Its primary function is to convert direct current (DC) electricity, which is commonly stored in batteries or generated by solar panels, into alternating current (AC) electricity, which is the standard form used by most household appliances and industrial equipment. DC power is commonly used in electronics like batteries, sensors, and motors, where a stable power supply is required. Alternating current (AC), on the other hand, fluctuates over time, following a sinusoidal wave, represented by a green line on a graph. This allows us to utilize the stored energy to power appliances that require AC supply.
