Module inverter
A module inverter is an electronic device that is specifically designed for use in solar systems. In contrast to central inverters, which convert the entire direct current of a solar system into alternating current, each module inverter is assigned to a single solar module or a small group of modules.
How it works:
- Individual performance optimization: Each module inverter continuously monitors the performance of the solar module assigned to it and adjusts its output voltage so that the module reaches its maximum power point (MPP).
- Higher energy yield: This individual optimization increases the overall performance of the photovoltaic system, especially under conditions such as partial shading or different module temperatures.
- Reduction of losses: Since the energy does not have to be transmitted over long cables, the transmission losses.
- Flexibility: Module inverters enable modular system design and make it easier to expand existing systems.
Advantages:
- Increased yield: More electricity is generated through individual performance optimization.
- Greater reliability: A failure of a module inverter only affects the performance of the associated module, not the entire system.
- Flexibility in system design: Module inverters enable adaptation to complex roof geometries and different module types.
- Reduction of shadow effects: Partial shading of individual modules has less impact on the overall yield of the system.
Applications:
- Large photovoltaic systems: Module inverters are often used in large solar parks to optimize the performance of the individual modules.
- Complex roof landscapes: On roofs with different orientations and inclinations, module inverters can maximize the performance of the system.
- Integrated photovoltaics: In building-integrated photovoltaic systems (BIPV), module inverters enable flexible system design.
Conclusion:
Module inverters are an innovative technology that significantly increases the efficiency of photovoltaic systems. Through their individual performance optimization, they help to reduce the costs of generating electricity from solar energy and promote the use of renewable energies.
