自作電源自動切替装置 Home-built Automatic Power Supply Switching Device






Home-built Automatic Power Supply Switching Device:

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.
