Abstract— Improvement of multifunctional converter of the photoelectric system with storage battery for the object connected to a grid with multi-zone tariffication is considered. The structure of control system which uses the slave current control loop of the grid inverter is proposed. Voltage stabilization on the inverter input is achieved by the current regulation in the common coupling point or photoelectric battery current or storage battery current by connecting the appropriate voltage regulator. This provides the high performance while maintaining a power factor close to 1 at the common coupling point of the object to the grid. Blocks of adjustable limitation were introduced into the channels of formation of the reference value currents of grid and storage battery. A task block with switching to battery forced charge mode is introduced too. The structural changes is carried out with taking into account the degree charge of storage battery, possible value of maximum power of photoelectric battery, achievement of levels of limitation of the reference grid current and voltage at the inverter input. This allows to regulate the energy consumption from the grid (generation to the grid) and expands the possibilities of redistribution the energy consumed from the grid at low tariffs during peak hours. The results of simulation in Matlab, which confirm the efficiency of the proposed solutions, are presented.
