[Rhodes22-list] solar charge

[Mark West]

Cary  if an amp  meter was in line I think   amps are measured by amp hr?  what do you expect amp would   be   83/60=1.5amp+or- ? its been 45 years since I had electronic class  thanks for your input. Mark

Solar panels are rated by watt output. WATTS divided by VOLTS equals AMPS.
You will need 240 WATTS at 12 VOLTS to achieve 20 AMPS.
By the size stated it seems your solar panel should be a 10 WATTS system.
This would yield point 83 AMPS.
