With a shift toward renewable energy, governments have introduced numerous initiatives encouraging homes and businesses to install solar panel systems. By generating clean electricity on-site, these systems reduce dependence on traditional fossil fuels, contributing to a more sustainable and environmentally friendly energy landscape.
This blog post dives into the importance of microinverters, helping you understand how they work and why they form an essential part of effective solar panel design.
What Are Microinverters and How Do They Work?
Microinverters convert the direct current (DC) collected from each solar panel and transform it into alternating current (AC), a type of electricity that can be used to power buildings and appliances.
Microinverters are classed as module-level power electronics (MLPE) because microinverters operate on each panel independently of the other inverters in the system. The fact that microinverters function independently brings several benefits. For example, if something is wrong with one microinverter, only the panel attached to it will shut down instead of the entire system.
How Do They Differ from String Inverters?
Microinverters and string inverters are two solar inverters which differ in terms of wiring. String inverters connect several solar panels in a series, while microinverters are connected to individual panels within a system.
Because string inverters connect to multiple panels, you may only need one or two for an entire solar panel system in comparison with microinverters, which require more, making them cheaper to install and maintain.
However, the simplified wiring of string inverters has several disadvantages. Because string inverters are not connected individually, any issue with individual solar panels affects the entire circuit and not solely that panel's output. Additionally, Additionally, upgrading your solar panel system by adding extra panels is more complicated and costly when using string inverters.
The Advantages of Microinverters
Microinverters create flexible solutions for many solar installations. Here’s a quick rundown of the main advantages of using microinverters for solar panel systems.
Monitoring Capabilities: Users can track the performance of each solar panel, allowing for the quick identification of issues with specific panels and facilitating faster diagnosis and repair.
Enhanced Energy Efficiency: Microinverters optimise the output of each panel individually, ensuring that even if some panels are underperforming due to factors like shade or dust, the overall system efficiency is maximised.
Ease of Expansion: Each microinverter supports up to four panels, making it easy to upgrade your solar panel system by simply adding more panels without complex modifications.
Improved Safety: By converting DC to AC at the panel level, the microinverter reduces the amount of high-voltage DC transported through the system, lowering the risk of electrical fires and high-voltage arcs.
Increased Longevity: Microinverters reduce the impact of component failures by working independently, which often results in extended warranty periods compared to other inverters.
