The authors have considered the methods of summing the energy of solar cell and rechargeable battery here by invert-transformer converters with intermediate high frequency link which allow matching sufficiently different the levels of source voltages with load.It was shown that the structure with addition of inverter output voltages in general loop allows controlling solar cell voltage in the range sufficient to implement the mode of maximum power take-off.The adjustment characteristics of the converter at specified voltage-current relationship of solar cell and different load values were obtained.The authors determined the conditions of the most energetically favorable source power distribution which corresponds to minimum power of rechargeable battery and peak power of solar cell.

It was shown that in such systems the position of neflintw-r6mpw a set point of solar cell voltage-current relationship depends on load resistance.The authors made the conclusion and discussed the results.
