The invention relates to an intelligent photovoltaic header box and a manufacturing method thereof, belonging to the technical field of photovoltaic power generation applications. The technical scheme is as follows: an anode output of a solar battery is connected with an anode bus bar (3) by an acquisition and control circuit, and the anode bus bar (3) respectively outputs to an anode input end of a direct current breaker (5) and an anode input end of a direct current lightning protection device (6) through two paths; and a cathode output of the solar battery is connected with a cathode bus bar (4) by the acquisition and control circuit (2), and the cathode bus bar respectively outputs to a cathode input end of the direct current breaker (5) and a cathode output end of the direct current lightning protection device (6) through two paths. The voltage, current, power and other parameters of the solar battery which is converged can be measured, the states or invalidation of the direct current breaker, the lightning protection device and other elements can be detected, and the header box adopts the photovoltaic battery voltage self-supply mode without mains supply, thus effectively solving the problem that the post-maintenance of a megawatt-level power station is complicated, and ensuring the stability of a large photovoltaic power station system.
