3-Phase Energy Meter – RS485 Modbus, External Split-Core CTs
High-accuracy three-phase energy meter with external split-core CTs, designed for solar PV systems, load monitoring, and Modbus-based energy management.
This three-phase DIN rail energy meter is designed for accurate monitoring of electrical systems in commercial, industrial, and solar PV applications. Using external split-core current transformers, it allows non-intrusive installation without disconnecting existing wiring, making it ideal for retrofit and live environments.
The meter provides full electrical parameter monitoring including voltage, current, active power, reactive power, apparent power, power factor, frequency, and cumulative energy consumption. It also supports bidirectional energy measurement, enabling tracking of both imported and exported energy, making it particularly well suited for solar PV systems and energy storage applications.
With high accuracy and fast response, the unit is capable of supporting dynamic energy environments such as grid-connected solar systems, micro-inverter installations, and AC-coupled battery systems. It can be used for load monitoring, energy optimisation, and system performance analysis.
Communication via RS485 Modbus-RTU enables seamless integration into SCADA systems, building management systems (BMS), or cloud platforms such as ProSight. The LCD display provides clear real-time data visibility, while the compact DIN rail design allows easy installation in switchboards and control panels.
