Morningstar 30amp solar charger display
The digital display on my Morningstar PWM 30amp solar charger shows battery volts and amps. When the display reads 7amps is that telling me what the panels are producing or is it the amps that the bat...

OP - in case if waters got too muddy - your display shows "controller output". The total of current going to battery and to loads. Current going to battery can be lower than what it "can accept", if there isn't enough sunlight or the loads are stealing the current.
With PWM controllers this "output" is practically identical to "controller input", minus very low self-consumption current needed to feed the controller itself.
Peak output of the panels (and the controller output) could've been much higher or lower few hours earlier, but you wouldn't know this if you weren't looking at it at that time, because Tristar display is very basic. Despite the cost. To see daily output graph you need to buy the adapter for monitoring this on laptop. Not terribly important.
