個人でできる環境対策、電気の地産地消 (4)、自作電源自動切替装置　Environmental measures that individuals can take, local production for local consumption of electricity (4), Home-built Automatic Power Supply Switching Device

商用電源と自家発電電源の切り替えを自動的に行うスイッチを作りました。

太陽光発電で発電し、蓄電した電源を主電源にして、これがゼロになった場合に自動的に商用電源に切り替えるためのスイッチです。

不要の電気製品の電線とプラグ、購入したモジュールを無償の収納箱に入れて配線しただけ、ですが。

おかげさまで、テスト、作動確認では期待通りの結果になりました。

小学生の図工の時間みたいに、何かを作るのは楽しいですね。

I have made a switch that automatically switches between commercial and private power generation sources.

The switch is designed to use the power generated and stored by solar power generation as the main power source, and automatically switch to commercial power source when the former power source becomes zero.

I just wired up the wires and plugs of the unneeded electrical products and the purchased module in a free box I had been given, though.

Tests and operational checks showed that the results were as expected.

It is fun to create something, just like in elementary school arts and crafts class.
