About This Product

The SE-MTR-3Y-400V-A is a SolarEdge energy meter with Modbus communication for measuring site production, consumption and grid import or export. It is designed for use with compatible SolarEdge inverters and gateways and can provide the real-time power measurements needed for monitoring, export limitation and energy-management functions. The meter supports both single-phase and three-phase 230/400 V installations and mounts inside a standard electrical switchboard.

Who This Product Suits

The SE-MTR-3Y-400V-A suits SolarEdge residential and commercial installations where accurate measurement of electricity flow is required. It can be used for consumption monitoring, production metering and import/export measurement, including systems where export limitation is configured. It is particularly useful when a SolarEdge inverter needs reliable site power data for monitoring or energy-management functions.

Specifications Explained

The SE-MTR-3Y-400V-A supports both single-phase and three-phase electrical systems and is designed around nominal 230/400 V supplies. Communication with compatible SolarEdge equipment is through a three-wire RS485 Modbus connection, with a response time of up to 200 milliseconds and built-in 120 ohm RS485 termination.

The meter uses external 333 mV current transformers to measure current flow, allowing different CT sizes to be selected to suit the installation. SolarEdge specifies measurement accuracy of up to ±1.25% across the rated CT operating range, making the meter suitable for production, consumption and import/export monitoring. Current transformers are selected separately according to the electrical service and are required for operation.

The unit consumes up to 3 W and is compact enough for installation inside a standard switchboard. LED indicators on the front assist installers with checking operating and communication status during commissioning.

Summary

The SE-MTR-3Y-400V-A provides accurate energy measurement for compatible SolarEdge systems using RS485 Modbus communication. It supports single-phase and three-phase installations and can be used for production monitoring, consumption monitoring, import/export measurement and export limitation. Its compact DIN-rail design and wide range of compatible current transformers make it suitable for both residential and commercial SolarEdge installations.
