Solar street lights make the city more intelligent     Safer, more efficient, smarter and more sustainable development    With the improvement of the quality of human life, the consumption of energy has also increased rapidly, and the earth ’s ecological environment has also deteriorated. Energy shortage and environmental pollution have become problems facing sustainable economic development.    According to statistics of relevant data, lighting consumption accounts for about 20% of global energy consumption. China ’s annual electricity used for lighting is more than 300 billion degrees, of which road lighting accounts for about 30% of total lighting. To achieve sustainable development, new The development of energy and the implementation of the concept of energy saving and emission reduction are particularly important.* The picture is from the Internet    First,Great innovation of traditional street lamps    Among the many energy consumptions, the consumption of lighting electricity is particularly prominent. According to data, lighting electricity accounts for 20% of the global total electricity consumption, but most of the lighting efficiency is very low. As the blood of the city, street lamps play a vital role in the construction of smart cities. With the widespread application of solar technology, the use of solar street lamps has gradually appeared in people's vision.    As a kind of sustainable renewable energy, solar energy has very attractive prospects for development and application, and it can be used wherever it is exposed to sunlight. The effective use of natural energy is the focus of today's new energy technology research. By collecting solar energy and recycling, it can save nearly ⅓ cost of lighting electricity every year. * The picture is from the Internet   Advantages of solar street lights:   1. Convenient installation: It integrates the installation of battery panels, photovoltaic panels, intelligent lamp holders, etc. No need to lay cables, just fix the cement base;   2. Low cost: natural energy is free of electricity charges, and there is no maintenance cost;   3. Security guarantee: It contains anti-theft brackets, which can intelligently regulate and control the current, and the security issues are guaranteed;   4. Long service life: The service life of solar panels is 25 years, the average life of ultra-bright LED lights is more than 50000 hours, and the life of solar batteries can reach 5-7 years.     Second,the secret of the core components of solar street lights    The core device of the solar street lamp is the controller . It is an intelligent charge and discharge device operated by a micro-control chip. Its main function is to control the charge and discharge of the solar battery to the battery. Rely on solar panels to absorb solar energy for energy storage during the day, and control the output current of the battery to the LED light source at night.    The  fourth-generation DM series of solar street lamp controller in SRNE  , has a maximum power tracking (MPPT) , it is to meet for solar street light controller all imagination, not only solved the problem of high electricity costs, but also ease The lack of power supply in remote areas is very popular in regions where power demand cannot be met.* The picture shows the SRNE solar controller DM120-W    SRNE solar controller features:    1. Lithium battery precharge technology . When charging for the first time, the controller will pre-charge the lithium battery. When it is judged that the lithium battery can be charged, the charging current will gradually increase for charging    2. Constant voltage activation technology . If it is judged that the lithium battery is not charged, the controller will activate the lithium battery; if the lithium battery has been unable to activate the charging, it will output a constant voltage to the lithium battery instead of the battery board voltage connected to the lithium battery, causing lithium battery or protection board In a dangerous voltage range;    3. High-precision voltage stabilization technology . Using current and voltage dual-loop control, when the battery panel power changes rapidly (such as cloudy weather), the battery voltage remains stable, there will be no glitches or voltage jitter, to prevent instant high-voltage charging of lithium batteries    4. Voltage and current ripple control technology . Optimize the main circuit design to further reduce the voltage and current ripple during charging, and prevent the overcharge protection of the lithium battery protection board from being triggered by mistake; ...

'The application field is more extensive'   Solar charge and discharge controllers are indispensable in photovoltaic systems that protect the battery from overcharging and over-discharging, and extend battery life.    It is mainly based on off-grid power generation system, which is light, flexible and convenient to carry. It mainly serves remote mountain areas, pastures, deserts, islands and border posts that are difficult to be covered by the public power grid. It provides basic lighting, television, radio, etc. Life electricity. Note: The picture shows the Poverty Alleviation Project of SRNE Solar Controller in Northwest China     With the advent of the Internet era, the functions of solar controllers are becoming more and more powerful, and are gradually used in various fields such as Bluetooth communication, RV, remote control, and poverty alleviation. Note: SRNE Solar Controller is used in RVs'The control technology is more advanced'   The working parameters of traditional solar controllers have been set, and the power transfer of the solar panel in a constant voltage and constant current mode will not change according to the changes of the surrounding environment, thus causing the battery to never be fully charged. The solar panel It has not been fully played.    In order to solve this problem, SRNE is also constantly exploring and researching on the technical level of the solar controller, from the first generation controller pulse width modulation (PWM) technology to the second generation maximum power point tracking (MPPT) technology The control is more stable, the ability to intelligently regulate changes in the working environment is stronger, and it is more suitable for areas with harsh conditions. Note: SRNE Solar Controller and border defense cooperation   The new generation of solar charge and discharge controller can perform real-time intelligent charge and discharge control according to solar cells, batteries, light sources and other components; according to factors such as seasons, environment, light changes, etc. to determine different working modes of charge and discharge, so as to improve The stability and intelligence of the solar controller are more suitable for areas with harsh conditions.'Home application is more appropriate'    SRNE is committed to using solar charge and discharge controllers in combination with homes, so that people can enjoy the convenience of solar energy at home.    The ML series of solar charge and discharge controllers mainly serve indoor homes. They can not only intelligently regulate the energy absorption state of electric panels according to the environment, but also significantly improve the energy utilization efficiency of photovoltaic systems. When the temperature exceeds the set value of the device, the charging current is linearly decreased with the temperature and the discharge is turned off, thereby reducing the temperature rise of the controller and avoiding high temperature damage of the controller.Note: Schematic diagram of solar controller home          'If you want the solar system to exert its maximum efficiency and value, the choice of a good solar controller is the most critical factor. And SRNE is committed to creating the industry's top controller research and development to meet various applications of the controller. Future development can be Period, I invite you to witness together. '
