Installing a solar power system can be an overwhelming process. There are multiple products available on the market, and it can be tough for people to figure out which pieces they need. Two components that are commonly involved in solar setups are converters and inverters. Here is a look at each component, to help people figure out which device is best for their situation.
Inverters are able to switch the power from DC to AC. Inverters allow for the energy generated by solar panels to be put to use. Primarily, there are three inverters used in solar power systems. String inverters are used for commercial and home solar power systems. String inverters are efficient and inexpensive compared to other types of inverters. However, they do not have panel level monitoring and their high voltage makes them dangerous. Microinverters are small inverters that are located near the solar panel. They convert the DC electricity. Microinverters also allow systems to keep working, even if there is a problem with one of the panels. Microinverters are expensive and require lots of maintenance. Central inverters are designed for larger arrays, functioning like a group of string inverters. Central inverters are easy to install and have a low capital price per watt. Central inverters are large, which means that the whole system may become damaged if one part malfunctions.
Converters are electrical devices that adjust the DC voltage output either up or down depending on the input level. Converters are able to maximize the energy being harvested for the system while also helping regulate the amount of energy circulating through the system. Everything in the system receives a regular current. The pulse width modulation converter connects a solar array to a battery. The Maximum Power Point Tracking Converter can adjust the energy intake and increase the overall output efficiency for the system.
Which One Is Best?
Before a person decides on which device to purchase, they should look at the type of solar setup that they want to run. People who use a battery bank should consider purchasing a Maximum PowerPoint Tracking Converter. People who plan to expand their array in the future may seek to go for a microinverter. People should also think about how many watts their solar array can generate, as well as the number of watts that the household uses.
