What kind of battery is used for solar street lights, and where is the home solar street light batte

Generally, maintenance-free batteries are used, lead-acid, colloidal are useful, and lithium batteries can also be used if conditions permit, mainly for voltage matching.

The following points should be paid attention to in the installation of solar street lights:

1. Have a comprehensive understanding of the characteristics of solar street lamps, light sources and light poles, and reasonably select solar lamps, light sources and light poles according to the actual and reference lighting standards of the road, combined with the investment budget, so as to give full play to the high efficiency and energy saving of the light source, the light distribution of solar lamps and lanterns, and the advantages of accessories combination.

2. Under the condition of guaranteed light performance, appropriately increase the spacing of solar street lamps and lanterns to save the number of lamps and lanterns; Appropriately increase the height of the solar street lamp pole to improve the lighting effect; As far as possible, the pole is separated in the middle of the road to save the project cost.

3. Combined with road engineering, intervene in pole position selection, foundation construction and pre-embedding in advance in a timely manner, so as to find problems in time, make reasonable changes, ensure quality and save investment.

4. According to the actual and geological conditions of the solar street lamp engineering site, design and manufacture the solar street lamp pole foundation and high pole lamp foundation to ensure that the foundation is firm and reliable. Special attention should be paid to the adaptation of the embedded bolt and the reserved hole of the rod base, the accurate positioning, the embedded length and the remaining length are reasonable, and the threaded part should be properly protected to facilitate hoisting and positioning.

5. In the rock formation, weathered stone section, it is difficult to meet the requirements of dispersed grounding and segmented grounding, and it can be considered to connect the conductors such as galvanized flat steel according to the design requirements, and the connection should be reliable, and at the same time be appropriately protected, and be reliably connected with the embedded foundation to ensure that each light pole is reliably connected with the ground. The high pole lamps in the solar street lamps are more scattered, mainly relying on the foundation grounding, and if necessary, the resistance reducing agent should be used to reduce the grounding resistance.

6. The hoisting operation should strictly abide by the operating procedures. In particular, it is necessary to pay attention to the power grid lines and other lines around the hoisting equipment, as well as the surrounding structures, and the hoisting point should be reasonable when hoisting, and the positioning should be adjusted in time.

7. Pay attention to the beauty of the solar street light pole after installation. From the beginning of foundation construction, the light position is subject to the main line to control the linearity, and reasonably change the line shape according to the road design, the light pole is straight, the processing weld and the maintenance port should avoid the main direction, and the whole line is consistent. The inclination angle of the cantilever of the light pole should maintain the coordination of direction and angle.

8. The plug-in parts of the internal accessories of solar street lamps and lanterns should be plugged in tightly and firmly to avoid failures caused by loose wind swing and poor contact. Solar street lamps and lanterns are reliably fixed with light poles, light poles and cantilever arms. The high pole lamp in the solar street lamp should be set in place, the lifting frame and the lamps should be reliably fixed, the lifting system should be safe and reliable, and the functions of lifting, limiting, positioning and so on should be complete.

The price ratio of a little higher solar street lamp battery is still recommended that you go to Huangchuan Limin Science and Technology Street Lamp Factory according to your situation one-to-one customization, customized under the same quality, ** is relatively favorable.

Solar street lights are a type of lighting equipment that uses solar energy to generate electricity, which converts solar energy into electricity through solar panels, and then stores the electrical energy into a battery for night lighting. When choosing a battery for solar street lights, you need to consider the following factors:

1.Capacity: The capacity of the battery determines the amount of electrical energy that the solar street light can store. Generally speaking, the larger the capacity, the longer the illumination time of the solar street light.

2.Cycle life: Batteries for solar street lights need to be charged and discharged frequently, so cycle life is an important consideration. The longer the cycle life, the longer the battery life.

3.Charging efficiency: The battery of a solar street light needs to be charged by a solar panel, so charging efficiency is an important indicator. The higher the charging efficiency, the faster the solar street lights will be charged.

4.Safety: The safety of the battery is an important consideration. The battery of the solar street lamp needs to have safety protection functions such as preventing overcharge, overdischarge, and short circuit to ensure safety during use.

At present, the commonly used solar street light batteries mainly have the following types:

1.Lead-acid battery: Lead-acid battery is one of the most widely used solar street light batteries. It has a high capacity and cycle life, and at the same time, it is relatively low, so it is widely used in solar street lights.

2.Lithium-ion batteries: Lithium-ion batteries have high energy density and cycle life, while being smaller in size and lighter in weight. Due to its superior performance, lithium-ion batteries have been applied in some high-end solar street lights.

3.NiMH battery: NiMH battery has a high cycle life and a low self-discharge rate, and is environmentally friendly at the same time. Due to its stable and reliable performance, nickel-metal hydride batteries have been used in solar street lamps in some special environments.

In general, the choice of battery for solar street lights should be determined according to actual needs and budget. Different types of batteries have different characteristics and scope of application, which need to be selected according to the specific situation.

The battery of the solar street lamp is generally placed in the buried box as the coarse energy component of the solar street lamp system, and the buried box is generally placed in the cement pool specially built next to the lamp pole, and the battery is very important to do a good job of heat preservation and air dissipation and waterproofing. There are also some solar street lamps in the south, and the battery can also be placed in the specially welded battery box at the bottom of the light pole, which is very convenient to disassemble, but it has an impact on the life of the battery under high temperature conditions.

[18V70W] solar panels can be used. Solar LED Light Calculation:

Lamp power: 20W, the average daylight time in a place for many years is 6 hours.

Lighting requirements: 10 hours per day, 3 consecutive days of lighting, 12V system.

