The Solis Single-Phase Meter with External 120A CT | ACR10R16DTE is a practical and reliable monitoring solution for compatible Solis single-phase inverter systems. Designed for DIN-rail installation, this meter is supplied with an external split-core 120A current transformer, making it especially suitable for retrofit projects and installations where quick wiring, safe construction, and accurate monitoring are important. The split-core design helps simplify installation because the conductor does not need to be disconnected during fitting.

This meter is designed for real-time power monitoring and energy management in photovoltaic and grid-connected applications. It measures key electrical values including single-phase current, voltage, active power, reactive power, apparent power, frequency, power factor, active energy and reactive energy, while the integrated LCD display and front buttons allow convenient local viewing and parameter setup. Standard communication is provided via RS485 with Modbus-RTU, allowing integration into compatible monitoring and control environments.
