What Are Microinverters and How Do They Work?
You may wonder how microinverters work and their role in solar energy systems. To put it simply, microinverters convert the direct current (DC) power generated by individual solar panels into alternating current (AC) power. This AC power is then sent to your home or business for use. These small devices are found right on the back of each solar panel in your solar array.
The great thing about microinverters is their modular nature. They optimize the performance of each panel separately. If one panel is in shade or underperforming, it won’t affect the rest of the system. This also means that you can easily expand your solar array by adding more panels, which is a huge plus for those looking to grow their renewable energy capabilities.
In a nutshell, microinverters take the DC power produced by each solar panel and turn it into usable AC power for your home or business. Their individual panel-level optimization ensures your solar system works at its best, giving you a reliable and efficient renewable energy source. No wonder microinverters have become a popular choice in solar technology!
