In the recent times, solar power is a promising replacement to fossil fuels. However, a number of factors, including the amount of solar irradiation and the absence of sunshine at night, reduce the efficiency of solar power. The MPPT approach is employed here in order to solve this issue. In a grid-connected solar energy system, transformerless PV inverters can be used because of their high efficiency, reliability, power density, low cost, and reduced size. However, the presence of a transformerless system will result in leakage currents, which is unacceptable in grid-connected applications. This research uses a H6 inverter, a modified version of the HERIC inverter, to reduce leakage currents. PI controllers are utilized to synchronize the H6 inverter and the grid. For grid-connected applications, this study intends to utilize solar energy and reduce the leakage currents produced by transformerless inverters, which are commonly used. Solar, a transformer-less step-up converter, and an h8 inverter are all integrated into one unit. The idea is to maximize the use of renewable resources, which reduces the demand on the grid.
