I upgraded my solar panel from 40w to 120w and l would like to measure the rate it is charging at.
I am an electrical anti talent. I know it should be charging around 6w/hour or so.
How could l measure it? I got an ancient analog volt-ohm meter but l got no idea how to use it. I mean where to attach it at the regulator?
I post a picture of the thing l call regulator which is 8amp by the way. I was told, it would handle the new panel.
It seems to work fine just love to learn how to measure the charging rate.
All help would be gracefully appreciated.
