📊 Meters & Monitoring: Smart Energy Management for Solar Systems
Take full control of your energy production and consumption with our professional range of Smart Meters and Monitoring Equipment. In a modern photovoltaic setup, visibility is power. A smart meter is the essential link that allows your inverter to "talk" to the grid, enabling precise export limits and maximizing your battery storage efficiency. At Termix.ro, we provide high-precision Single-Phase and Three-Phase Smart Power Sensors from industry leaders like Huawei and V-Tac, designed for real-time data accuracy and seamless system integration. ☀️📱📈
✨ Engineered for Prosumer Precision: The Termix Selection
Our 2026 catalog features advanced metering solutions that turn a standard solar array into an intelligent energy network:
-
Huawei Smart Power Sensors (DTSU666-H): The gold standard for Huawei FusionSolar systems. These three-phase meters (available in 100A and 250A versions) offer Class 1 measurement accuracy. They provide real-time data on voltage, current, and power factor via RS485 communication, essential for managing "Zero Export" or battery charging logic. 💎⚡
-
V-Tac Smart Meters (DDSU666): Reliable bi-directional metering for residential setups. Whether you are using a single-phase or three-phase V-Tac hybrid inverter, these meters ensure that your system perfectly balances solar generation with home loads, reducing your reliance on the grid. 🏠🔄
-
Bi-Directional Net Metering: Essential for prosumers. Our meters track both the energy you pull from the grid and the excess you feed back, providing the high-fidelity data required for accurate billing and energy credits. 📉💰
-
DIN-Rail Modular Design: Efficiency in installation. All our monitoring units are designed for standard 35mm DIN-rail mounting, allowing them to fit neatly into your existing electrical panel with a compact footprint.

📊 Component Guide: Single-Phase vs. Three-Phase Monitoring
| Meter Model | Grid Type | Max Current | Communication | Best For |
| Huawei DDSU666-H | Single-Phase | 100 A | RS485 / Modbus | Residential 3kW–5kW |
| Huawei DTSU666-H | Three-Phase | 100 A / 250 A | RS485 / Modbus | Standard Family Homes |
| V-Tac DDSU666 | Single-Phase | 80 A | RS485 / Modbus | DIY / Small Offices |
| V-Tac VT-545 | Three-Phase | Variable | RS485 | Large Estates / C&I |
🛠️ Strategic Features for Intelligent Automation
-
Real-Time App Integration: Knowledge at your fingertips. By connecting these meters to your Huawei FusionSolar or V-Tac Smart app, you can view live "Energy Flow" diagrams, showing exactly how much power is coming from the sun, the battery, or the grid at any second. 📱✨
-
Export Limitation (Zero-Export): Protect your grid connection. For systems where the utility provider limits injection, these smart meters allow the inverter to throttle production in milliseconds to match only the local load, preventing unwanted export. 🛡️🛑
-
Energy Consumption Analytics: Identify "vampire loads" in your home. By monitoring your consumption patterns over 24 hours, these sensors help you decide when to run high-power appliances (like heat pumps or EV chargers) to make the most of your free solar energy. 🧺⚡
-
High Measurement Accuracy: With Class 1 (active energy) and Class 2 (reactive energy) ratings, our Huawei and V-Tac meters ensure that the data driving your battery charging and grid interaction is precise and reliable. 🎯📊
