Micro-Inverter
A micro-inverter, also known as a module inverter, is an electronic device that is connected directly to a single solar module. Unlike central inverters, which convert the entire direct current of a photovoltaic system into alternating current, each micro-inverter converts the current from a single module.
How it Works:
- Direct Current to Alternating Current: Solar modules produce direct current. The micro-inverter's role is to convert this direct current into alternating current suitable for household use.
- Performance Optimization: Each micro-inverter individually optimizes the performance of its assigned solar module. This ensures that each module delivers its maximum yield, even if other modules are affected by shading or dirt.
- Modular Structure: The modular structure of a photovoltaic system with micro-inverters allows for flexible installation and expansion.
Advantages of Micro-Inverters:
- Higher Overall Yield: Individual optimization of each module increases the overall yield of the photovoltaic system.
- Yield Stability: Shading or dirt on individual modules has less impact on the overall yield of the system compared to central inverters.
- Safety: Since each micro-inverter feeds only a small circuit, the risk of fires is reduced.
- Monitoring: Modern micro-inverters enable detailed monitoring of the performance of each individual module.
- Flexibility: The modular structure facilitates the installation and maintenance of the photovoltaic system.
Applications:
Micro-inverters are particularly suitable for:
- Complex Roof Shapes: For roofs with different orientations or shading, micro-inverters can optimize yield.
- Partially Shaded Systems: Even under significant partial shading, each module can contribute to the overall output.
- Extensions of Existing Systems: Micro-inverters allow for easy expansion of existing photovoltaic systems.
Conclusion:
Micro-inverters represent an innovative solution for optimizing photovoltaic systems. With their numerous advantages, they are particularly suitable for demanding installations and contribute to increasing the efficiency and profitability of solar systems.
