Solar and Grid Energy Monitoring with Clamp-On Smart Energy Meters
Short answer: Use a clamp-on smart energy meter with bidirectional measurement to see how much energy a building uses and how much its solar system produces. The OWON PC4713, PC473, PC321, PC341, PC311 and PC472 datasheets all list bidirectional measurement of energy usage and solar production.
What can you monitor?
- Real-time voltage, current, power factor, frequency and active power on every model; reactive and apparent power on the PC4713.
- Energy usage and solar production through bidirectional measurement.
- Historical data, displayed and exported in the app on the Tuya-compliant models.
- Individual circuits, with up to 16 sub CTs on the PC341.
Which meter fits which electrical system?
| Electrical system | OWON meters that list it |
|---|---|
| Single-phase | PC4713, PC473, PC321, PC341, PC311, PC472 |
| Split-phase | PC4713, PC321, PC341 |
| Three-phase four-wire | PC4713, PC473, PC321, PC341 |
| Three-phase three-wire / delta | PC4713-W-E-TY/3W (per its datasheet) |
How is the data accessed?
| Need | Choose |
|---|---|
| Monitor in a mobile app | Tuya-compliant models in the Smart Life app |
| Send data to your own server or read it locally | PC4713 Open Series (HTTP, MQTT, Modbus TCP, RS485 Modbus RTU) |
| Stable wired network connection | PC4713 models with Ethernet (-E-) |
| Per-circuit detail | PC341 with 50 A sub CTs |
Installation notes
- Choose CT sizes that fit the cables and currents. See the CT clamp size guide.
- Place CTs with the arrow pointing towards the loads, following the quick start guide.
- Have a qualified electrician install the meter.

Frequently asked questions
Do I need a gateway for these meters?
No. The OWON clamp-on meters in this solution connect over Wi-Fi, and the PC4713 models also offer Ethernet or RS485. They do not need a ZigBee gateway.
