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...

When using a pwm controller, panel amps are either zero or full-on. Full-on would be the max current the panel can output given the irradiance conditions. Likewise, battery charging current is either zero or full-on.
Average current is dependent on the pwm duty cycle. If full-on current is 10A and duty cycle is 50%, then average current is 5A.
The rms current for a 10Apeak, 50% duty cycle is 7.07A. It would be incorrect referring to rms current is this instance.
