Three-phase energy meter for Solplanet inverters SDM630-MCT

Energy meter for photovoltaic systems – precise measurement and integration

The three-phase energy meter SDM630-MCT is a key component in photovoltaic systems using Solplanet inverters. The device is designed for indirect measurement, which means it requires the use of external current transformers (not included) – providing flexibility in selecting the measurement range. This allows for accurate monitoring of energy production and consumption in the installation, which is important both for optimizing system performance and for settlements with the energy supplier.

Characteristics and application

SDM630-MCT is designed to work with Solplanet inverters, ensuring compatibility and reliable operation. Its main task is to measure electrical energy in a three-phase network, and thanks to the bidirectional measurement, it allows you to record both energy drawn from the grid and energy fed back into it by the photovoltaic installation. This allows for full control over energy flow and effective resource management. The device is used in both commercial and domestic installations, where precise measurement is crucial for monitoring the performance of the PV system.

Functionality and benefits

• Indirect measurement: Requires the use of current transformers (CT), allowing the measurement range to be adapted to specific installation needs. The ability to choose CT24 transformers with different parameters (e.g. 100A/5A, 150A/5A, 200A/5A, 250A/5A, 300A/5A) provides flexibility and measurement accuracy.
• Modbus RTU RS485 communication: Enables integration of the meter with BMS (Building Management System) and remote monitoring, allowing for continuous tracking of installation operating parameters and quick response to any problems.
• High accuracy: Compliance with IEC62053-21 and EN50470-3:2022(MID) standards guarantees the reliability of measurements and compliance with legal requirements for settlements with the energy supplier.
• Wide voltage range: Support for 3x230/400V AC voltages makes the meter compatible with most power grids.
• LCD display: A readable LCD display shows key measurement parameters such as voltage, current, active and reactive power, and energy consumption.
• Durability and reliability: A wide operating temperature range (-40℃~+70℃) and high resistance to electromagnetic interference ensure stable meter operation in various environmental conditions.
• Transformer configuration: The ability to configure current transformer settings allows the meter to be adapted to the specifics of the installation (e.g. setting the transformation ratio).
• Bidirectional measurement: Records both energy consumption and energy fed back into the grid.

The SDM630-MCT meter is a solid solution for professionals involved in the installation of photovoltaic systems and for users looking for precise monitoring of energy consumption in their homes or businesses. Remember to purchase appropriate CT24 current transformers!
