Anyway this is what I learned (and was looking for).....
The 2A reading is what was "being sent" to the batteries, even though it is sunny that is all the batteries needed at the time. When I turned on some lights and that number changed to 3.4A that is what was "being sent" to the batteries to compensate for the power being used.
Don't know if I explained it right but I understand now.
No. The amps for the lights go to them and not to the batteries as compensation. Any amps left over go to the batteries if they want any.
The amps to the lights might go via the battery posts as wiring connections, but do not go down into/through the batteries like "amps to the battery" do.
You can have the batteries wanting 5 amps and solar putting out(EDIT--scrub that!--make that "able to put out") 8 amps and turn 10 amps worth of lights on. The lights get their 10 amps, the battery not only does not get its 5 amps but has to supply 2 amps to the lights.
The controller will show 8 amps output, and the battery monitor will show minus 2 amps.
If you want the batteries to get anything you have to reduce the load (lights etc) to under 8 amps. At 3 amps for lights, now the batteries get 5 amps, which is all they will accept anyway. So you have 3 "free" amps to do something with.
