This equipment system 1 has a power generation unit 2, a conversion unit 3, and equipment 4, which will be described later, and the equipment system 1 is always in an off-grid state.

Here, "always off-the-grid state" in the present invention means that the system (grid) K is not always connected (connected) to the system (grid) K or is connected to the system K at all times (at any time). It means that it cannot be done.
Further, the "system K" in the present invention is also referred to as a commercial power system, and is a system that integrates power generation, substation, power transmission, and distribution for supplying electric power to a consumer's power receiving equipment.
