Solis 3phase Meter DTSD1352 with 3 150A 5A CTs

The Solis 3phase Meter DTSD1352 with 3x150A:5A CTs is a three-phase energy meter designed for accurate monitoring and export limitation in Solis solar PV systems, including three 150A:5A current transformers for precise electrical parameter measurement.

Product Description

The DTSD1352 is a high-precision three-phase meter that enables full 24-hour net power and consumption monitoring, supporting export power management and grid compliance in Solis inverter setups. It measures various electrical parameters, including temperature, and supports remote communication and control. Supplied with three 150A:5A CTs, it is ideal for single-inverter deployments but can be used in multi-inverter systems with appropriate configuration. For larger inverters like 110kW, higher-rated CTs (e.g., 200A:5A) are recommended.

Key Features

• Temperature measurement: Integrated sensor for environmental monitoring.
• Remote communication and control: Enables smart grid integration and remote management.
• Multi-parameter measurement: Tracks voltage, current, power, energy, and more.
• Export limitation: Supports zero-export or controlled export configurations.
• Split-core CTs: Easy installation without disconnecting cables.
• High accuracy: Ensures reliable data for system optimization.
• DIN rail mount: Compact and easy to install in electrical panels.
