The blue plot is what 30A "DC" current flow looks like through my Outback Radian GS8048A in grid-tie mode. The green plot is the current flow from a Morningstar TS-600-60 charge controller working as hard as it can in MPPT mode to supply all the current demanded by the Radian.

The waveforms were captured with my two-channel digital storage oscilloscope, stored onto a flash drive and read onto my PC, and then run through a 1024-tap digital lowpass filter that I implemented in Python to get rid of the considerable noise that was present for the low-amplitude voltage developed across a shunt with only 100 micro-ohms of resistance. The plot is scaled to Amperes.
