<P>PROBLEM TO BE SOLVED: To improve arrangement and mounting structure of circuit breakers in order to achieve miniaturization of a power collection box, miniaturization of a casing which forms the power collection box, and furthermore, easiness of performing wiring in the power collection box in the power collection box by which DC power from a solar battery string is supplied to a DC/DC converter via the circuit breakers, and which supplies the DC power to a power conditioner via an output terminal. <P>SOLUTION: A circuit breaker area provided at the side of a DC/DC conversion circuit area is provided with a circuit breaker mounting platform in which an upper stage mounting part where two circuit breakers are arranged at upper positions by horizontal arrangement, and a lower stage mounting part where the remaining circuit breakers are arranged at lower positions among circuit breakers provided for every DC/DC conversion circuit are formed. The circuit breakers are like the level difference that the upper stage mounting part extends to the front direction of the casing to the lower stage mounting part, and lead wires to be connected from the circuit breakers at the lower stage mounting part to the DC/DC conversion circuits are wired by getting under the rear side of the upper stage mounting part. <P>COPYRIGHT: (C)2013,JPO&INPIT |
