This site provides information such as LED street light knowledge, new energy LED light design, outdoor street light Installation and maintenance, etc.
Do you know the solar resources and solar cells ? We will introduce new energy LED street lamp energy storage and control technology
The main difference between new energy LED street lamp and conventional street lamp is the different power supply. The power supply system of new energy LED street lamp is composed of solar cell module, wind turbine, battery and controller, which brings great difficulties to daily maintenance because of its standard, component quality and installation method. […]
The management and maintenance of urban lighting facilities are of great significance and considerable economic value and social value, and the more important in the world of energy shortage today. Urban lighting facilities can only maintain continuous and effective work under good maintenance conditions. If it is not well maintained, it will increase the aging […]

1) Wind power charging control unit The function of the wind power generation charging control unit is to control the charging of the battery by the wind power generator to ensure that the battery is not overcharged or overdischarged, so as to ensure the normal use of the battery and the reliable operation of the […]
Main features of EPDC type solar power dual output controller The main features of the EPDC type solar power dual output controller are as follows.(1) A single-chip microcomputer and special software are used to realize intelligent control.(2) Accurate discharge control is realized by correcting the discharge rate characteristics of the battery. The discharge termination voltage […]
The solar LED street light controller is the most important component in the solar LED street light system, and it is also the biggest difference from various street light systems. The performance of the controller design determines the pros and cons of the operation of the solar LED street light, so it is very important […]
PV controller hardware structure The hardware structure of the photovoltaic controller is shown in Figure 1. The controller uses AVR mega32 microprocessor as the control core. The peripheral circuits are mainly composed of battery voltage and ambient temperature detection and charge and discharge control circuit, solar cell voltage detection and group switching circuit, Load current […]
Working principle of photovoltaic controller The output characteristic curve of the solar cell is shown in Figure 1. The volt-ampere characteristic of the solar cell has a strong nonlinearity, that is, when the sunlight intensity changes, its open circuit voltage will not change much, but the maximum current generated will There is considerable variation, so […]
In the mid-19th century, the advent of lead-acid batteries solved the problem of random power consumption of some electrical equipment. But after more than 100 years of development, its working principle has basically not changed. The chemical equation of its normal charge and discharge is:PbO2+2H2SO4+Pb↔2PbSO4+2H2O The above normal charge and discharge chemical equations are idealized […]
