Solar power plant system consists of solar cell array, combiner box, DC distribution cabinet, grid connected inverter, distribution cabinet AC and a booster. In photovoltaic solar power generation systems, combiner boxes are used, also known as solar combiner boxes, solar photovoltaic combiner boxes, photovoltaic array lightning protection combiner boxes, solar power generation combiner boxes, photovoltaic power generation combiner boxes and photovoltaic lightning protection combiner boxes. In solar photovoltaic power generation systems, a combiner box is used to reduce the connection between the solar photovoltaic cell array and the inverter.
Solar power plants using micro-wavesThey do not need to use a combiner box because the microinverter is matched to each battery. In many cases it is necessary to provide 220VAC and 110VAC AC power. Because direct solar power generation is usually 12V DC, 24V DC or 48V DC. In order to power 220V AC electrical appliances, the DC power generated by the solar power generation system needs to be converted into AC power, so a DC-AC inverter is required. In some situations, when multiple voltage loads must be used, a DC-DC inverter is also used, for example to convert 24 V DC power to 5 V DC power (note that this is not of a simple step-down).
Microinverters can be used in small and medium-sized rooftop solar power plants, such as homes, schools and factories. Microinverters have the characteristics of an installationflexible and convenient ion, high power generation performance, high safety factor, high intelligent management and low maintenance costs. The first domestic microinverter enterprise that develops and owns independent intellectual property rights is Yingweili New Energy Technology (Shanghai) Co., Ltd., located in Zhangjiang High-Tech Park in Shanghai. Yingweili microinverters and intelligent monitoring equipment produced are mainly. in Europe.
