Why do photovoltaic panel street lights use four pin sockets?

The main reasons for using four-pin sockets for photovoltaic panel street lamps are as follows:

1.Power supply**: Photovoltaic panel street lights are powered by converting solar energy into electrical energy through solar photovoltaic panels, so a power supply ** interface is required. The four-pin socket provides a power input to feed solar energy into the street lighting system.

2.Data transmission: Photovoltaic panel street lights usually also need to carry out data transmission, such as monitoring the current, voltage and other information of the solar panels, as well as controlling the switch, brightness and other parameters of the street lights.

The four-pin socket provides a data transmission interface to transmit this information to the street light system.

3.Waterproof and dustproof: Photovoltaic panel street lights are usually installed in outdoor environments and need to have certain waterproof and dustproof performance. The four-pin socket can be designed as a well-sealed interface, which can effectively prevent water and dust from entering the socket and ensure the normal operation of the street lighting system.

4.Safety: The four-pin socket provides a high level of safety to avoid current short-circuits or other electrical problems. The design of the socket can ensure the stability of power supply and data transmission, and reduce the occurrence of circuit faults.

In general, the use of four-pin sockets for photovoltaic panel street lights is to meet the requirements of power supply**, data transmission, water and dust resistance, and safety. This socket design can ensure the normal operation of photovoltaic panel street lights, and provide a convenient interface for easy installation and maintenance.

Two power cords, two signal cables, do not light up during the day and only light up at night.

There should be a controller between the lithium battery and the lamp head, open it to see, the output end is generally marked with the name of the lamp, battery, solar energy, or wiring diagram, look at the color of the output line to judge the positive and negative poles.

Maybe the battery is broken, try the battery voltage, take it apart and take off the battery to charge it.

Change the battery, try whether the photovoltaic panel is charged, and check whether the circuit and circuit board control board are obviously abnormal.

Check whether the photovoltaic panel has output, open circuit voltage, short circuit current, and the photovoltaic panel is not burned out, and it can be charged.

The controller circuit can also be damaged. Be waterproof and moisture-proof.

All kinds of situations are possible, if there is a multimeter to measure it can be known, if you measure the photovoltaic panel, disconnect other circuits to measure the output voltage, you can roughly understand the quality of the photovoltaic panel, because the contact part of the wire in the air will oxidize, poor contact is also possible. Turn on the circuit and measure the voltage of the photovoltaic panel again, if the voltage drops or the photovoltaic panel, if the voltage does not drop, it is basically a line problem, and so on.

The size of the photovoltaic panel of the solar energy street lamp is mainly related to the power of the street lamp head and the time of the lamp, which is calculated.

Usually. Under the DAO, 6 meters of 30W are generally configured with 60W boards, and 8 meters of 50W are generally configured with 80W boards.

In practice, the configured board is generally slightly larger than the calculated theoretical value, which is mainly due to the fact that it can be charged better on rainy days. DZ Jiuneng New Energy.

Hello! This main copy depends on how high the light pole is related to the **, built.

The discussion is as follows: if the height of the light pole is then you can use an 8w garden light; If the height of the light pole is 3m, then you can use a 12w solar garden light; If the light pole is 5m then you can use 15w or 21w solar street light, if the light pole is 6m then use 28w or 30w can do, if the light pole is 7m then use 40w solar street light, if the light pole is 8m then you can use 56w or 60w solar street light, if it is 10m then you use about 80w solar street light, 12m or so you can use 100w No matter how tall the light pole is, it is recommended that you do not install solar street lights.

The voltage output of the photovoltaic panels of solar street lights is based on the voltage of the battery.

A normal 12V battery needs a photovoltaic panel with a working voltage of 18V to charge.

Don't need other equipment, just plug in the line and bask in the sun. You give a **note about the size, such as the area of the panel, voltage, and current, and then tell you how long it takes to fully charge.

Buy a 12V controller and you're good to go. Controller with solar panel and 12V battery.

Cranes, adjustable wrenches, hexagon wrenches, screwdrivers, cables, wire strippers, insulation, waterproof tape.

The parallel voltage does not change. The controller is 24V, so the two batteries should be connected in series, which is 24V, and the two photovoltaic panels are also connected in series to 24V

Need to know your lamphead power, how many hours you work every night, how many days to consider on rainy days, installation area, etc.

20 watt photovoltaic panel peach street lamp integration is a new type of street lamp design, it uses 20 watt photovoltaic panels as the energy source, and at the same time combines the design of peach street lamp, so that the street lamp has higher energy efficiency and more beautiful appearance.

First of all, 20 watts of photovoltaic panels are used as an energy source**, which can convert solar energy into electricity and supply street lights for lighting. Compared with traditional street lights, it does not require an external power supply, does not produce additional energy consumption, reduces dependence on traditional energy, and reduces energy consumption and pollution.

Secondly, the 20-watt photovoltaic panel peach street lamp integrates the design of the peach street lamp, which makes the street lamp have a more beautiful appearance. Peach street light is a unique street light design, its lampshade takes on the shape of a peach, giving people a warm and cute feeling. Combining 20 watt photovoltaic panels with peach street lamps can not only realize the use of green energy, but also increase the aesthetics of street lamps and add a beautiful landscape to the city.

In addition, the 20 watt photovoltaic panel peach street lamp has some other advantages. First of all, it has an automatic sensing function, which can automatically adjust the brightness according to the change of light, saving energy and meeting the lighting needs of different scenes. Secondly, it has the characteristics of waterproof, dustproof, anti-corrosion, etc., which can adapt to various harsh environmental conditions, and improve the service life and stability of street lights.

Finally, it also has an intelligent control system, which can realize the on/off and brightness adjustment of street lights through remote control, which improves the management and maintenance efficiency of street lights.

In a word, the 20 watt photovoltaic panel peach street light is a street light design with high energy efficiency and beautiful appearance. It uses photovoltaic panels to convert solar energy into electricity, which does not require an external power source, reducing energy consumption and pollution; At the same time, it combines the design of peach street lamps to increase the aesthetics of street lights. In addition, it also has the characteristics of automatic sensing, waterproof and dustproof, etc., which improves the service life and stability of the street lamp.

Through the intelligent control system, the remote control of the street lamp can also be realized, which improves the management and maintenance efficiency of the street lamp. This street lamp design is expected to be widely used in urban road lighting and contribute to the city's lighting industry.

The 20-watt peach lamp is usually wall-mounted and beautiful, and the 365 day light is <>
