Solar Inverter for Home Buying Guide

Because can intelligent control, solar street lamps in different period of time can realize automatic power adjustment according to the requirement, so the use of geographical and rated power is different.

Therefore, in different places have different standard of illumination, and blindly pursue high brightness, is not only waste, also may cause harm to people.

So, first to confirm the lighting requirements to choose solar street lamps to conform to his needs.

And solar street light price reflects the combination of cost, quality and brand value.

It is closely related to the configuration, super low price of led solar street light products inevitably there is no guarantee that use, but the super high price of solar street light system is certainly will appear beyond the requirement of configuration or artificially high component and a waste of money.

Because solar products have many advantages than ordinary products, whether national or ordinary people are willing to choose it, more important is environmental protection is very important, environmental protection is the most prominent advantages of solar street lamps, and now the most popular is environmental protection product.

Many cities have emerged to electricity agonies, that the main reason is caused by tight supply of domestic conventional sources of energy, it is only temporary for use less energy, but for a city, the long-term development of a country is not a good solution.

We need to do is to develop the use of renewable energy to replace conventional energy to save, solar garden light is the use of photoelectric conversion technology lighting equipment.

The use of solar energy can be infinite, and will not result in a waste of a kind of renewable energy, to use on the street lamp nature also brought a lot of benefits.

In the long run, the prospect of solar garden light is very good.

People's consumption in the first place is more practical, low cost, and the adoption of solar garden light is based on research and development of China's national conditions and customs, high cost performance.

According to the above said, solar garden light is necessarily will replace the use of conventional lamps city production, life, especially in energy, electricity and the electricity difficulties in remote areas, has a strong potential replication, use safety is also high, cities don't need electricity.

Led solar street lamps have long beyond the advantages of general road street lamp, solar lamp, though, the cost of solar energy lamp is general road lights of several times but, mid and late because no other power engineering to support it.

Believe in not long future, for the use of solar power will be more and more common, solar led street light will gradually melt into the general lighting.

But before that, we need to use led solar street lamps have a overall planning regulations.

Solar street lamps lighting the length is the key, therefore must equipment stability.

If the specification does not suit, is likely to cause internal road fault, solar led street light and even more serious things, before the operation, must check all the parts specification is to pass the exam.

The perspective of lithium battery components and slope is also very critical.

The key is the led solar street light solar equipment should be relevant to the various set in the regulations.

Otherwise, the loss is very simple manipulation, and there will be no shining lamp or lighting effects, for example, the abnormal phenomenon such as grey.

Other, apart from checking and maintenance parts, should also do a good job in lightning protection effect, immediately check grounding stationary situation, very is a summer thunderstorm, should take more attention to.

For the use of new energy scenery complementary street light, we think it is should be supported, should take the scenery complementary street light prices rather than as an excuse to think it's not worth to use, said although The Times the value of an item can't be embodies in the price of itself, but in many cases, the expensive things quality is more trustworthy than the cheap products, so the scenery complementary street lamps use itself is not in its own advantages compared with other think.

Besides, scenery complementary street light compared with ordinary mains street lamp, there is no comparability, in essence, though they both are as outdoor street light, but fundamentally they also only this same, is the nature of the different use.

From the analysis on their working principle, the ordinary street lamps need external electric power supply, and the generation of electricity is takes a lot of standard coal.

Is to rely on renewable energy and scenery complementary street lamps, rely on the rotation of the sun's light radiation and wind to produce electricity, zero emissions, zero pollution on energy use security environmental protection, ordinary mains street lamp is already can't compare with scenery complementary street lamp.

Not to mention the scenery complementary street lamp on the maintenance costs and electricity costs, these advantages are to compare other lamps.

The configuration of the solar street lamps calculation is how to calculate?
Calculation of current such as: 12 v storage battery;
2 only 30 w lamp, a total of 60 watts.

Present current = 60 w 12 v = 5 A capacity calculation such as street lamp lighting time every night.

5 hours, the actual lighting for 7 hours (full load
h)
;

Example 1:1 road




the configuration of the solar street lamps calculation is how to calculate?









calculate current

such as: 12 v battery'

Battery is a kind of chemical energy directly into electrical energy device, is designed according to the rechargeable batteries, rechargeable by reversible chemical reactions, usually is refers to the lead-acid battery, it is one of the battery, belongs to the secondary battery.
】
;
2 only 30 w lamp, a total of 60 watts.




present current = 60 w 12 v = 5 A


capacity


such as street lamp lighting time every night.

5 hours, the actual lighting for 7 hours (full load
h)
;




a: 1 road LED lights


(

If at 7:30 in the evening to open 100% power, the night 11 to 50% power, 100% power again after 4:00 in the morning, at 5:00 am close)




example 2:2 way the leds (
Low voltage sodium lamp, energy-saving lamps, energy-saving lamps, etc. )




(

As two road opened at 7:30 in the evening, night 11 close road 1, at 4 in the morning to open 2 road, 5:00 in the morning off)




need continuous rainy day lighting needs 5 days.
(

Plus 5 days before the rainy night lighting, 6 days)




= 5 a * 7 h * (battery
5 + 1)

Day


= 5 a * 42 h = 210 ah


in addition to prevent the battery charge and discharge, battery charge in general to around 90%;
Discharge the remaining 5%
About 20%.

So 210 ah really 70% - are just applications
About 85%.

Also, depending on the load, measure the actual loss, the actual working current affected by the constant current source, ballast, line loss, etc, may be on the basis of 5 a - 15%
About 25%.




peak


street lamp lighting of accumulative total of every night time need for 7 hours (
h)
;




u: panels accept effective illumination time is 4 a day on average.
5 hours (
h)
;




ease demand for panels 20% less reserved the forehead.
