Logging maximum current in the Midnite 150

[slferris]

I need to monitor the maximum current that my Midnite 150 experiences, especially during cold weather, in order to decide whether to add more solar panels to my array.  My old Outback controller "remembered" maximum amps and displayed the number for me to read.  I notice that the Midnite 150 "remembers" maximum watts, but is there any way for it to "remember" maximum amps and display that information?
