To convert direct current (DC) into alternating current (AC), PV inverters, as well as grid tie inverters, are designed. Three major types of PV inverters are there but to help home appliances and power utility grids; each plays a similar role of transferring a charge. As compared to the actual solar panels, one negative of the inverters is the much shorter lifespan. This means installing a new inverter is necessary when to continue running at full capacity, it is needed to ensure the solar system is able.
