Rural solar street light system, based on the photocurrent power inverter control of solar panels and batteries, as well as between the load current, the output of solar panels of the dc voltage is converted into a large clean 50 hz or 60 hz sinusoidal current, lose
rural solar street lamp based on the photocurrent 【 Circularly polarized light make absorb indoor atomic magnetic moment, orientational then absorbed by the helium lamp can light through the lens converge on exposure to light sensor, form the photocurrent. 】 System, power inverter 【 Power inverter ( Car power) Is a kind of can convert DC12V direct current to the same AC220V ac mains, and for the use of general electric, is a convenient power supply converter. 】 Controlling the solar panels and batteries, as well as between the load current, the solar panels of the output of the dc voltage is converted into a large clean 50 hz or 60 hz sinusoidal current, output to load or feedback to the grid. Shows the important effect of inverter in solar power.
due to the output voltage is changing solar panels, to keep generating electricity as efficient as possible is very complex. To accomplish this task is the key to detect maximum power point ( 最大功率点,MPP【 MPP is a kind of English abbreviations, can say a lot of word meaning, such as a master's degree, biological terms, industrial raw materials, mobile power supply, etc. , can also be said that the Project of a kind of file format. 】 ) 。
MPP tracking technology can be used to detect the MPP, and adjust the output voltage of DCDC conversion, in order to maximize the output. MPP tracking can increase the overall efficiency of the solar cell system in winter 13 or more, and then it is also the highest power demand.
controller to determine the most commonly used algorithm of MPP is the working voltage of solar panels, and detect the output. Algorithm to around the MPP point set aside a large enough range of oscillation, avoid when the sky and the cloud controller issue wrong disturbance to the local power supply.
