Solar panel

You said "inductance is an AC thing...". Actually you wrote "a AC thing" but I'm not the grammar cop.
I guess I should have been more direct and replied "inductive reactance is an AC thing, inductance affects both AC and DC circuits".

I continued by providing a few examples where "inductance" in a DC circuit can be either beneficial or detrimental. You somehow interpreted this as I implied a LR filter suppresses back-EMF. You might want to re-read my post.

As far as DC motors not having the capability of creating detrimental EMF, some guy named Lenz might disagree. I sure could have saved the company a lot of $ not designing in those flyback diodes.

I could have saved them millions by not including those worthless little inductors on the DC power input pins of all those hot-swap signal conditioning modules. I would have been a hero.

And then, to finish it up, you accuse me of some scare tactic to get OP to spend a buck fifth on a blocking diode? WHAT?

Solar panels are already designed WITH a "blocking diode" which is there to prevent the panels from draining the battery source when the sun doesn't shine.

Adding another diode to the chain isn't going to "protect" the panel and just wastes and robs you of .7V of the panel voltage.

As far as "inductors" goes, have worked with many high power/high torque stepper motors (all PWM DC voltage by the way) used in very large robotics systems (some of these are the size of a average room in a home). Not once has there been any "series or parallel inductors" involved at the motors or in the motor drive electronics.. Those motors propelled 500+ lb gripper assemblies up and down the track up to 20ft in length at a speed faster than you can run. Motors and controllers tend to live very long lives, had more issues with gearboxes and cable failures..
