A solar power system is made up of different components, which include solar panels, charge controllers, and, importantly, inverters. Then, what is a solar power inverter, and how does a solar power inverter work?
In short, the solar power inverter converts panel-generated DC energy into AC power for direct use or being fed into the grid. But there is more to explore. For instance, they can monitor and detect faults in real time for efficiency and system safety.
Remember, solar systems cannot communicate with AC systems without inverters. With their significance, this article will focus on inverters, giving a comprehensive guide for you to understand what an inverter is, how it works, and its different types.
Solar Power Inverter Explained
1.What Is A Solar Power Inverter?
A solar power inverter is a key component in a PV system to achieve power conversion from DC power to AC power. With a sophisticated design, it can have a switch that enables the connection between the solar power system and the grid. Therefore, the generated AC power can be either directly used or distributed into the grid.
A leading inverter can ensure maximized energy production by producing a pure sine wave output. It also helps monitor the power output of the system and detect any possible issues before it is too late.
2.How Does A Solar Power Inverter Work?
Then, how does a solar power inverter work? The inverter works by using switching components, including insulated-gate bipolar transistors or metal-oxide-semiconductor field-effect transistors, to change the DC power for a pulsed waveform.
The pulsed DC is changed into a smooth AC sine wave through filters. The inverter synchronizes the output with the grid’s voltage and frequency or off-grid load demands. Notably, it also manages voltage fluctuations to protect appliances and avoid overloads.
3.Solar Power Inverter Types
There are different types of solar power inverters, and some of the common types are:
- Hybrid inverters enable energy storage in a battery energy storage system. Excessive power will be transferred to the power grid when it is not instantly used and the battery is in full charge.
- Micro invertersare installed on each panel for granular performance tracking. They enable quick module problem detection and achieve high efficiency. The con side is their relatively higher price.
- Grid-tied inverterssynchronize with the electrical grid and don’t store energy. Instead, they feed surplus power directly back into the grid.
- Off-grid invertersoperate independently of the grid. They require battery management and may include battery charging features for a self-sufficient system.
FAQs about Different Solar Inverters and Solar Systems
1.What‘s the Difference Between On-Grid, Off-Grid, and Hybrid Solar Systems?
On-grid systems connect to the utility grid and rely on it when the sun isn’t shining. When solar production exceeds consumption, surplus energy feeds into the grid. Conversely, off-grid systems function without utilities. They require battery storage to handle the night or cloudy days. Hybrid systems are a more flexible solution. These systems work with the grid and backup batteries, which means they can both utilize grid power and stored solar energy.
2.Which Type of Inverter Is Better?
It depends on your system’s needs. For instance, string inverters are cost-effective as they handle panels connected in series. However, their output performance can be compromised if there are solar panels are shaded. Meanwhile, microinverters allow independent optimization, as they each handle only one panel. The shading of one panel doesn’t affect others, but they can be more expensive.
Different application scenarios are recommended with different inverters. As a leading and experienced solar product manufacturer, Sunway can offer tailored advice for your projects!
3.How Long Does a Solar Inverter Last?
Solar inverters may last 10-25 years, depending on their types and designs. Their service life can be shortened by many factors, like high temperatures, humidity, and dust. Therefore, it is important to install them in a well-ventilated and shaded space. Furthermore, regular upkeep and firmware updates can also help.
