Before delving into the different types of QMA inverters, it is important to understand what an inverter is. An inverter is an electrical device that converts direct current (DC) into alternating current (AC). The QMA inverter is a type of grid-tied inverter. It is an intelligent power conversion device that performs maximum power point tracking (MPPT). The QMA inverter works by extracting the maximum possible power from solar panels and transferring it to the grid or for local use.
There are three main types of QMA inverters, as discussed below:
String Inverters
This type of inverter is the most popular. It works by connecting a string of solar panels to one inverter. The QMA string inverter converts the DC power generated by the panels into AC power. The conversion process is done as a unit, meaning the solar panels operate together as a team. A single inverter can be connected to multiple strings. Each string will have its own circuit and will be connected to the same inverter.
QMA string inverters are reliable and cost-effective. However, they have one major disadvantage: if one panel in the string is affected, the rest will also be affected. This is known as the ''panel mismatch effect.'' The other disadvantage is that all the panels must face the same direction. They can only be installed in areas with good sunlight.
Central Inverters
Large-scale solar power systems commonly use central inverters. These systems are installed in places like solar farms. The central inverter is installed in one location and connected to multiple strings of solar panels. It is powerful enough to handle the output of many panels.
One of the benefits of central inverters is that they provide a lot of power. They are also very efficient. However, like string inverters, central inverters have a disadvantage. If one panel is affected, the rest will also be affected.
QMA Microinverters
Microinverters are another type of QMA inverters. They are installed directly on each solar panel instead of on one unit for a string of panels. Microinverters work on each panel separately. This means if one panel is affected, it will not affect the others. Microinverters are good for installations where the panels may be shaded at different times or face different directions.