Calculation process: (1) Daily electricity consumption of lamps:

20w*10h=200wh

Battery capacity:

200Wh 12V * (3+1) days = 67Ah Considering the efficiency and depth of discharge, the efficiency is calculated as 90%, and the battery discharge depth is calculated as 80%, then the capacity of the battery should be:

66 According to the battery specification 12V100Ah.

2) Solar panel calculations.

Battery discharge per night = 200wh 12v =

Charging current of the battery board = is the coefficient, about more rainy days, the larger the coefficient, and vice versa, generally between) The power of the battery board = 18V*.

Therefore, [18V70W] solar panels can be selected.

To calculate the configuration, you first need to know a few conditions.

1. The specific location of the lamp installation, xx province and xx city. The main purpose is to check the solar light situation;

2. What is the power of the lamp;

3. Lighting for a few hours every night;

4. Ensure that you use a few rainy days.

The solar street light should be equipped with a 92ah battery and an 18v 70w panel.

Advantages of solar street lights:

1.Easy installation: When installing solar street lights, there is no need to install complex circuits, only make a cement base, make a battery pit, and fix it with galvanized bolts.

It does not need to consume a lot of manpower, material resources and financial resources, and the installation is simple, and there is no need to erect wires or "disembowel" to dig the ground, and there is no worry about power outages and power rationing.

2.Less investment: one-time investment in solar street lamps, long-term benefits, due to the simple line, no maintenance costs, no expensive electricity. 6-7 years to recover costs, 3-4 years to save more than 1 million electricity and maintenance costs.

3.Good safety performance: due to the use of 12-24V low voltage, the solar street lamp has stable voltage, reliable operation, and no potential safety hazards, which is an ideal product for ecological communities and road administration departments. There are no accidents such as electric shock and fire.

4.Energy saving and environmental protection: Solar photovoltaic conversion provides inexhaustible electricity.

No pollution, no noise, no radiation. Solar street lamps can add new selling points to the development and promotion of noble ecological communities; Continuously reduce the cost of property management and reduce the cost of the common share of the owner.

First, calculate the load current.

For example, if there is a 12V battery system and 2 LED street lamps with 40W lamps, the load power is 80 watts.

Load current 80W 12V A

Second, secondly, calculate the battery capacity, such as: the cumulative lighting time of the street lamp per night needs to be 7 hours (h) at full load 1, such as 8:00 at night, 11:00 at night

Route 1 closes at 30, Route 2 opens at 4:30 a.m., and closes at 5:30 a.m.

2. It needs to meet the lighting needs of 5 consecutive rainy days. 5 days plus lighting the night before the rainy day, 6 days are counted. 3. Battery 7h (5 1) days.

42H280 AH4, in addition, in order to prevent the battery from overcharging and overdischarging, the battery is generally charged to about 90; The discharge is left about 20. 5. So 280ah is only about 70 of the real standard in the application.

3. Calculate the peak demand (WP) of the panel

1. The cumulative lighting time of street lamps per night needs to be 7 hours (h); 2. The average daily effective light receiving time of the battery panel is one hour (h);

3. At least relax the reservation amount of 20 for the demand for battery panels.

wp÷＝（7h × 120％）÷

Therefore: the peak value of the solar panel is:

wp ＝ 217（w）

Solar lights use lithium-ion batteries to install convenient When installing traditional solar street lights, a battery pit should be reserved and the battery should be placed in the underground box to seal.

The installation of lithium solar street lights is more convenient, and the lithium-ion battery can be installed directly on the bracket, using the hanging or built-in type. Lithium-ion solar street lights are easy to maintain. Lithium-ion solar street lights only need to take out the batteries on the power poles or panels during the maintenance process.

Lithium-ion characteristics.

Lithium-ion batteries are small in size, light in weight, and easy to transport. Compared with lead-acid gel batteries for solar street lamps of the same power, the weight is about one-third and the volume is about one-third. Therefore, shipping is easier, and shipping costs naturally go down.

Lithium-ion batteries have high energy density and long life. Energy density refers to the amount of energy stored within a certain unit of space or mass.

The same goes for the battery of the lithium-ion battery assembly device solar led street light, which is also used to store electricity and lighting. Its types generally include lead-acid batteries, nickel-cadmium batteries, and nickel-metal hydride batteries. However, in street lighting, colloidal lead-acid batteries are used more.

It can meet the premise of night lighting, store the energy generated by solar energy during the day, and store energy to meet the lighting needs of continuous rainy night lighting.

There are many more details, let's make it simpler!

The main components of solar lights are solar panels, controllers, batteries, and how long does the battery you are asking last depends on the following points:

1.The length and intensity of sunlight exposure (depending on the region, such as sunny in the north and rainy in the south).

2.The conversion rate of solar panels into electrical energy after absorbing sunlight depends on the quality of the panel3Whether the controller can control the power supply with high efficiency and energy saving, the person who will save money will have money4Whether the luminaires used are energy efficient (LED) or not

When the battery is placed in the control box, it must be handled with care to prevent smashing the control box;

The connecting wires between the batteries must be bolted against the binding posts of the batteries and copper gaskets must be used to enhance the conductivity;

After the output line is connected to the battery, it is forbidden to short-circuit under any circumstances to avoid damaging the battery;

When the output line of the battery is connected to the controller in the pole, it must pass through the PVC threading pipe;

After the above is completed, check the wiring on the controller side to prevent short circuits. Close the door of the control box after normal.

Put the battery into the battery box, and connect the connecting wire to the controller according to the technical requirements;

First connect the battery, then the load, and then the solar panel;

When wiring operation, it must be noted that the wiring and the terminal marked on the controller cannot be connected wrong, and the positive and negative polarities cannot collide or be reversed;
