This study suggests using a transformerless photovoltaic (PV) inverter connected to a single-phase grid. The inverter can operate in buck or boost mode, and it can get the most power from two subarrays linked in serial, despite the fact that each subarray is exposed to a distinct environment. When using an inverter that can operate in either buck or boost mode, depending on the application, it is much easier to construct a subarray with the fewest number of serially connected solar PV modules. This is why each subarray's power output increases as it is exposed to a new set of environmental conditions. This is what the design requires: the inverter's topology and control strategy must safeguard the common mode voltage from high-frequency components. This is done to keep the amplitude of the leakage current associated with the PV arrays within a specific range of values. It is also possible to achieve high operational effectiveness across the entire operational spectrum. Following a detailed investigation of the system that culminates in the building of a mathematical model, the project's viability is assessed through rigorous computer simulations. Along with a 1.5 kW lab prototype, other experiments must be conducted to ensure the plan's accuracy.
