3 Simple Solar Panel/Mains Changeover Circuits

Last Updated on January 2, 2024 by Swagatam 40 Comments

solarpanelmainsAVCchangeoverrelaycircuit

The discussed automatic change over relay circuit was requested by Mr.Karimulla Baig. The circuit normally charges the connected battery at constant current through the power received from the solar panel, and reverts to DC power from an AC/DC adapter in the absence of solar energy (during night time). Let’s the read the request in more details: Technical […]
