String inverters are a popular choice for solar energy systems and are known for their reliability and efficiency. In this blog, we will take a closer look at what string inverters are, how they work, and the advantages and disadvantages of using them in a solar energy system.
What is a String Inverter?
An inverter is an indispensable part of solar energy systems. It changes direct current (DC) electricity created by a solar array into alternating current (AC) electricity, which most homes and businesses use. Additionally, the inverter tracks the system’s performance, optimizes the output, and guarantees the system generates energy at the highest efficiency. String inverters are generally the most economical choice for residential and smaller commercial solar systems, and they are a necessary part of any solar energy system.
How Does a String Inverter Work?
A string inverter takes the DC energy from solar panels and converts it into AC energy through diodes and transistors. It also includes Maximum Power Point Tracking (MPPT) to maximize energy output and safety features to guard against power surges and other damages.
Advantages and Disadvantages of These Inverters
Advantages:
String inverters are simple to install and require very minimal wiring. They are generally the most cost-effective option for solar installations. On top of that, string inverters offer high efficiency ratings, allowing for more energy production from fewer panels. One unique thing about these types of inverters can be easily integrated with existing power systems and offer a variety of connection options.
Disadvantages:
If one panel in a string of panels is not functioning properly, it can affect the output of the entire string. String inverters only provide overall system performance data, and it can’t monitor the performance of individual panels. Identifying and fixing issues with individual panels can be difficult because the inverter is connected to multiple panels.
Are String Inverters Worth It?
String inverters are a popular and cost-effective option for solar energy systems. They are known for their reliability and can handle a large number of solar panels. While they have some disadvantages, they are still a good option for those who want to install a larger solar energy system.
