Product Name: Smart WiFi Energy Meter, Bidirectional, Three-Phase 3P+N

Model: DTS6619-3PN

Purpose: Measurement and protection in three-phase electrical installations, with a special function for photovoltaic panels (bidirectional: measures both consumed energy and energy fed back to the grid)

Features and Properties:

• Real monitoring of energy production and consumption
• WiFi connectivity, control and monitoring via Tuya or Smart Life apps
• Integrated and adjustable protection including:
• Overvoltage (adjustable threshold between 120 V and 300 V)
• Undervoltage (adjustable threshold between 80 V and 210 V)
• Overcurrent (adjustable between 1 A and 100 A)
• Earth leakage current sensitivity (10 mA to 99 mA)
• Temperature protection (adjustable between 10 °C and 85 °C)
• Bidirectional measurement, useful for photovoltaic installations, displays both consumed and produced energy
• App display, including total amount of consumed energy
• Mechanical protection: IP20

Technical Specifications:

• Supply Voltage: AC 80-300 V, 50/60 Hz (full range)
• Maximum continuous current: 100 A (adjustable from 1-100 A)
• Bidirectional metering: Energy measurement in both directions
• Connectivity: WiFi (2.4 GHz), Tuya / Smart Life apps
• Leakage protection: 10 - 99 mA (adjustable)
• Temperature protection: 10 °C - 85 °C (adjustable)
• Energy display: Consumption (kWh) and production (kWh)
• General protection: Overvoltage, undervoltage, overcurrent

Application Areas:

• Monitoring and control of three-phase photovoltaic installations
• Energy measurement in both directions: consumption and feed-in to the grid
• Electrical protection for homes, offices, installations with solar panels
• Integration with Smart Home systems for detailed energy monitoring

Operation and Indications:

• The meter displays consumption and electrical production in the mobile app
• Automatically cuts off power if defined limit values are exceeded (current, voltage, temperature, leakage)
• The app allows immediate and historical viewing of electrical and energy parameters

Useful Notes:

• For installation, disconnect the network before mounting
• Mount on DIN rail (if the model allows), with covers suitable for up to 100 A
• After installation, adjust protection limit values according to specific needs
• Regularly check connections and ensure good WiFi reception for the device
• Bidirectional operation is essential for proper monitoring of photovoltaic production
