The smart meter PCB is an intelligent measurement core for new energy power consumption, designed to replace traditional meters with precise data collection and remote communication capabilities. It withstands indoor/outdoor environmental conditions, integrating energy measurement circuits, data storage modules, and wireless/wired communication interfaces. It accurately records electricity consumption (including new energy generation and grid power), supports two-way metering for distributed energy systems, and transmits data to the power grid management platform in real time. Enabling intelligent billing, load monitoring, and energy management, it is widely used in residential, commercial, and industrial scenarios, facilitating smart grid construction and new energy popularization.
