What is an inverter?
An inverter, also known as an inverter, plays a crucial role in photovoltaic systems and other applications that need to convert direct current (DC) to alternating current (AC). In this blog post we will take a look at how inverters work, the different types of inverters and what they do.
1.How does an inverter work?
An inverter is basically the heart of a solar power system. Its main task is to convert the direct current generated by the solar cells into the normal household alternating current. This process makes it possible to feed the solar power generated directly into the power grid or to use it for personal consumption in the household.
2. Different types of inverters:
There are different types of inverters, each of which is suitable for specific photovoltaic systems:
String inverters: These are particularly suitable for small to medium-sized photovoltaic systems and work with several solar modules connected in series.
Central inverter: Central inverters are used in larger systems. Although they are efficient, they require a uniform orientation of the solar modules.
Micro inverter: Each solar module is equipped with its own micro inverter. This enables better performance optimization and makes the system insensitive to partial failures.
Grid-connected inverters: They allow the solar power generated to be fed into the public power grid.
3. Tasks and functions of an inverter:
An inverter takes on several important tasks:
Convert direct current to alternating current: The basic purpose is to convert the direct current generated by the solar panels into the alternating current required for household use.
Performance optimization: Advanced inverters have performance optimization features to maximize the overall yield of the solar system.
Monitoring and diagnostics: The inverter constantly monitors the performance of the solar system and provides diagnostic information to quickly identify possible problems.
Feeding into the power grid: Particularly in grid-connected systems, the inverter plays a key role in feeding excess solar power into the public power grid.
Overall, it can be said that inverters are a central component of photovoltaic systems and play a crucial role in converting solar energy into usable electrical energy for daily energy needs.
