摘要：<p>PROBLEM TO BE SOLVED: To simplify assembling works by a method wherein there is arranged a disconnection device and a crosscurrent preventing diode in response to each string circuit of a solar power generating system on a printed board in a box main body. SOLUTION: A printed board 3 is attached to the main body inside a box provided with an outer door, and 6 pieces of disconnecting devices 4 and 6 pieces of reverse current preventing diodes 5 are attached to the printed board 3 in response to each string circuit together with an input terminal stand 6 and a surge absorber 7. Since the reverse current preventing diodes 5 generate heat, a through hole 9 for passing a driver is provided in the printed board 3, and after the printed board 3 is attached to a heat sink 8 functioning also as an apparatus attaching base, the driver is passed from this through hole 9, so that the reverse current preventing diodes 5 can be closely fixed to the heat sink 8 and be fixed thereto.</p>
