Photovoltaic inverter dedicated

Photovoltaic inverter (Photovoltaic Inverter) is an important equipment to convert the direct current generated by solar photovoltaic panels into alternating current. Aluminum electrolytic capacitors play the role of filtering, energy storage and voltage stabilization in photovoltaic inverters. Choosing the right capacitor is very important to improve the efficiency and life of photovoltaic inverter.

Key parameters and characteristics

Capacitance and withstand voltage：

• capacitance: Select the appropriate capacitance according to the circuit design, usually ranging from hundreds of microfadas to thousands of microfadas.
• Withstand voltage value: Choose a capacitor whose withstand voltage value is 20-30% higher than the actual working voltage to ensure safety and life.

Low ESR (equivalent series resistance): Low ESR capacitors can reduce power loss, improve power efficiency, and better filter out high-frequency clutter.

High ripple current capability: The photovoltaic inverter needs to deal with large current fluctuations, and the capacitor with high ripple current capacity can withstand these fluctuations and improve the stability and reliability of the system.

Temperature stability: Choose capacitors with a wide temperature range (such as -40°C to 105°C or higher) to ensure stable operation in high temperature and harsh environments.

Long life and high reliability: Photovoltaic inverters require capacitors to have a long life (such as 5000 hours or longer) to ensure long-term stable operation of the equipment.
