FIELD: power supply to domestic appliances of off-line users. SUBSTANCE: system has solar battery of m sections, n storage batteries with individual charge-discharge devices, series- connected voltage regulator for feeding solar battery loads that has m channels; each section of solar battery is connected through isolating diode to respective voltage-regulator channel; all sections of solar battery are connected through other diodes to common bus which is connected to power inputs of all charging devices. Number of voltage regulator channels individually controlled from control unit incorporating regulator channel displacement control range is same as that of solar battery sections; voltage limiting device is mounted in parallel with each solar-battery section. EFFECT: improved reliability, reduced output-voltage ripples and power loss including at system failures, eliminated surges in input circuits. 6 dwg
