【Typical Applications】
For application scenarios with a small number of terminal devices and scattered installations, the PMC-4230 provides a cost-effective choice for power monitoring and data migration to the cloud, integrating communication gateway, three-phase electricity meter, and logic control functions, and is often used in scenarios such as power operation and maintenance, environmental protection electricity and water supervision, integrated optical and storage intelligent microgrids, and integrated energy services.
In the distributed photovoltaic power station, the installed capacity of residential photovoltaic is about 8kWp, and the grid-connected voltage is 220v, which can be divided into the grid-connected mode of "self-generation and self-use, and the surplus power is not connected to the grid" according to the requirements of different regions.
PMC-4230 gateway type fusion controller, which integrates gateway, electricity meter, and edge control, provides communication + anti-backflow solutions for household photovoltaics.
