Solar charging - can it be so?
I'm still trying to wrap my head around the solar and power issue, but I have learned a lot. In conversation with my RV service tech, an independent guy who takes pride in his knowledge and work, I wa...

See my 7:03am post today. The bypass diode acts like a direct short with 0V and conducting all amps. Well OK there is a small voltage drop (0.3V) across the diode. The other 2 panel sections are still producing 10V each with the amps.
So a panel that produces 6 amps at 30v (full sun) would produce with partial shading 6 amps at 20v. How is it possible that a panel operating at 2/3 can still produce 6 amps.
MPPT controllers convert power (watts) for the load, PWM controllers pass amps to the load.
Hope this helps.
