How Solar Inverter Works & It’s Applications

Solar Inverter is the ultimate device that can alter the direct current output of the heat consumption by solar panels into the alternate current. The electric elements in the solar inverter circuit are responsible for the energy and current conversion.

How Does A Solar Inverter Work?
Where inverters are used, the major need is for solar energy getting used as an all-time power source from the battery inverter system. It requires MOSFET Driver, PWM inverter IC, Bridge-MOSFETs Drive, Solar Panels, Steps Up Transformers and batteries to function properly. Photovoltaic cells help in the conversion of solar energy into electrical energy. During the day-time, the energy converted is stored for later use so that the homes requiring electricity can use this solar energy with the help of the inverter.

The photovoltaic solar panel’s output of direct current is converted into an alternate current that goes straight to the connected commercial grid. Using the PWM inverter IC and MOSFET, the solar energy stored in the photovoltaic cells gets altered into the alternate current. This conversion allows the electricity to power the systems. Voltage amplification, performance to the circuit and the flow function are controlled by the solar inverter as it keeps the operating current flow parallel.

Since solar energy proved to be a great source of fuel and energy for machines such as cars, home appliances etc, solar inverters have varied from the basic systems to advanced technology. Here are a few of its applications:

1. Micro Inverters
As is it named, microinverters tend to be small and portable which provide equally as much output and performance as other inverters. They also have all the central inverter features. These inverters are not only used on a wide scale commercially but also on a residential ground as they are capable of monitoring each panel’s performance. These are very easy to install but are costly as compared to other types of inverters as they can be sold through manufacturers like AC Modules.

2. Battery Based Inverters
These types of inverters are highly essential as they are bi-directional in nature. The battery charger and the inverter are both capable of providing alternate current power to heavy loads during power cuts. Depending on their design and UL rating, these inverters can be off-grid, grid-tied or grid-interactive. The major advantage of these inverters is that they can provide continuous current despite the grid condition. Keeping the batteries charged, battery-based inverters easily manage the energy supply between the grid and the array.

3. String Inverters
In this type of solar inverter, each panel gets installed on a string in a row. Likely, all the strings are attached to one main string inverter. Through the solar panels, each string carries the direct current to the string inverter and changes it into an alternate currency that can be later used as electricity. Since this type is quite primeval, it is easy to install as the panels are faced in one direction on a plane surface with no shading issues at all. It is not as flexible as the battery-based inverters because the entire string panel struggles with performance if one of the panels is shaded. But string inverters are cheaper than the micro-inverters.

4. Central Inverters
The difference between string inverters and central inverters is that of the size. These two are quite similar but central inverters tend to be larger in size and produce much more energy as well. In this type, the strings are all in a combiner box tied and attached together. This box carries direct current straight to the central inverter where is it is converted to alternate current. There are not many components in the systems but a common combiner box and a pad is a must.
