Grid tie inverter

A grid-tied renewable energy system consists of many different important parts but the most important part by far that is absolutely vital for the system to work properly is the grid tie inverter. Without the grid tie inverter the energy system would not be capable of working properly. If you have an energy system that is grid-tied it simply means that it is plugged into the local power grid. This is where using a grid tie inverter is absolutely necessary. A grid tie inverter will convert DC (direct current) to AC (alternating current) when hooked up to your power supply. This is necessary if you want a very reliable renewable energy system that incorporates solar energy and an alternating current charge as well.
Alternating Current and Why It’s Important
One of the main downfalls to using solar panels is that the sun will not always be out. There will be some days that you may not be able to get enough solar energy because of what its like outside. If you want to be sure you always have a power supply while relying on renewable energy you would want to use a grid tie inverter to get an alternating current.
Basically the alternating current will activate when your solar panels are not able to absorb a sufficient amount of sun light. So the grid tie inverter will use power from the local power grid and in the process it will convert it to an alternating current. The grid tie inverter is a vital component as it is reliable for regulating the power supplied.
The Grid Tie Inverter’s Responsibilities
There are a few things that the grid tie inverter is doing. The main responsibility it has is obviously to convert the power from DC (direct current) to AC (alternating current) but there are still other tasks it must perform to keep everything flowing properly. One process in particular it must complete that is very important is the net metering process.
The method of net metering with a grid-tied renewable energy system will allow you to save quite a bit on electricity. As well, since you are not using batteries within your grid-tied energy system, the maintenance becomes much easier. Along with that, the grid tie inverter will power off automatically if no current is identified. This is purely for safety reasons so there are no electric surges as a result of the inverter still being on.
Of course, you still have the option of setting up your energy system with batteries and the grid tie inverter can work sufficiently with batteries as well. If you choose to set up your grid-tied system with batteries then the inverter will be capable of charging the batteries while working with the local power grid. The grid tie inverters that are used with batteries are often referred to as multifunction inverters but in general they are grid tie inverters as they work with the power grid still, even with batteries in the setup.
There are advantages to each method so you will have to make up your mind as to which advantages are superior. For instance, take a look at the setup you would have if you were using the grid tie inverter with batteries. You will be able to keep your batteries fully charged and if for some unforeseen reason your power goes out then you have a power source to last you until it comes back up. While the inverter is charging your batteries it is still working with the power grid as well.
So, we can definitely conclude that there are many reasons why a grid tie inverter is an important part of any renewable power energy system. The grid tie inverter is a vital part of your energy system no matter how you have it set up and it can be prominent whether you choose to include batteries in the set up or not.
