SONOFF POWCT Ring Power Meter

【Split Core Current Transformer – Non-Invasive & Safe Monitoring】Measure current up to 100A with a split-core clamp design — no need to touch live wires. Just snap the CT sensor open or closed via side latches for quick and safe installation, ideal for both DIYers and professionals.
【Real-Time Energy Monitoring – Room or Circuit Level Insight】Install POWCT in your home’s electrical panel to monitor power usage by room, circuit, or heavy-duty appliances. Identify energy waste, optimize power consumption, and gain full control over your electricity usage.
【Track Exported Power to the Grid – Optimize Solar Efficiency】POWCT is more than just an energy monitor—it’s a smart solution for tracking bidirectional power flow, including energy exported back to the grid. When integrated with solar inverters or battery storage systems, it provides real-time data on surplus electricity generation, helping you maximize self-consumption, reduce waste, and improve your return on investment from solar power.
【6-Month Historical Power Data – Auto Save & Exportable】Review hour-level electricity data for up to 6 months, and you can export it as files for energy analysis or reporting.
【Dry Contact Relay – Contactors & Load Control Supported】Equipped with a 2A dry contact output, POWCT can be connected to an external contactor to switch large electrical loads on or off. Perfect for industrial applications or smart energy management systems.
