What are the advantages of micro inverters over conventional inverters?

In the past two years, solar micro inverters have emerged in the field of photovoltaic, in Europe, because of the high cost of electricity, so that more and more families choose the Balcony Power Plant with microinverters.What are the advantages of micro inverters over conventional inverters?

Independent control and optimisation

Independent MPPT control: Micro inverters are capable of independent maximum power point tracking (MPPT) for each solar panel, which means that they can be optimised according to the actual situation of each PV panel, thus improving the overall system power generation efficiency. In contrast, conventional inverters can usually only perform uniform MPPT control for the entire PV array, and are unable to take into account the optimal operating conditions of each PV panel.

Increase power generation

Reducing the impact of shadows: In the case of shadow blockage in the PV array, the microinverter can minimise the impact of shadows on the whole system. Since each PV panel is equipped with a separate inverter, shadows on one PV panel do not affect the performance of the others. Conventional inverters, on the other hand, may reduce overall power generation due to shadows across the entire array.

Easy monitoring and maintenance

Real-time monitoring: Microinverters are usually equipped with a monitoring function that can monitor the performance parameters of each PV panel in real time, such as power generation, voltage, current, etc. This enables the user to know more accurately the performance of the PV system. Traditional inverters may not be able to provide such detailed monitoring information.
Reduced maintenance costs: Since each PV panel is equipped with an individual microinverter, when an inverter fails, it can simply be replaced without the need for large-scale repairs to the entire system. This greatly reduces the maintenance cost and difficulty of the system.

Safety and Reliability

Low-voltage design: Microinverters usually operate at a voltage of only a few tens of volts, whereas traditional inverters operate at up to several hundred volts, which greatly reduces safety hazards.
Long design life: Microinverters are usually designed for a long life (e.g. 25 years), which means it can work stably for a long time without frequent replacement.

Flexible installation and configuration

Simple installation: Microinverters can be mounted directly on the back of the solar panels or on a rack without the need for additional facilities such as a power distribution room. Even balconies with little space can be easily installed.
Flexible Configuration: Microinverters can be configured very flexibly, allowing the installation of different numbers and powers of PV panels according to the user’s actual needs and economic conditions. This flexibility makes microinverters very popular in the home market and small commercial market.

Summary

In summary, compared with traditional inverters, microinverters show significant advantages in independent control and optimisation, improved power generation, convenient monitoring and maintenance, safety and reliability, flexible installation and configuration, as well as intelligent and remote management. These advantages make microinverters more and more widely used in solar PV systems.
