Distributed solar photovoltaic inverter monitoring

One 、 Photovoltaic power generation site
Nowadays, countries all over the world attach great importance to photovoltaic power generation technology , Increasing investment in photovoltaic power generation technology , Developed countries have long paid attention to the use of photovoltaic power generation technology , However, although China's starting time is over , However, China's photovoltaic power generation industry is also developing rapidly , It has become the leader of the global photovoltaic industry , With the update of some key technologies of photovoltaic power generation last year , The cost of photovoltaic power generation is greatly reduced , Last year, China began to recommend the photovoltaic power generation network access plan for rural houses , Push the development of photovoltaic industry to a climax !

Two 、 Principle of photovoltaic power generation and grid access
   Solar cell module converts solar energy into electric energy through photovoltaic power generation system and photovoltaic effect , Part of it is stored in the battery pack , Part of it is converted into sine wave by inverter AC220V AC power is used for daily load of residents , The surplus electricity is transmitted to the State Grid , At night, the electricity stored in the storage battery during the day can be used by residents' daily loads through the inverter , Photovoltaic is a good clean energy , No carbon emissions , No environmental problems . Photovoltaic grid connection requires a dedicated grid connected inverter to ensure that the output power meets the voltage requirements of the grid , Requirements for frequency and other performance indicators . The inverter is also the maximum power point tracking of photovoltaic array 、 Official grid connected waveform and power , Balance the maximum power generated by the photovoltaic array transmitted to the power grid .

3、 ... and 、 Photovoltaic power generation monitoring
  From the above principle, we can know , If we want to fully understand the operation of photovoltaic power generation equipment , efficiency , Power generation , We need to monitor the grid connected inverter , Barium rhenium Technology BL101 It can be well connected with inverter communication , Convert the waveform of the inverter , frequency , power , Power generation , Power generation quality , The conversion efficiency and other data are transmitted to the photovoltaic monitoring center , It can be displayed on the large screen , early warning , Cost calculation and other functions .
