OK, I am doing a preliminary test to make sure I didn't put my foot in my mouth. Drew my 450 AH bank down to 11.8V. Pulled the plug on the solar and plugged in the Iota 45 With IQ4. It has been almost 40 minutes now and the pendant is still on rapid flash which means it is still in bulk mode. IPN remote is reading 42 amps and bouncing between 14.6 and 14.7 volts. I did not pull the fuse to remove parasitic draw. It started out at 43.8 amps but dropped to 42 in about 10 minutes. I will post again when it drops out of bulk but it looks like the 20 minute thing is incorrect. I thought it was in the past but never really put a clock on it.
