Microinverters are used to maximize the efficiency and performance of solar energy systems. They are installed on each individual solar panel, allowing the conversion of direct current (DC) to alternating current (AC) at the panel level. This approach ensures that each panel operates independently, reducing the impact of shading, dirt or other obstructions on overall system performance.
By optimizing the efficiency of each panel, microinverters can improve power production, improve system reliability, and provide detailed monitoring of each panel’s performance.
The use of microinverters offers several advantages over traditional central or string inverters. Unlike central inverters, which convert the combined power of all connected panels into a single unit, microinverters convert direct current to alternating current for each panel.
This decentralized conversion process allows each panel to perform optimally regardless of the performance of other panels in the system. Microinverters also provide real-time monitoring of each panel, making it easier to detect and resolve problems quickly and efficiently.
The main difference between an inverter and a microinverter is their operational design. Traditional inverters, also called central or string inverters, manage the conversion of DC electricity from multiple solar panels into AC energy in a single unit. This can lead to inefficiencies if one of the panels underperforms.
Microinverters, on the other hand, are installed on each panel and perform the conversion individually. This configuration allows each panel to operate at its maximum efficiency, which can result in higher overall energy production and better performance tracking.
Microinverters should be placed on or near each solar panel, usually mounted on the rack system or on the back of the panel. The location should ensure secure mounting and allow adequate ventilation to prevent overheating.
It is important to follow the manufacturer’s recommendations for assembly and installation to optimize the performance of each microinverter and to facilitate maintenance and troubleshooting.
Installing two inverters can be advantageous for several reasons. In some systems, multiple inverters are used to manage different parts of the solar panel or to balance the load if the total power exceeds the capacity of a single inverter. Additionally, having two inverters can provide redundancy; If one inverter fails, the other can continue to operate, minimizing system downtime.
In some cases, combining different types of inverters, such as central inverters with microinverters, can optimize the performance of different sections of the solar power system.
