With the increasing global emphasis on environmental protection, photovoltaic systems have been widely applied in various fields. In the electricity market, photovoltaic systems can not only supply power to cities, but also provide lighting and communication services for remote areas. At the same time, the installation cost and operating cost of photovoltaic systems are relatively low, which has attracted more and more attention from enterprises and government agencies.
Solar inverter is a device that converts the direct current generated by photovoltaic panels into alternating current. It monitors the voltage and current output by the photovoltaic panel through the Maximum power point tracking algorithm, realizes the rise and fall of DC voltage, and converts it into a stable DC power supply. Next, the inverter uses high-frequency pulse width modulation technology to convert direct current into alternating current, and smoothes it through an output filter to ensure the quality and stability of the output current. Ultimately, the inverter connects the output AC power to the power network to meet household or industrial electricity needs. In this way, Solar inverter plays a key role in converting solar energy into usable electric energy.
At present, the 1000~2200W Solar inverter commonly used at the input end of photovoltaic power generation system has an output voltage spike of 580V. However, the existing 500V output capacitance can no longer meet the demand of Solar inverter. Among them, Aluminum electrolytic capacitor plays a crucial role. It can not only provide necessary filtering and storage functions, but also ensure the reliability and efficiency of the whole system. If the output voltage is insufficient, it will cause the capacitor to heat up, breakdown, and ultimately damage. Therefore, various factors must be carefully considered when selecting Electrolytic capacitor, and the most suitable product must be selected to ensure the normal operation of the system and obtain the best performance.
In order to solve the high voltage problem of Solar inverter, Shanghai Yongming launched the high voltage lead type LKZ series Aluminum electrolytic capacitor. This series of products has precise performance characteristics and can operate over a wide range of input voltages, including peak voltages up to 580V. The excellent performance of LKZ series capacitors can improve the stability and efficiency of Solar inverter and provide customers with the best solution.
01. Super surge and impact resistance: LKZ series aluminum Electrolytic capacitor has a voltage of up to 600V, which can easily cope with peak voltage and large current during output.
02. Ultra low internal resistance and better low-temperature characteristics: Compared to Japanese capacitors of the same specification, the impedance of Yongming capacitors has decreased by about 15% -20%, ensuring that the capacitors have low temperature rise, resistance to large ripple, and low-temperature characteristics of -40 ℃ during operation, ensuring that the capacitors will not fail early in long-term operation.
03. Higher capacity density: Yongming aluminum Electrolytic capacitor has more than 20% more capacity than Japanese capacitors of the same specification and size, with higher capacity density and better filtering effect; At the same time, under the same power requirements, the use of Yongming’s Electrolytic capacitor with larger capacity can reduce the cost of customers in terms of capacitance.
04. High reliability: Yongming’s Electrolytic capacitor provides a more comprehensive guarantee for the stability and reliability of key electronic components such as Solar inverter, and makes the performance of the entire photovoltaic system more outstanding.
Yongming’s liquid lead aluminum Electrolytic capacitor, as a domestic innovative capacitor, has great advantages in the application of Solar inverter, providing a strong guarantee for the stability of photovoltaic system, and its comprehensive performance is comparable to that of Japanese capacitors.
