voltage issue (1 Viewer)

While i've been 'playing' at fitting my new solar panel I have noticed the sargent control panel shows about 0.3V less than the actual batteries are. Is there any reason and can it be put right?:thumb:

I don't think most panels are particularly accurate. Mine reads low by about the same as yours. As long as you know how far out they are it's not really a problem.

Voltage drop across the cable from the battery to the panel. Normal
