電源自動切替装置第2号 Automatic Power Switching Device No. 2

個人でできる環境対策、電気の地産地消 (5):

自作した2台目の装置のテストを太陽光発電・蓄電装置に接続したエアコンで行っています。

主電源をこの太陽光発電・蓄電装置に、副電源を商用電源に接続していますので、仮に主電源（蓄電池）からの電力供給がゼロになれば、自動的に商用電源に切り替わりエアコンは運転を続けます。

自家発電電力の100%自家消費には欠かせない大切で不可欠なスイッチ道具です。

Environmental measures that individuals can take, local production for local consumption of electricity (5)：

I have been testing the second device (switch) I have made by myself on an air conditioner that is connected to the solar power generator/storage power supply system.

The main power supply is connected to this solar power generator/storage power supply system and the secondary power supply to the commercial power supply. If the power supply from the main power supply (battery) from the solar generator drops to zero, the air conditioner will automatically switch to the commercial power supply and continue operating.

This is an important and indispensable switching tool that is indispensable for 100% self-consumption of self-generated power.
