PURPOSE: A smart grid system using solar power generation and a composite solar power generation controller are provided to reduce power consumption by supplying power to a general load and an illumination load using a solar energy generating apparatus. CONSTITUTION: An MCU(Micro Controller Unit)(110) controls a system. A relay controller(120) varies input power and output power according to the MCU. A solar energy generating apparatus(200) uses sunlight and generates power. A grid(300) inputs general common power. An LED illumination(600) uses a DC(Direct current) and emits light. An LED driver(160) is arranged between the relay controller and the LED illumination and drives the LED illumination. A SMPS(Switching Mode Power Supply)(161) for AC(Alternating Current) to DC conversion changes an AC, which comes out through the relay controller, into the DC. An inverter(710) is connected between the relay controller and the general load and converts a DC, which is inputted through the relay controller, into an AC. |
