The present invention relates to a system to control an inverter connection board and, more specifically, to a system to control an inverter connection board, which can maximize the efficiency of a photovoltaic system and maximize the lifetime of a switch and an inverter provided in the connection board. According to a preferred embodiment of the present invention, a system to control an inverter connection board includes: an inverter circuit unit which converts direct current generated by solar cells into alternating current which supplies power to a load in connection with a commercial grid-connected power; a first switch connected between an output terminal of the inverter circuit unit and the load; a current detection circuit unit which detects a solar cell output current value; a voltage detection circuit unit which detects a solar cell output voltage value; a power detection unit which detects a solar cell output power value; and a control unit which controls the inverter circuit unit to stop and the first switch to be open when the solar cell output power value is not more than a preset reference power. |
