NOVELTY - The system has electric power converting section that converts electric power output in solar photovoltaic module into alternating current (AC) voltage. Cool air generation unit includes thermoelectric element for generating heat of low temperature than the outdoor air temperature. Control unit is connected to integrated control system with batch control, for controlling power source applied in thermoelectric element according to return value. The refrigerant supply hole and cooling water outlet are respectively formed in two sides of control unit.    USE - Solar cell generating system with inverter.    ADVANTAGE - The sealing air is circulated in the inverter door in order to improve the performance of the inverter among the essential element of the solar cell generating system, so that the efficiency and lifetime of the system can be improved. The overload occurrence by the air closure is prevented during the rotation of the cooling fan so that the noise and the vibration generated due to the overload can be drastically reduced. Since the cold air is supplied to the inverter inside instrument, the temperature generated in inverter inside instruments is dropped. Thus the humidity of the inverter main portion is maintained and the efficiency of the cooling fan and internal device can be improved. The lifetime of the solar cell generating system can be prolonged. The solar cell generating system can be steadily used without the abort by conspicuously improving the performance and life span of the whole inverter.    DETAILED DESCRIPTION - The vacuum portion is provided in the outside of the main portion, without receiving outdoor air temperature of cool air generation unit. Dehumidifier is provided at the inner side of inverter main portion, for controlling the humidity of the inverter inside. The solar photovoltaic module produces the electric power using solar energy into the direct-link line voltage of the system comprises the inverter main body and inverter door. A filter is installed at the lower portion of inverter door.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of outer shape of inverter.
