Almost everyone is aware that solar panels gather sunlight. But, many people wonder how it converts sunlight into electricity. Solar inverters convert the electricity accumulated by the solar panel, and it transforms into a usable form that can be utilized by appliances. 

Investing in solar panels is a long-term investment and their usage is relatively high. Nonetheless, it is vital to know how solar inverter works to fully be familiar with them.

What Is A Solar Inverter?

The primary function of a solar inverter is to accept the direct current power input and turn it into an alternating current. Solar inverters are a primary connection between the electrical distribution and the panels. 

Modern solar inverters have switches that can easily isolate or connect the solar power system from the grid. 

How Does A Solar Inverter Work? 

This part will explain the operating principle and the working process of solar inverters.

The Working Principle Of Solar Inverters

The working principle of a solar inverter is that the inverter takes in the variable DC or direct current output from the solar panels. After that, it converts into an AC of 120V or 240V. 

The appliances do not run on direct current; they run on alternating current, which is why the solar inverter converts DC into consumable energy. 

The Process Of How Solar Inverters Work

The photovoltaic cell is made up of semiconductor layers and the sun’s rays fall on the photovoltaic cells. These layers absorb the light and then transfer it to the cells where solar electrons generate a direct current that is either stored in a battery for energy storage or it is sent to the inverter. The inverters have transistors that quickly turn on or off and convert the current.

Types Of Solar Inverters 

There are three types of solar inverters. Each of these microinverters has similar functions, but their difference does not lie in what they do; in fact, it lies in how they do it. 

String Inverters

A string inverter or a central inverter. It accepts the DC from different solar panels and converts them into AC. It works best when there is a need to convert energy into a large amount. 

Pros

  • String inverters are less expensive
  • Easy to install
  • They have fewer components 
  • Easy to maintain and troubleshoot

Cons

  • It has limited maximum power generation

Microinverters

A microinverter is present at each solar panel. It can easily convert the energy before it sends it to the house to meet with other inverters’ power.

Pros

  • Microinverters can instantly change DC into AC
  • Provides maximum power to the system
  • Do not require mechanical cooling
  • Provides optimal energy efficiency
  • Lasts longer

Cons

  • Microinverters can be expensive

Battery Inverters

If anyone wants to keep the battery separate from the solar system and run via a different inverter, then a battery inverter is the best option. It converts the battery power and feeds it into the switchboard. 

Pros

  • Battery inverters are economical
  • Produces a large amount of current

Cons

  • Battery inverters require regular water toppings
  • They require maintenance

What Makes A Good Solar Inverter? 

Apart from knowing solar inverters work, it is equally important to know what makes a good solar inverter. 

Suitable Size

To ensure that the solar inverter is working perfectly fine, it is essential that it can handle the maximum power. It depends on the size; when installing a 5-kilowatt solar energy system, the solar inverter must be 5,000W.

CE Certification

Safety is one thing that you must not compromise. So, you must ensure that the solar inverter is certified safe and should come with a CE certificate from an accredited laboratory. This certificate is a declaration by the manufacturer stating that the inverter has met all the requirements of the EC directives. 

Weatherproof Protection

The solar inverter and mostly the grid-connected ones should be weatherproof. It is so because they can be exposed to the areas that might have exposure to the rain. With weatherproof protection, solar inverters can be protected from possible damage. 

Warranty

A solar inverter has a lifespan of ten to twenty years. And any good quality inverter should last at least ten years. So, any reliable manufacturer will provide a warranty of at least ten years, and they can even offer warranty extensions too.
