Product information
The Eastron SDM630-M is a modern and multifunctional digital energy meter for three-phase networks, designed for comprehensive monitoring and analysis of electrical parameters. Thanks to its integrated Modbus RTU interface, it can be seamlessly integrated into building automation, energy management or photovoltaic monitoring systems. As a direct-reading meter capable of measuring up to 100 amps per phase, it offers precise data acquisition for a wide range of applications in commercial, industrial and demanding domestic settings.
Key features at a glance
- Precise measurement: Reliably measures a wide range of electrical parameters (kWh, kvarh, kW, kvar, kVA, P, F, PF, Hz, dmd, V, A, THD).
- Modbus RTU interface: This enables simple remote reading and integration into higher-level systems via RS485.
- Multifunctional: Suitable for energy monitoring, cost centre accounting, load management and PV system monitoring.
- Direct measurement up to 100A: No external current transformers are required for currents up to 100A per phase, which simplifies installation.
- Compact DIN rail format: Simple and space-saving installation in standard electrical distribution boards (4 TE).
Comprehensive energy monitoring for professional applications
The Eastron SDM630-M is the ideal instrument for detailed recording of energy consumption and generation. It enables precise monitoring of total consumption, individual machines or circuits, as well as the recording of energy generated by a photovoltaic system. Thanks to its ability to measure active and reactive energy in both directions (import/export), it is perfectly suited to monitoring PV systems with self-consumption. Its data forms the basis for energy efficiency measures, internal cost allocation or the monitoring of load profiles.
Precise measurement and flexible integration
In addition to active energy (kWh), this energy meter also measures reactive energy (kvarh), active power (kW), reactive power (kvar), apparent power (kVA), current (A), voltage (V), frequency (Hz), power factor (PF) and total harmonic distortion (THD) for voltage and current. The integrated Modbus RTU interface via RS485 enables all these values to be retrieved by systems such as data loggers, PLCs or energy management software. Direct measurement up to 100A eliminates the need for the complex installation and configuration of external current transformers in many standard applications.
Simple installation and operation
The SDM630-M can be installed quickly and easily on a standard top-hat rail (DIN rail) in electrical distribution boards. The large, backlit LCD display allows the most important measured values to be read directly on site. The buttons on the front panel allow you to navigate intuitively through the various display menus to view all recorded parameters or make basic settings.
Note
The SDM630-Modbus V2 is available in MID and non-MID versions. Following the expiry of the MID certificate, the new MID version is now designated as the SDM630-M.FAQs on the Eastron SDM630-M energy meter
What is the difference between the SDM630-M and other SDM630 variants?
The ‘M’ in the name stands for the integrated Modbus RTU interface. There are also variants with pulse outputs (e.g. SDM630-V1/-V2), with an M-Bus interface, or as MID-calibrated versions for billing purposes (SDM630-Modbus-MID).
Do I need external current transformers for this meter?
No, this model is designed for the Direct measurement Rated for currents up to 100 amperes per phase. No external current transformers (CTs) are required as long as this current range is not exceeded. Special transformer-based meters (e.g. SDM630MCT) are available for higher currents.
Is this meter suitable for official billing (e.g. with the energy supplier)?
No, this standard model is generally not It is MID-certified and must therefore not be used for billing based on kilowatt-hours. It is primarily intended for monitoring purposes and internal cost allocation. For billing purposes, you must use a variant with MID approval (e.g. SDM630-Modbus-MID).
How is the data read via Modbus?
To read out the data, you will need a Modbus master (e.g. a data logger, a PLC, a Raspberry Pi or a PC with the appropriate software and an RS485 interface). The master sends queries to the meter’s address on the RS485 network and reads the values from the defined Modbus registers. The register mapping can be found in the meter’s manual.

Although IP65-certified, installing it in a location protected from direct sunlight will extend the service life of the components.Protective devicesThe system features integrated DC isolators and a Type II DC surge protector to safeguard the installation against lightning damage and faults. FAQs on the Deye SUN-10K-SG01HP3Can I run this inverter on 48V batteries?No.This model is a high-voltage hybrid (HP3). For 48V low-voltage storage systems, you will need the LP3 series from Deye. Operating the system with the incorrect battery voltage may cause damage. It is essential to check the battery’s compatibility against the compatibility list beforehand.Do I need a separate smart meter for zero-feed-in?Generally speaking, no.Deye With these hybrid models, the appropriate 3-phase Smart is usually not supplied directly, so that the inverter can better measure household consumption at the grid connection point. However, the inverter can measure household consumption itself via the CT terminals and supply the required energy.Is the Wi-Fi module included in the scope of delivery?Yes.A Wi-Fi dongle for integration with the Solarman app or the Deye cloud portal is included as standard to enable you to monitor the system from anywhere in the world.Can the inverter control a heat pump?Yes.Via the programmable Smart-Load output, a signal can be sent to the heat pump (SG-Ready) to store thermal energy when there is sufficient solar yield or the battery is fully charged.
