Featuring a compact, modular design, the meter fits standard DIN rails and integrates seamlessly with Tuya's smart home ecosystem, allowing remote monitoring, automated load management, and compatibility with renewable energy systems. The four-pole configuration ensures balanced protection and measurement across all three phases and the neutral wire, making it ideal for complex industrial and commercial setups.
Bidirectional Energy Flow: Accurately measures energy import (from grid to load), export (from renewable sources to grid), and storage (to/from batteries), essential for net metering, virtual power plants, and demand response programs.
Tuya IoT Ecosystem Integration: Connects directly to Tuya Smart app via Wi-Fi (2.4GHz) or Ethernet, enabling real-time data visualization, historical trend analysis, and automation rules. Works with Alexa, Google Assistant, and Tuya-compatible smart switches for unified energy management.
High Precision & Reliability: Meets IEC 62053-22 standards with 0.5S class accuracy for active energy and 2S class for reactive energy. Features anti-tamper technology, including sealed terminals and firmware encryption, to prevent unauthorized interference.
Scalable Current Measurement: Supports direct connection for up to 100A or CT-based measurement for higher loads, with automatic CT ratio configuration via the app. Ideal for small shops, large factories, and utility-scale energy projects.
Industrial Energy Management: Deployed in factories and warehouses to monitor energy usage across multiple departments, identify inefficiencies, and optimize load scheduling to avoid peak demand charges. The bidirectional metering supports onsite generation from CHP systems or wind turbines.
Commercial Buildings with Storage: Used in office complexes and data centers with battery energy storage systems (BESS), balancing energy between the grid, storage, and loads to minimize costs during peak hours.
Residential Multi-phase Setups: Suitable for large homes or multi-unit buildings with three-phase power, enabling detailed monitoring of energy consumption per apartment and integration with rooftop solar for community-scale net metering.
Utility Substations: Provides accurate bidirectional data for power companies to manage grid stability, validate feed-in tariffs, and implement dynamic pricing models for commercial customers.
Q: What is the purpose of the ground fault (GF) protection?
A: GF detection identifies 漏电 currents as low as 30mA, tripping the circuit to prevent electric shock hazards and equipment damage, compliant with international safety standards (IEC 61008).
Q: Can this meter be used in a single-phase system?
A: While designed for three-phase 4P systems, it can technically monitor single-phase by using one phase, but this is not recommended. Tuya offers single-phase bidirectional meters (RMZT SF 1P 63A) for better compatibility.
Q: How often does the meter sync data with the Tuya cloud?
A: Real-time data updates every 15 seconds, with hourly/daily/monthly summaries stored locally for 365 days and in the cloud indefinitely (subject to Tuya's data retention policies).
Q: Is a gateway required for Ethernet connectivity?
A: No, the meter has a built-in Ethernet port for direct connection to local networks, ideal for industrial setups requiring wired connectivity. Wi-Fi is recommended for residential and small commercial use.
Q: Can I use this meter with non-Tuya smart devices?
A: Yes, it supports standard communication protocols (Modbus RTU, DLMS/COSEM), enabling integration with third-party energy management systems alongside Tuya's ecosystem.
