This paper presents a multipurpose photovoltaic (PV) system using a lattice wave digital filter (LWDF)-based control advance. The various PV system is developed for integrating the active power to the distribution system with variable PV in-solation and correcting the nonlinear loads connected at the point-of-common-coupling. The PV system is multifunctional; therefore, it serves various purposes. It injects the active power of solar PV array to the grid. It extenuates harmonics of loads and provides grid currents balancing. The PV system incorporates a PV array, a boost converter, a voltage-source converter (VSC), a nonlinear load, and a distribution system. The boost converter is utilized for maximum power extraction from PV array using an incremental-conductance-based maximum power point tracking technique. To ascendance the grid-tied VSC, an LWDF-based control approach is proposed. Also, this advance can produce the desired sinusoidal fundamental component of load current to estimate the grid reference currents. The aim is to implement this control as it has many properties like low-pass band sensitivity, good dynamic response, and a decrease in a dc-offset noise error. The varieties of experimental results are presented to validate the control of a PV system
