How Solar Inverter Works
by UTL Solar India's Best Solar CompanySolar inverters are a crucial component of any solar power
system. They convert the direct current (DC) electricity produced by solar
panels into alternating current (AC) electricity that can be used in homes and
businesses. In this article, we will explain how solar inverters work and the
different types available on the market.
Solar panels generate electricity when photons from the sun
hit the semiconductor material in the panel, causing electrons to flow and
create a current. However, the electricity produced by solar panels is direct
current (DC) and cannot be used directly in most homes and businesses. This is
where the solar inverter comes in.
A solar inverter converts the DC electricity into alternating
current (AC) electricity, which is the type of electricity used in homes and
businesses. The inverter uses a process called inversion to change the DC
electricity into AC electricity. This is done by taking the DC input and
passing it through a set of electronic switches, called transistors, which switch
on and off at a high frequency. This creates a waveform that changes direction,
or inverts, the current, thus converting it from DC to AC.
There are two main types of solar inverters: string inverters
and microinverters.
String inverters are the most common type of solar inverter
and are typically used in larger solar power systems. They are connected to
multiple solar panels and convert the combined DC electricity from all the
panels into AC electricity. String inverters are connected to all the solar panels
in a single string, which is why they are called "string" inverters.
Microinverters, on the other hand, are smaller and are
typically used in smaller solar power systems or in systems where panels are
installed in different orientations or locations. Each solar panel is connected
to its own microinverter, which converts the DC electricity from that panel
into AC electricity. This means that each panel operates independently, and if
one panel has a problem, it won't affect the performance of the other panels.
There are also central inverters, which are large inverters
that are used in large commercial and utility-scale solar power systems.
Central inverters are similar to string inverters, but they are much larger and
can handle more power.
In addition to converting DC to AC, solar inverters also have
other functions such as monitoring the performance of the solar panels,
ensuring that the solar system is working safely and efficiently, and
communicating with the utility grid.
Solar inverters are a
crucial component of any solar power system, and it's important to choose the
right type of inverter for your specific needs. String inverters are best for
larger solar power systems, while microinverters are best for smaller systems
or systems with different panel orientations. Central inverters are best for
large commercial and utility-scale solar power systems.
