I have a question that I hope some one here can help me with.
I understand that due to the internal resistance of a led acid battery,
one can never expect to get the full charge potential to go from your
Solar Panels to your batteries, and I have observed that the current
flow to the batteries also depends on the state of charge in the
battery. but given that a battery is 50 percent discharged, using a
conventional solar panel designed to charge 12 volt battery, how much
current will actually flow from the panel to the cells, and how much
does it vary from an L16 battery Vs a T105? I suppose it goes with out
saying that more batteries will result in a better transfer of power,
but it would help me to know what kind of losses in current to expect.
excluding the other chemical inefficiencies.
The bottom line here is I was wondering if I could get away with a 20
amp charge controller, if my panels had the potential to put out 22
amps, since only so much current will actually pass to the batteries.
Thanks. Dave
