A solar inverter is a main and important part of a solar system. This is known as the heart of the solar system. A solar inverter converts DC (low voltage variable direct current) into AC Power (Alternative current) for electricity supply to the residential system. In our residential and commercial electrical system we are using AC power. Solar inverters get DC power from the Photovoltaic solar system. And then send it to the electricity system by converting it AC power. If we are storing electricity in the battery for a long time usage than solar inverters are very useful. The solar inverter connects with the battery system. This protects your system by an electronics shutdown named anti-islanding Protection.
Solar Inverter Types:
Solar inverters are available in different types based on their functionality. Every type has its own functionality and specification. Solar inverters are available in three major types;
Grid-tie Power inverters:
It is clear from the name of this inverter that it will connect to the electricity grid. If you want to use the solar system with the grid electricity then you can use a grid-tie power inverter for this purpose. This inverter will help you to maintain the power frequency on both sides. In your solar system, as well as grid electricity, provide.
You should have an agreement on this type of solar system. When there is a low voltage frequency on the grid side, electricity providers can deduct electricity from your side’s power system. By this, your electricity bill will be adjusted with plus and minus. You can sell the extra solar electricity under some agreements. If you are producing electricity more than your consumption you can sell this electricity to the grid. When you are using a grid-tied solar inverter you do not need any battery. And when there is a shortfall on the grid side, your inverter will be shut down automatically because of anti-islanding protection.
How to use the solar inverter in grid power outages?
You should use battery backup inverter When you are suing grid-tied solar inverter at that place where are more chances of power outages. By this, you can use AC power in the grid power shortfall. These inverters will charge the battery in priority and then send extra power to the grid. These are more expensive as compared to Grid-tie inverter. But if you want a battery backup at the power fall places, then nothing is batter then battery backup inverter.
When you are using the off-grid solar system then you should use a standalone inverter. You are not connected with grid electricity. As you are using your own produced electricity, so you should have a battery backup system. Standalone is the best option for this type of solar system.
These solar inverters have the ability to keep the electricity backup as well as AC power supply. For this type of system, you don’t need any type of anti-islanding system because you are not connected with the grid system and do not provide the electricity. These inverters are very effective for the commercial sector.
The advanced shape of solar inverters is Microinverter. They are very small, reliable and easy to install and maintain. Micro-Inverters are as small as a little book. They are more efficient because they are used with a single solar panel.
When you want to add more solar panels, you can install a new microinverter on the back of the solar panel. They are more efficient than any other solar inverter but are costly also.
You can monitor every solar panel separately and can find the problem and resolve it easily. You can analyze the efficiency and working of solar panels. Up-gradation and degradation can never harm the whole system. If any inverter of them is not working properly we can change it easily. Single inverter failure can never affect the whole system as compared to any other system in which you need to check the inverters’ specifications.
Last words about solar inverter:
Hopefully, now you know about the solar inverters and its types. Choose a solar inverter according to your need and your solar system. After selecting a solar inverter you should analyze its specification and cost of different brands. You can buy solar inverters from your local market as well as from your online market. Solar inverters are available in different price ranges. Choose a solar inverter under your estimated price range. A solar system will provide you a low cost, environment-friendly and longtime electricity power.
