The cold air that swept across the country has finally recovered. Think about the rumbling of cold air one after another. Can PV inverters outdoors withstand the cold wave?
It is understood that the lower limit of the operating temperature of photovoltaic inverters depends mainly on the operating temperature of internal IC components, such as IGBT single-tube, DSP chips and electrolytic capacitors. In general, the IGBT operating temperature range is -55°C to 150°C. The minimum operating temperature of the CUP chip, which has an important influence on the performance of the inverter, also starts at -40°C. The electrolytic capacitor that has a critical influence on the service life of the inverter is more sensitive to temperature. Whether the ambient temperature is too high or too low will cause the capacity to decrease or even damage, so the photovoltaic inverter can be extremely cold. The normal operation of the environment, the choice of components plays a decisive role.
Here is an architectural company in Ulanhot, Inner Mongolia. During the cold wave, the temperature here has dropped to -30°C. Even during the day, the ambient temperature is around -25°C. Is Sanjin Electric's 5kW PV inverter installed here normal? what about work?
It is understood that this photovoltaic power generation system was connected to the grid during the New Year's Day 2016, when the climate was extremely cold and cloudy. However, the system could still produce electricity normally every day, and the average daily generation capacity reached 15kWh. This made customers feel more surprised. This fully explains PV inverters can work normally in winter, and of course, whether they can operate normally, depending on the overall quality of the PV inverter.
With the country’s support for the photovoltaic power generation industry, photovoltaic power generation systems have entered more and more companies and households, and the number of photovoltaic products has a large number of brands and the quality is uneven. Therefore, when consumers choose products, they must go through multiple inspections. Selecting the right brand is a necessary condition for ensuring the long-term and continuous operation of the photovoltaic power generation system.
