A grid-tied solar power system is designed to help your home produce its own energy without running out. Essentially, your home produces its own energy without using local power. Any extra energy not being used is sent into the local power grid. When you need more power, you can use the local power grid. This is what differs it from an off-grid inverter, which completely separates you from the local power grid. Now that you know the basics, you might be wondering how it actually works. Here is some more information on how a Fronius grid-tie solar inverter works.
Collecting the Energy
When you install a solar power system for your home, the energy will be collected with the use of solar panels. Usually, these panels will be placed on the roof of the home and will collect energy from the sun when it beams down on the roof. The only time that the panels will collect energy for your system is when the sun is sending energy to it. This means that you won’t be collecting any energy when it’s too cloudy outside or at night. When the sun produces energy for your panels, it will be collected as direct current (DC) power. However, your home uses alternating current (AC) power for all of your electrical devices. That makes the inverter a key part of your system.
Converting the Power
When you install an inverter in your home, the purpose is to convert direct current power into alternating current power. This is changing the energy that you receive through your solar panels into power that you can use within your home. The inverter will automatically convert the power without you having to do anything. Without an inverter, you’re unable to make this conversion and can’t use the power that you’ve collected from the sun. While on-grid and off-grid inverters convert the power the same way, it’s what they do after that differs them.
Storing the Power
An off-grid inverter system collects the power and stores anything you don’t use in batteries. An on-grid system sends any of your extra power back into the local power grid. This power will then be distributed throughout your neighborhood, providing quality power for your friends and neighbors. The sending of this power back into the public system is known as net metering. This means that you’re given credit from the power company for what you send back into the public system. When you need to use public power again, this credit will be used, saving you money on your power bill.
If you’re looking to save money on your energy bills, you can install a solar power system. This will allow you to either store your own power or provide your extra power to the local power grid. These are the steps you should know when installing a fronius grid tie solar inverter.
