Nanchang Ou Optoelectronics Technology Co., Ltd. The main products are: solar lights, solar garden lights, solar lawn lights, solar wind and solar street light series; a variety of LED light sources, solar PV modules, batteries, controller; various lampposts, garden poles, waterproof case and supporting the use of flip-flops, light control when the control switch and other electrical products. Solar lighting products are green, safe, energy-saving features. What solar controller solar controller is called the solar charge controller for solar power generation system, the control of multi-square solar cells to charge the battery and the battery power supply to the solar inverter load automatic control equipment. Solar controller used in solar photovoltaic products, which is responsible for the coordination of solar panels, batteries, work load and solar photovoltaic system controller is a very important component of the whole solar photovoltaic system efficient, safe operation. Solar controller usually has six nominal voltage rating: 12V, 24V, 48V, 110V, 220V, 600V solar controller three functions: 1. Power regulation: 2. Communication functions: simple indicator 2 protocol communication function such as RS485 Ethernet, wireless and other forms of management background. 3. Perfect protection: Electrical protection reverse polarity, short circuit, over current. Nanchang Ou Optoelectronics Technology Co., Ltd.

Solar lighting products are green, safe, energy-saving features. Note the use of the solar cell module 1. solar panels facing the square is usually placed equator, there is a certain angle relative to the ground plane. 2. Fixed area panels, and solar irradiance is proportional to the current and almost independent of temperature, and voltage (power) decreases with increasing temperature; general crystalline silicon plate voltage drop 0.5 / ℃, so the solar panels to be installed ventilated place, Gian solar lights, to keep cool, and a location Do not install too many components. 3. No part of the array of photovoltaic panels can not be shade, antique solar lights, solar panels if there is shade, solar lights tender, they will not produce and will form a reverse bias current, which means that the cover components consume power, heat, over time, the formation of the fault. (This is known as the heat island effect. Prevent heat island effect, generally inclined to put the solar panels, the solar cell surface can not be attached to the obstruction.) 4. inevitable occasional shelter, solar lampposts plant, since it is required bypass diodes protection. If all the components in parallel, you do not need a bypass diode; if required output voltage is 24V (or higher), you must have two (or more) modules in series, then you need to add a bypass diode to control the photovoltaic system current. Blocking diode can in each parallel branch, but also between the array and the controller dry road, but a number of branches and coupled into a large system, you should use on each branch in order to prevent the blocking diode slip fault or current shadowing caused by the strong current branch weak current flowing tributary of the phenomenon (the controller does not have this feature). Small systems in dry road with a blocking diode is enough, do not the two are used, because each diode will be down 6% 0.4 ~ 0.7V from a 12V system. Nanchang Ou Optoelectronics Technology Co., Ltd.

How easy it is to identify the quality of solar lights is the first thing we look at LED lamp emitting frequency and refresh rate, followed by emission luminance of the lamp is translucent. If it looks a bit dirty, it is likely that there is a problem of the quality of light. In addition, there is to look at the battery is good or bad. Of course, there is only the battery and solar street lights, so this is mainly for the solar street. Generally speaking good battery after it is fully charged can continue to supply a minimum of one week, of course, this time is not fixed (winter time may be shorter supply point). Of course, in addition to the above points outside there is a detail from the start to determine a more in-depth, such as the use of solar street light wires and so on. Solar Lampposts plant, Xinyu solar street much money, Gian solar lights provided by the EU can Optoelectronics Technology Co., Ltd. Nanchang. Nanchang Ou Optoelectronics Technology Co., Ltd. (www.okled.cn) is in Nanchang, Jiangxi, a leader in solar and renewable energy, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Optical leadership in Europe can with the staff warmly welcome all inquiries negotiations to create a better Europe can photoelectric future.
