OK, I'll speak up since I was mentioned by association. :) I see two
problems with a current meter for DC as I see only 2 ways to make it happen.

1. shunt resistor, and measure the voltage across the shunt, calibrate meter
to that. Yes, it works, voltage drop does increase with load. I suppose
the remote sense on the power supply (if equipped) could be connected past
the shunt.

2. expensive DC clamp arounds. These are more expensive than their AC
counterparts.

And, since current draw is a somewhat static thing once modules are in
place, what makes more sense to me is to make a small spreadsheet as some
have done to monitor their power supply loading. I can't see losing any
panel space for it.

Translation: Don't look for anything from Stooge-land anytime soon.
