An inverter is a device that converts direct current (DC) electricity into alternating current (AC) electricity. This is important because most household appliances, like refrigerators and televisions, run on AC power. Inverters are commonly used in solar energy systems, where solar panels generate DC electricity that needs to be converted for home use. Inverters come in various sizes and types, depending on their application. For example, a small inverter might be used to power a laptop, while larger ones can support an entire home. They play a crucial role in renewable energy systems, helping to make clean energy accessible and usable for everyday life.
