Electrolytic capacitor is also commonly used in photovoltaic inverter to achieve high efficiency filtering, which plays a key role in effectively filtering clutter in power supply through its unique charge storage and release mechanism. When there are clutter in the power supply input by the inverter, the filter capacitor can quickly capture and absorb these extra charges and store them stably in its internal structure, thus isolating the interference of clutter on the sensitive circuit inside the photovoltaic inverter
In the working process of the inverter, when the circuit needs extra charge to maintain a stable output voltage, the filter capacitor can immediately release the previously stored charge and provide necessary power support for the system
The general photovoltaic grid-connected inverter adopts metal shell or aluminum alloy shell, which has IP65 protection level and supports the working temperature of -40~65℃, meeting outdoor applications. The maximum output power of the inverter is 250W and the output voltage is 220V V. The maximum DC input voltage is 55V, which supports the maximum power tracking of 22-45V, and the maximum input current is 12A.
In addition, the maximum output power of the solar micro inverter is 250W, and it has a set of DC input and a set of AC input and output terminals. The inverter adopts an all-aluminum alloy shell to enhance the heat dissipation performance and reduce the temperature rise during operation. The inverter shell is fixed with screws, which is convenient for assembly and maintenance and improves the maintainability of products. Some inverters have built-in WiFi communication function, which supports web monitoring and APP remote monitoring.
Usually, these inverters need filter electrolytic capacitors to ensure the stability and purity of the output of photovoltaic inverters. Lorida electrolytic capacitors help the inverter to improve its overall performance and reliability. Common in-line filter electrolytic capacitors such as 63V 2200μF, 50V 3300μF, 450V 56μF, 63V 220μF and 450V 150μF are used in mainstream photovoltaic inverters.
With a number of enterprises entering the photovoltaic power generation industry, the competition in the inverter market is becoming increasingly fierce, and major manufacturers need to continuously improve the performance and quality of their products. With the continuous promotion of renewable energy policies and the growing market demand, electrolytic capacitors, as an indispensable part of the inverter's internal filter circuit, play a vital role in the overall performance of the inverter.
