Product information

Description

The ORNO OR-WE-530 three-phase electric energy meter is designed for accurate measurement and monitoring of active energy in residential and commercial installations. Rated for up to 100 A per phase and complying with MID-grade accuracy, this 4-module device mounts on a DIN TH-35 mm rail and supports multi-tariff metering. An RS-485 communication port enables integration with building automation or energy management systems, while PV-Ready functionality allows connection in photovoltaic installations.

Advantages

The meter provides certified MID accuracy for reliable billing and monitoring. Its multi-tariff capability records energy consumption across different tariff periods, improving tracking of variable rates. Built for DIN-rail mounting with a compact 4-module form factor, it saves distribution board space. The RS-485 interface offers wired communication for remote reading and integration with third-party controllers or data loggers. The PV-Ready feature supports net metering and monitoring of solar generation alongside grid consumption.

Suitable for

  • Residential apartment blocks and single-family homes with three-phase supply
  • Small commercial premises and light-industrial installations
  • Energy monitoring and management systems requiring RS-485 connection
  • Photovoltaic systems where generation and consumption need to be tracked
  • Multi-tariff billing or time-of-use metering applications

Key specifications

  • System: three-phase active energy measurement
  • Rated current: up to 100 A per phase
  • Accuracy class: MID-certified accuracy class for billing
  • Form factor: 4-module width for DIN TH-35 mm rail mounting
  • Tariffs: multi-tariff metering capability
  • Communication: RS-485 serial port for Modbus/other protocol integration
  • Photovoltaic compatibility: PV-Ready for solar generation monitoring

How to use

Install the meter on a standard TH-35 mm DIN rail inside the electrical distribution board. Connect the three-phase incoming and outgoing conductors according to local wiring regulations and ensure proper neutral and protective earth connections. Configure tariff settings and time zones as required for multi-tariff operation, and set communication parameters on the RS-485 port to match the receiving system. Commission the meter by verifying phase sequence, continuity, and that readings match expected loads. For photovoltaic installations, follow PV system wiring guidelines to connect generation metering points.

Usage recommendations

Use the RS-485 interface with compatible energy management systems and set correct communication parameters (baud rate, parity, address) before integration. Ensure installation and commissioning are performed by a qualified electrician and comply with local electrical codes. Periodic verification against reference measurements is recommended to maintain billing accuracy.
