Centralized Photovoltaic Inverters
Centralized photovoltaic inverters are the most commonly used inverter type in photovoltaic systems. They connect the DC power from multiple solar panels in parallel to a single inverter, which then converts the DC power into AC power. Centralized photovoltaic inverters have the following characteristics:
1. Large capacity: They can meet the needs of high-power power generation systems and are generally used in commercial and industrial applications.
2. High efficiency: They can convert the DC power generated by photovoltaic panels into high-quality AC power, improving the system's power generation efficiency.
3. High stability: They utilize multi-stage power conversion technology, ensuring stable and reliable output current.
Distributed photovoltaic inverters
Distributed photovoltaic inverters are distributed near photovoltaic panels, with each inverter dedicated to a specific panel, converting the DC power from multiple panels into AC power. Their characteristics are:
1. Suitable for small-power power generation systems, such as homes and rural areas.
2. Easy installation and maintenance: Each inverter is dedicated to a specific photovoltaic panel, making installation and maintenance simple and convenient.
3. High Flexibility: Inverters can be replaced individually without affecting the operation of the entire system.
Micro PV Inverter
Micro PV inverters are a new type of inverter. Similar to distributed inverters, they are distributed near the photovoltaic panels, but each inverter is only used for one or a few photovoltaic panels. Their features are:
1. Suitable for small-power power generation systems, such as those in homes and rural areas, and can also be used for portable photovoltaic systems.
2. High Flexibility: Inverters can be replaced individually without affecting the operation of the entire system.
3. High Efficiency: By combining maximum power point tracking technology with high-efficiency conversion technology, high-efficiency energy conversion is achieved.
