Micro inverters - maximum power and flexibility for your solar system

Micro inverters offer an advanced solution to optimize the performance of solar systems. They convert the direct current of each individual module into alternating current, resulting in a higher overall output. Especially in cases of shading or different module orientations, micro-inverters ensure that each module operates independently, maximizing efficiency. They also offer greater system reliability, as an inverter failure only affects the affected module, not the entire system.

Micro inverters offer an efficient, flexible and reliable solution for any solar installation and maximize its energy yield.

What are micro inverters?

Micro-inverters are specialized devices that convert the direct current generated by each individual solar module into alternating current. Unlike traditional central inverters, which control multiple modules, each micro-inverter works independently, optimizing the output of each module individually. This technology is particularly suitable for solar installations where there are different orientations or shading, as each module can operate independently to achieve maximum efficiency.

How do micro inverters work?

Micro inverters are installed directly on the individual solar modules. They immediately convert the direct current generated by the module into alternating current, which is then fed into the electricity grid. As each micro inverter works separately, the overall output of the solar system is optimized, even if some modules cast shadows or have different orientations.

The advantages of micro inverters

Maximum efficiency: Micro inverters ensure that each module works independently, maximizing energy yield even in different conditions. Even with partially shaded or dirty modules, energy production is optimized as each module is individually monitored and adjusted.

Greater reliability: If a micro inverter fails, only the affected module is affected, while the rest of the system continues to function. This increases operational reliability and reduces downtime compared to centralized systems.

Easy monitoring: Micro-inverters often provide a user-friendly platform for monitoring each individual module, making maintenance and troubleshooting easier. Users can monitor the performance of each module in real time and respond immediately if problems occur.

Scalability: Micro-inverters are ideal for small to medium sized solar installations and offer the ability to expand the system at a later date without the need for reconfiguration.

Disadvantages of micro inverters

Higher initial costs: Micro-inverters can be more expensive to install than centralized systems as a separate device is required for each module. However, this higher initial investment can be offset by the long-term savings in maintenance and downtime.

More complex installation: The installation of micro inverters requires more effort and may be a little more demanding. Professional installation is therefore recommended to ensure the efficiency of the system.

Benefits for installers
Flexibility: Micro inverters are ideal for different roof types and difficult installation conditions.
Faster fault diagnosis: Thanks to individual monitoring, installers can quickly identify defective modules.

Service life and warranty

Longevity: Micro-inverters are characterized by a longer service life compared to traditional central inverters, as they are less susceptible to overheating and other problems. Many micro inverters have a guaranteed lifespan of 20 to 25 years, making them a long-term investment.
Warranty: The warranty period for micro inverters varies depending on the manufacturer, but is often between 10 and 25 years, which guarantees high reliability and low maintenance costs over the years.

Increased efficiency with partial shading

Optimization in the event of shading: One of the biggest advantages of micro inverters is their ability to ensure high efficiency even in the event of partial shading or non-optimal roof orientation. Whereas with central inverters, the performance of the entire system is impaired if a single module is shaded, micro inverters work individually so that the remaining modules can continue to deliver their full performance.

Learn more about 1-phase inverters and 3-phase inverters

Single-phase inverters are ideal for smaller residential solar systems as they offer a cost-effective solution for converting direct current to alternating current and are suitable for moderate energy requirements. They are easy to install and particularly suitable for simple applications. 3-phase inverters, on the other hand, are designed for larger solar installations and commercial applications. They ensure a more even distribution of power and are the preferred choice for systems with high energy requirements, as they work more efficiently and offer a higher output.
