Application value of solar photovoltaic inverter
Generally speaking, there are two options for the power generation of solar photovoltaic inverter products:
1、Three-phase power module with universal voltage inverter products
• Three-phase power modules are usually used to convert the DC power generated by solar panels into three-phase AC power, providing stable power input for subsequent voltage inverter products.
• Universal voltage inverter products are widely used in various industrial occasions with mature technology and wide compatibility. They can convert the input AC power into AC power with adjustable frequency and voltage to meet the needs of different loads.
three-phase power module with general voltage type frequency conversion products. Because of its simple main circuit and strong versatility, it has a broad application prospect.
2. Use solar photovoltaic converter as interface circuit
• The solar photovoltaic converter is located between the solar power generation system and the AC power grid, and is responsible for converting the DC power generated by the solar panel into AC power suitable for grid access. Depending on the type of converter, it can be voltage type or current type.
• As a bridge connecting the solar power generation system and the power grid, the interface circuit needs to have good stability and reliability to ensure the safe transmission and effective use of electric energy.
Use the solar PV converter connected between the solar power generation and the AC power grid as the interface circuit is expected to continue to reduce its cost. In the past, most of these interface circuits used voltage type converters, and also current type converters.
