Micro inverters - maximum power and flexibility for your solar system

Micro inverters convert the direct current of each individual solar module separately into alternating current - for maximum efficiency and optimum energy yield. These decentralized inverter technologies ensure that each module works independently - particularly advantageous in the event of shading, partial soiling or different roof orientations. This significantly increases the overall efficiency of your system.

Enphase offers powerful devices with intuitive monitoring, a long service life and simple integration. Hoymiles scores with compact, efficient systems that can be used flexibly in different solar systems - from small house roofs to commercial PV systems.

Micro inverter systems offer a scalable, safe and future-proof solution to exploit the full potential of any solar installation.

What are micro inverters?

Micro-inverters are specialized devices that convert the direct current of each individual solar module directly into alternating current. Unlike conventional central inverters, they work independently of each other, maximizing the output of each module individually. This technology is particularly beneficial for solar installations with varying orientations or shading, as each module can be optimally utilized to increase overall efficiency.

How do micro inverters work?

Micro-inverters are mounted directly on the solar modules and immediately convert the direct current generated into grid-compatible alternating current. The independent operation of each inverter improves the overall performance of the solar system - even with partial shading or different module positions.

Advantages of micro inverters

Maximum energy efficiency: Micro inverters optimize the output of each solar module individually. Even with partial shading, soiling or different orientations, the energy yield remains high - for maximum solar power production.
Increased reliability: If a micro inverter fails, this only affects the individual module. The rest of the system continues to run smoothly, which minimizes downtimes and increases operational reliability.
Simple and precise monitoring: Micro inverters usually offer integrated monitoring systems that provide real-time data for each module. This makes maintenance and rapid fault detection much easier.
Scalability and flexibility: Ideal for small to medium-sized systems. Systems can be easily expanded without having to convert or reconfigure existing systems.

Disadvantages of micro inverters

Higher acquisition costs: The investment is usually higher than with central inverters, as one inverter is required per module. In the long term, savings on maintenance and downtime can offset these costs.
More complex installation: Installation requires more time and expertise. Professional installation ensures optimum performance and avoids errors.

Advantages for installers

Flexible application options: Micro inverters are particularly suitable for complex roof shapes and demanding installation conditions.
Fast fault diagnosis: Thanks to individual module monitoring, installers can quickly locate and rectify faults, which increases service quality.

Service life and warranty of micro inverters

Longevity: Micro inverters have a longer service life than conventional central inverters. They are less susceptible to overheating and technical failures. Many models offer a guaranteed service life of 20 to 25 years, making them a sustainable and long-term investment.

Warranty: The manufacturer's warranties are usually between 10 and 25 years and underline the high quality and reliability of the devices. This results in low maintenance costs and stable system performance over the entire service life.

Increased efficiency with partial shading

Optimum performance even with shading: Micro inverters ensure that each module works independently even with partial shading or different roof pitches. While central inverters reduce the overall output of the solar system when one module is shaded, micro inverters ensure that the other modules continue to deliver their full output - for maximum energy yield under real conditions.

Where are micro inverters used?

Micro inverters are used wherever maximum flexibility and efficiency are required: in private PV systems with complex roof shapes, shaded or differently aligned modules. They also ensure optimum energy yield and easy expandability in small and medium-sized commercial solar systems. Their modular design makes them perfect for retrofitting and locations with varying solar conditions - for reliable and intelligent use of solar power.

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.
