1. Electric energy measurement

2. Data analysis and optimization

3. Fault diagnosis and maintenance

4. Grid-connected operation and scheduling
For grid-connected photovoltaic power generation systems, DC energy meters can achieve two-way communication and coordinated control with the power grid. It can upload the power generation data of solar panels to the grid dispatch center, allowing grid dispatchers to understand the operating status of the photovoltaic power generation system and dispatch the power generation of solar panels according to grid needs. This helps achieve coordinated operation of the photovoltaic power generation system and the power grid, and improves the stability and reliability of the power system.
