An output control system for a multi grid connected generation device is provided to prevent deterioration of power generation efficiency and disorder of the power generation device due to output suppression as protection function operation by preventing generation of over voltage through the output control of the individual power generation device. An energy source(21) generates DC power and AC power. A power converter(22) provides the DC power and AC power to an AC load(23) and commercial power. An output control unit(24) is connected to the power converter(22) and controls output. A power generation unit communication part(25) is connected to the output control unit(24) and has a communication function. A power generation load unit(20) includes the AC load(23) connected to the power converter(22). A measuring circuit(31) measures voltage, current, power, power-factor, and harmonic wave of a system for controlling the output of the power converter(22). An A/D converter(32) converts an analog signal outputted from the measuring circuit(31) into a digital signal. A command controller(33) provides a command to the output control unit(24) to control total output voltage. A time synchronizing unit(35) generates and provides synchronizing time to the command controller(33). A command control unit(30) has a command unit communication unit(34) to transmit and receive signals with the power generation unit communication part(25).
