SONOFF POWCT is a smart energy monitor with a 100A split core for safe and non-invasive installation. Monitor energy consumption in real time by room, circuit or device - ideal for home and industrial installations. Supports solar energy monitoring with bi-directional flow tracking. Includes 6 month history and dry contact relays for external switching of contactors to control large electrical loads.

【Split Core Current Transformer - Non-Invasive and Safe Monitoring】 Measure current up to 100A with the split core clamp - no need to touch live wires. Simply open or close the CT sensor using the side latches for quick and secure installation, ideal for DIYers and professionals alike.

【Real-Time Energy Monitoring - Room or Circuit Level Analysis】 Install POWCT in your home's electrical panel to monitor energy consumption by room, circuit, or high-power appliances. Identify energy waste, optimize energy consumption and gain complete control over your energy consumption.

【Track Power Exported to the Grid - Optimize Solar Energy Efficiency】 POWCT is more than just an energy monitor - it is an intelligent solution for tracking the bi-directional flow of energy, including power exported back to the grid. When integrated with solar inverters or energy storage systems, it provides real-time data on excess electricity production, helping you maximize your own consumption, reduce waste and improve your return on your solar investment.

【6 Month Energy History Data - Automatically Save and Export】 View up to 6 months of hourly energy consumption data and export it as files for energy analysis or reporting.

【Dry Contact Relay - Support Contactors and Load Control】 Equipped with 2A dry contact output, POWCT can connect to an external contactor to turn on and off large electrical loads. Ideal for industrial applications or intelligent energy management systems.
