6A, 6V Relay Solar Charge Control

This 6V solar charge regulator meets most small-scale 6V application requirements. With a current rating of 6A, it can handle up to a 50W solar panel. Its principle of operation is very simple and there is only one adjustment: cut-out voltage. Many inexpensive commercial solar charges available use, I believe, this technique. However, this particular […]
