Key Benefits
Single, Split & 3-Phase Compatible
One clamp meter covers single-phase, split-phase and three-phase 4-wire systems — three CT clamps monitor the whole installation.
Bidirectional Measurement
Measures both energy consumed and produced — ideal for solar PV self-consumption and net-metering setups.
WiFi + Tuya Ecosystem
2.4GHz WiFi with BLE-assisted pairing; monitor and control in real time via Tuya Smart / Smart Life apps.
External Magnetic Antenna
Keeps the signal reliable even inside metal distribution boxes — no shielding interference.
Ideal For
Common deployment scenarios where PC321-W-TY Single/Three-Phase WiFi Smart Energy Clamp delivers the most value.
Solar PV Self-Consumption
Bi-directional metering tracks solar generation, grid import/export and household consumption in real time.
Whole-Home Energy Monitoring
Three CT clamps monitor total household consumption across single, split or three-phase supplies via the Tuya app.
Split-Phase & 3-Phase 4-Wire Installations
Covers North American split-phase and standard three-phase four-wire systems (3-wire & Delta not supported).
Residential & Commercial Submetering
Non-invasive CT clamp installation from 80A to 750A, wall or DIN-rail mounting — no rewiring required.
HVAC & EV Charging Circuits
CT range and 15-second reporting cycle suit HVAC systems and EV charger energy management.
Solar Installer Commissioning
Verify PV system performance and validate inverter output during installation using real-time clamp data.
