Based on the measured data, the inverter and monitoring system can show in real time how much energy the building uses, how much is produced, and how much is fed into the grid. This enables accurate billing, energy management, and intelligent control.\u003c\/p\u003e\n\n \u003cp\u003eThe device is easily installed on a DIN rail and its LCD display allows you to quickly check basic data. Its communication is via RS485 (Modbus-RTU) standard, so it connects reliably to Huawei inverters and systems.\u003c\/p\u003e\n\n\u003cp\u003e \u003cstrong\u003eWhich one should you choose?\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n\n\u003cli\u003e\n\n \u003cstrong\u003eDDSU666-H – 100A, 1 phase:\u003c\/strong\u003e if the building operates with a single-phase network and the main fuse rating is below 100 A.\u003c\/li\u003e\n\n\u003cli\u003e\n\n \u003cstrong\u003eDTSU666-H – 100A, 3 phases:\u003c\/strong\u003e for three-phase networks when the maximum current per phase remains below 100 A.\u003c\/li\u003e\n\n\u003cli\u003e\n\n \u003cstrong\u003eDTSU666-H – 250A, 3 phase:\u003c\/strong\u003e for higher consumption, three-phase systems where the current per phase can exceed 100 At.\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\n\u003cp\u003e \u003cstrong\u003eMain features:\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n\n\u003cli\u003e Real-time measurement of consumption and production\u003c\/li\u003e\n\n\u003cli\u003e High accuracy measurement class (Class 1)\u003c\/li\u003e\n\n\u003cli\u003e LCD display for quick reading of data\u003c\/li\u003e\n\n\u003cli\u003e RS485 communication with Huawei inverters\u003c\/li\u003e\n\n\u003cli\u003e Low power consumption (≤1.5W)\u003c\/li\u003e\n\n \u003cli\u003eDIN rail mountable, easy installation\u003c\/li\u003e\n\n\n\u003c\/ul\u003e","brand":"Huawei","offers":[{"title":"Default Title","offer_id":51776582156631,"sku":"HUA-DDSU666-H-100A","price":39043.0,"currency_code":"HUF","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0932\/6415\/0871\/files\/huawei-smart-power-sensor-ddsu666-h-100a-1f-ddsu666-h-100a-1f_1.webp?v=1758804938","url":"https:\/\/nexvosolar.hu\/en\/products\/huawei-smart-power-sensor-ddsu666-h-100a-1-fazis","provider":"Nexvo Solar","version":"1.0","type":"link"}
