Guide to Buy Solar Energy Inverter in ALLTOP Lighting

In some places, the capacity of the photovoltaic system is according to the component to calculate system capacity, then according to the components of the actual output power to select the inverter, in order to avoid inverter current limit, according to the actual situation, the component and the inverter can be 0. 9:1 to 1. To configure 4-1. But the


in some places, pv systems system capacity is calculated according to the capacity of the component. At this point, the component based on the actual output power to select the inverter, so as not to limit current of inverter. According to the actual situation, components and inverter can be configured to 0. 9:1 to 1. 4:1. However, in some places, the system capacity is calculated according to the ac output power of inverter. If power selling prices are relatively high, and parts of relatively low price, you can increase the power of the component, in order to increase the output as much as possible. Components and inverter can be configured to 1. 4:4 to 1. 8:1, the number of components depending on the inverter can be connected. In the photovoltaic (pv) grid system, power inverter related components, components and inverter power match is not 1:1 fixed ratio, requires a combination of project specific situation into account. Main influence factors including the irradiance, system loss, efficiency of inverter, inverter, the inverter voltage range life, component installation Angle, etc. 1, component installation Angle, and azimuth Angle when the object plane vertical Yu Guangshi completely, the received power is very large. If the object is tilted, the plane form a certain Angle and light, the received power will be discounted. For the same area, the received power will be much smaller. Is the Angle between the vertical component and the sun, the power is very large. 2. Irradiance module power output of the installation area and irradiance. In solar energy resource-rich regions, due to the sunny days less cloud cover, air good air quality, atmospheric transparency is high, thus reach the surface of the module of solar radiation is much higher than average for resource-poor Settings. 3. The higher height of installation height empty, the rarer the air is, weaken the less solar radiation, atmosphere to reach the more solar radiation on the ground. For example, the qinghai-tibet plateau is a strong solar radiation area. The air is thinner, the inverter heat dissipation. If more than a certain height above sea level, inverter to reduce the speed of operation. 4. DC side system efficiency in the solar system, the energy from solar radiation to the photovoltaic module, and through the DC cable, junction box and reach inverter DC power distribution network, each link has a loss. Different design schemes, such as centralized, serial, distributed, etc. DC side loss, there are different. 5, inverter frequency converter cooling conditions should be installed in a well-ventilated place, avoid direct sunlight, is conducive to heat dissipation. If the inverter must be installed in an enclosed area for heat dissipation due to space limitation of, should consider to inverter derating problems, and should be equipped with fewer parts. 6. Power component is tolerance: in order to satisfy the photovoltaic modules 25 years attenuation is not more than 20% of the requirements, many components factory is 0 - for new delivery of the components 5% positive tolerance, such as 265 watts components, the new delivery of the components of the actual power may be 270 watts. 。 Negative temperature coefficient: parts of power supply system is about - temperature 0. 41%/℃。 When the component temperature drop, parts of power will increase. Sunny areas in China, such as northern ningxia, northern and southern xinjiang, gansu province, if you don't consider equipment loss, 250 tile module power output may be over 250 watts.

Solar lawn lights have been widely distributed and promoted, but everyone still has many questions about it. What are the three questions that they often encounter? Let the solar lamp factory lighting editor answer these questions for you. 1. What impact does the advancement of the boost circuit power have on the solar lawn lamp LED light? Low-power solar lawn lights usually have a boost circuit. If a vibration circuit is selected, an inductance boost is used. Standard color code inductors are used for the inductance, and open magnetic circuits are used in the standard color code inductors. The magnetic flux loss is large, so the circuit power is low. If a closed magnetic circuit is used to make an inductive boost, such as a magnetic ring, the power of the boost circuit will be greatly improved. The characteristics of the LED are close to the Zener diode, the operating voltage changes by 0.1V, and the operating current may change by 20mA. For safety, the use of series current-limiting resistors under normal circumstances, the huge energy loss is obviously not suitable for solar lawn lights, and the brightness of the LED changes with the operating voltage, and the current must be actively limited, otherwise the LED will be damaged. Usually the peak current of the LED is 50-100mA. If the high-energy battery is reversely connected or the battery is unloaded, the peak voltage of the booster circuit may exceed this limit and damage the LED. 2. What are the packaging methods for solar lawn lamp batteries? Currently, there are two main packaging methods for solar lawn lamp batteries, laminated and glued. Laminating technology can guarantee the operating life of solar cells for more than 25 years. Although the glue is beautiful at the time, the operating life of the battery is only 1-2 years. Therefore, low-power solar lawn lights below 1W can be packaged with epoxy without excessive life expectancy. For solar lawn lights with regular service life, it is recommended to use laminated packaging. 3. What is the process of turning on and turning off the solar lawn lamp? Solar lawn lights turn on and turn off lights are the process of gradual dimming. On the one hand, it can add solar lawn lights to illuminate, and on the other hand, it can control the uniform output current of the battery by changing the flashing duty cycle, extending the operating time of the system, perhaps under the same conditions , Can reduce the power of solar cells.
