The issues of ensuring compliance with the requirements of IEC standards of current quality at the point of common coupling of a local object with a photovoltaic system to an AC grid are considered. Wherein non-sinusoidality of grid voltage and non-linear loads of the object in case of use of multifunctional grid inverter are taken into account. The structure of the inverter output filter is improved and its parameters are justified. The possibility of coordination it with the grid parameters is shown. It allows to increase the compensation efficiency of higher harmonics of the filter capacitor current at the point of common coupling to the grid. The structure of the control system has been improved with the introduction of current coupling of the filter capacitor into the channel of the inverter current reference forming. A model of the system “grid - inverter - load” for researching processes in the system is developed
