Solar inverters can also be referred to as photovoltaic inverters ,It is a type of power inverter which converts the variable direct current (DC) output of a photovoltaic solar panel into a utility frequency alternating current (AC) that can be fed into a commercial electrical grid or used by a local, off-grid electrical network. It is a critical balance of system (BOS)–component in a photovoltaic system, allowing the use of ordinary AC-powered equipment. Solar power inverters have special functions adapted for use with photovoltaic arrays, including maximum power point tracking and anti-islanding protection.
1. Control unit: The inverter control unit is mainly composed of electronic components such as processors, clocks, and drive circuits. The main function is to control and adjust each component inside the inverter. The performance of the inverter control unit determines the overall stability and accuracy of the inverter.
2. Rectifiers: The rectifier unit usually uses a silicon flow diode or IGBT component. Its main function is to convert the input DC power into DC power supply to provide a stable power supply for the inverter circuit.
3. Reverse unit: The inverter unit is one of the core components of the inverter circuit board. It is mainly composed of electronic components such as semiconductor components such as IGBT. Operating analog load.
4. Output filter: The main function of the output filter is to cut the AC waveform of the inverter output for peak-cut valley and eliminate harmonics to ensure that the AC power of the inverter output has a stable voltage, current, and frequency, and meets satisfaction. Requirements for power loads.
