The influence of the rated output power of the photovoltaic inverter on the solar street lamp1

Photovoltaic inverters are the main components and important components of solar power generation systems, as well as important components in solar lighting systems such as solar street lights. In order to ensure the normal lighting operation of solar street lights, the correct configuration and selection of photovoltaic inverters is very important. It's important. The configuration of the inverter should be determined according to the various technical indicators of the entire solar street lighting system. Generally, the following technical indicators should be considered: 　　Rated output power indicates the ability of the photovoltaic inverter to supply power to the load, and the rated output power is high. Photovoltaic inverters can carry more electrical loads. When choosing a photovoltaic inverter, you must first consider equipment with sufficient rated power, so that it can meet the electrical power requirements of the equipment under the maximum load, as well as the expansion of the system and the access of some temporary loads.　　The adjustment performance of the output voltage represents the regulation ability of the output voltage of the photovoltaic inverter. Generally, photovoltaic inverter products give the percentage of fluctuation deviation of the output voltage of the photovoltaic inverter when the DC input voltage changes within the allowable fluctuation range, which is usually called the voltage regulation rate. High-performance photovoltaic inverters should also provide the deviation percentage of the output voltage of the photovoltaic inverter when the load changes from zero to 100%, which is usually called the load regulation rate. The voltage regulation rate of a photovoltaic inverter with good performance should be less than or equal to ±3%, and the load regulation rate should be less than or equal to ±6%.　　The efficiency of the whole machine represents the size of the power loss of the photovoltaic inverter itself. For photovoltaic inverters with larger capacity, the efficiency values u200bu200bfor full-load and low-load operation should also be given. The efficiency of the inverter has an important impact on the solar street lighting system to increase the effective power generation and reduce the cost of power generation. Therefore, when choosing a photovoltaic inverter, comparison should be made as much as possible to choose a product with higher overall efficiency.
