Solar cells need inverters to convert their DC output to AC. The main reason for this is that most of our household appliances need AC power to work properly. Inverters also help to regulate the voltage and current coming from the solar cells, ensuring that the appliances receive the correct amount of power.
The inverter is a device that uses various electrical and electronic components to make the direct current (DC) input oscillate at a frequency of either 50 or 60 hertz. The output of the inverter is a sinusoidal current called alternating current (AC).
When the DC power from the solar cells is converted to AC power, our home devices can use it to operate properly. Therefore, the inverter does an important job in a solar energy system.
