FAQ

What are the requirements of electrolytic capacitors for PV solar inverter?

As an important part of photovoltaic power generation, the main function of solar inverters is to convert DC from photovoltaic modules into AC. So, what are the requirements of electrolytic capacitors for photovoltaic solar inverters?

High voltage. General high-power photovoltaic solar inverters incorporate the converted AC directly into the high-voltage power grid, but from the safety point of view, the output voltage of photovoltaic battery pack is generally not higher than 900V, two 450V electrolytic capacitors can be selected in series, but in order to improve security, two 500V electrolytic capacitors can be selected in series. Therefore, high voltage capacitors are needed to reduce the series connection of capacitors and improve reliability.
High ripple resistance. In general, the current flowing through capacitors of photovoltaic inverters is 0.44 times of the effective value of the output current of the inverters. For example, the output voltage of photovoltaic inverters is 250V, the output current corresponding to 1 kW output power is about 2.54A, and the current flowing through DC bus capacitors is 1.12A. DC bus capacitors of 100 kW PV solar inverters need to flow through 112A RMS current. The rated current of the selected capacitors should not be lower than this value. If the rated current of an electrolytic capacitor can not meet the requirements, it is necessary to select multiple electrolytic capacitors in parallel to obtain the required current value. Therefore, a single electrolytic capacitor with high ripple resistance is required to reduce the number of parallel electrolytic capacitors and improve the overall reliability.

Nice product, would be nice to have a better deal on the price!

This 4000w off-grid solar inverter handles all my appliances smoothly with pure sine wave output, and the LCD keeps me updated on voltage and battery status clearly. It’s built tough for all temperatures—just wish the price was a bit lower.
