PROBLEM TO BE SOLVED: To facilitate maintenance and inspection of only electrical components of a power supply device which need the maintenance and inspection. SOLUTION: The power supply device 1 has a built-in inverter 3 which converts DC power generated by a solar battery into household AC power in a box 2. A first electrical board 11, on which the electrical components which relatively do not need the maintenance nor inspection, and a second electrical board 15, on which the electrical components which need the maintenance and inspection, are provided in the box 2. The second electrical board 15 can be detached from the box 2 relatively easily in comparison with the first electrical board 11. |
