Inverter measures to deal with high temperature weather
Na ka dina, E sega ni vaka kina. Na tubu ni livaliva ni photovoltaic power plants e vakadeitaki mai na vuqa na ka, ka okati kina na irradiance kei na ambient temperature. Na vulaikatakata katakata e dau salavata kei na katakata levu, sega ni levu na irradiance. The temperature characteristics of solar modules are negative temperature coefficients, kei na cakacaka ni vakatubu kaukauwa ni modules ena lutu sobu ni sa tubu cake na katakata. O koya gona, the peak power generation of photovoltaic power plants often occurs in late spring and early summer or late summer and early autumn. At this time, the ambient temperature is suitable and the irradiance is high, which achieves the best conditions for photovoltaic power generation.
In addition, the inverter is usually installed outdoors, even in direct sunlight, and the internal temperature of the inverter will increase accordingly in the high temperature environment in summer. The high temperature environment may also cause the inverter to over-temperature and load-drop protection, affecting the power station. power generation. O koya gona, the heat dissipation performance of the inverter is one of the important factors affecting the power generation efficiency and service life. Tarava, I will introduce how the inverter can better cope with high temperature weather.
1. Ensure air circulation
Ensure smooth air circulation around the inverter. Do not install the inverter in a small and closed environment. If multiple inverters are installed on the same plane, it is necessary to ensure that there is enough distance between each inverter. This not only It can ensure the ventilation and heat dissipation of the inverter, and there is enough operating space for later maintenance.
2. Avoid the wind and the sun
Secondly, although the protection level of the inverter is IP66 or IP65, it can reduce the chance of the inverter being exposed to wind, sun and rain, which can prolong the service life of the inverter. When installing the inverter, you can choose to install it at the bottom of the module or under the eaves. If the inverter is installed on the roof of the color steel tile, it is recommended to install the awning at the same time, which can not only shelter from the wind and rain, but also reduce the direct sunlight, reduce the temperature of the inverter, and avoid the load reduction caused by the over-temperature of the inverter. power generation efficiency.
3. Pay attention to post-maintenance
After the inverter is installed, it is necessary to pay attention to the later maintenance, and regularly clean the fan, fan cover or heat sink to ensure the heat dissipation and cooling of the inverter. Usually, the inverter will use intelligent air cooling technology to dissipate heat, and the fan will intelligently adjust the speed according to the internal temperature of the inverter. When the inverter works in a high temperature environment, the intelligent air cooling technology can effectively reduce the probability of load reduction. The inverter can run stably while extending the service life of the fan.
In addition, the inverter has a fan fault alarm function. The operation and maintenance personnel can receive the alarm information in the monitoring background, and quickly and accurately locate the fault, which is convenient for the operation and maintenance personnel to eliminate the fan fault in time, reduce the power generation loss, and ensure the power generation income.
