Solar panels are steadily gaining popularity among consumers as a viable renewable energy option for powering homes. While most people are familiar with solar panels, which are typically large panels facing the sun during the day, they are only a part of how the solar system as a whole works. The proverbial “heart” of the system is a component called a solar inverter, which is part of the device that converts energy from sunlight into electricity that can be used by homes and appliances.
There are several different types of solar inverters on the market, each with their own advantages and disadvantages. Some inverters can keep power flowing even if one panel is damaged, while different types of inverters can suffer from the same situation. Understanding how each type works will help you make a more informed decision when purchasing or building your own solar system, whether for a home, a greenhouse, or as a backup system during a power outage.
When solar panels are exposed to sunlight, direct current (DC) electricity is generated. A solar inverter is a device that converts direct current into alternating current (AC) energy. Solar panels themselves can only produce DC power, meaning they are not compatible with homes that run solely on AC power, nor with most appliances, so an inverter is required. Moreover, solar panel inverters have a number of features that are useful and convenient for the entire solar power plant.
For example, most modern solar panel inverters can display at least basic system statistics for the day, such as whether the battery is currently charging and how much energy the solar panels have produced. Typically this functionality is basic, but more advanced features such as monitoring power generation over time can be provided in a companion mobile app. However, whether your solar installation is controlled by a mobile app or an inverter, the inverter is still an important part of the system because without it, you won’t be able to use sunlight to power your home and appliances.
There are different types of solar inverters, each designed for different applications and use cases. The most common type of solar panel inverter is the string inverter, also known as a core inverter. The name comes from the design, which is a series of interconnected panels “connected” by wires. This type of inverter works best in an unshaded installation; This is usually the cheapest option and is relatively easy to maintain; The biggest disadvantage of this type of inverter is that it requires maximum exposure to sunlight, plus if one of the panels gets damaged, it will affect the overall power output of the system.
If this is an issue, you may want to consider using a microinverter – this is a compact inverter that is installed on each individual solar panel, allowing them to operate at maximum efficiency independently of the other panels. What’s the status? This also makes it easier to determine which panel is causing the problem. However, microinverters tend to be more expensive than string inverters.
However, homeowners may prefer a hybrid solar inverter, which combines the functionality of a solar inverter and a battery inverter in one unit, providing uninterrupted power as the battery will act as a backup power source in the event of a power outage. The remaining energy stored in the battery inverter can also be sent back to the grid for clean energy, saving money on your energy bills.
When deciding which one to buy, you have to consider more than just the type of solar inverter. First, check the warranty. Since the cost of solar panel systems and their installation can be quite expensive, a warranty can give you peace of mind in the event of potential failures in the future. Solar panel inverters usually come with a separate warranty, which can range from 5 to 25 years, depending on the company and product. Be sure to read the fine print carefully to understand what the warranty covers.
You should also check the peak and weighted efficiency of your solar inverter. Peak efficiency represents the maximum power of the inverter, measured by the exact input power. You must understand that it does not always meet this requirement. This is why a weighted efficiency rating is critical, as it provides a more realistic reading since it includes variables that can affect the DC input level. These two numbers should help you determine if a solar inverter meets your home’s needs.
The last factor to consider is the operating temperature of the solar inverter; It is best to select the product with the highest operating temperature to ensure it operates at or near maximum performance. If the solar inverter you choose cannot withstand extreme climate temperatures, you may experience poor performance during certain times of the year.
