Phase External CT 600A | DIN Rail | RS485 | Industrial Import/Export Monitoring
Three Phase 3 × 600A CT Included ±1% Accuracy Industrial Scale Part No: SIG-SENSOR-TP-CT600-DH
The Sigenergy Power Sensor TP-CT600-DH is the highest-capacity variant in the Sigen Power Sensor range — a three-phase energy metering device for large commercial and industrial installations where the incoming three-phase supply is rated above 300A per phase. Three external split-core current transformers rated to 600A per phase, with a 36mm inner bore diameter to accommodate large-section busbars and cables, are included in the box. The sensor connects via RS485 Modbus RTU to Sigenergy inverters, energy controllers and the SigenStor EMS, delivering real-time, high-accuracy monitoring of grid import and export across all three phases — enabling the full suite of Sigenergy intelligent energy management functions at industrial scale.
What the Power Sensor Enables
Positioned at the main grid connection point, the Power Sensor delivers live three-phase import/export data to the Energy Controller every 100ms — enabling precise, real-time energy management across the full site load at commercial and industrial scale:
- Dynamic load management — real-time inverter/battery throttling to prevent incomer overload
- Maximum demand management — limits grid import below a contracted demand threshold
- Export limitation — enforces a maximum export cap per DNO / G99 connection agreement
- Self-consumption optimisation — multi-inverter battery dispatch reduces import across all three phases
- AI tariff scheduling — live consumption data feeds the mySigen AI energy optimiser
- Accurate mySigen app energy flow display — site import/export, solar generation, battery and load
- Anti-backflow control when used with the Sigen Energy Gateway
💡 Industrial-scale metering: The 600A CT rating and 36mm bore diameter accommodate the large busbars and cable cross-sections typical of industrial switchgear, MCC enclosures and commercial distribution systems with high-current incomers. This is the correct variant for sites with three-phase supplies rated above 300A per phase and up to 600A per phase.

FAQs
How do I confirm which CT rating I need?
Check the rated current of the DNO main fuse or incomer protection device on each phase at the grid connection point. If the per-phase rating is between 301A and 600A, this 600A variant is the correct choice. If it is 300A or below, the SIG-SENSOR-TP-CT300-DH provides adequate headroom with a smaller CT and may be easier to handle. Always select the CT rating that exceeds — not merely equals — your maximum expected per-phase current to preserve measurement accuracy at full load.
Will the 36mm bore CT fit around my cables or busbars?
The 36mm inner bore diameter accommodates cable conductors or busbar sections up to approximately 36mm in their narrowest dimension. For very large flat busbars or conductors in tight groupings, verify the physical dimensions on site before ordering. If the bore is insufficient, consult Sigenergy or your distributor — higher CT bore accessories may be available for large industrial installations.
Is a G99 application needed when connecting Sigenergy storage to an industrial supply?
For commercial and industrial installations connecting generating plant (including battery storage in export mode) to the Distribution Network, a G99 application to the DNO is typically required where total export capacity exceeds 16A per phase. The Power Sensor's export limitation capability allows the system to enforce a zero-export or maximum-export limit as a condition of the DNO connection agreement, but the G99 process itself must be managed by the responsible engineer or DNO connection team. This description is for general guidance only — always confirm compliance requirements with your DNO and a qualified electrical engineer.
