Hi full_mosey,

To me 60% of the amp hours would be 60 amps on a 100 amp-hour battery. At 12.8 volts that works out to about 768 watts. I guess I don't follow the logic.



Is your ratio Wsolar/AHbattery, or Asolar/AHbattery?

Using your rule, how many Watts solar would I need for a 5AH battery?

I figure 3W. If that is not correct, then maybe you can tell me where I misunderstand. :)

HTH;
