What is the difference between a string inverter and a microinverter?





String inverters and microinverters are two different types of solar inverters that are used to convert DC electricity from solar panels into AC electricity that can be used in homes and businesses.


A string inverter, also known as a central inverter, is a single inverter that is connected to multiple solar panels, or "strings" of panels. The DC electricity from all of the panels is combined and then converted into AC electricity by the string inverter. This type of inverter is typically installed near the electrical panel and is connected to the electrical grid.


A microinverter, on the other hand, is a small, standalone inverter that is installed on each individual solar panel. Each microinverter is responsible for converting the DC electricity from its corresponding panel into AC electricity, and all of the microinverters are connected to the electrical grid.


The main difference between the two is that a string inverter uses a centralized design, while a microinverter uses a distributed design. Microinverters are more flexible and allow for easy expansion of the solar panel system, as panels can be added or removed without affecting the performance of the rest of the system. Microinverters also offer increased system performance and reliability, as each panel operates independently, and if one panel fails, the rest of the system continues to operate normally.


The choice between a string inverter and a microinverter depends on your specific needs and requirements, including your energy consumption patterns, the size of your solar panel system, and the location of your panels. It is advisable to consult with a solar panel professional or a licensed electrician to help you determine the best inverter for your specific needs.
