ME-ARC "Max Charge Amps" vs "Max Charge Rate"

What is the difference between these two settings? They both end up specifying a maximum amperage (either as a percentage or an actual number of amps) to the batteries during charge.

01D Max Charge Amps – This menu setting is the maximum current allowed to charge the batteries during Bulk, Absorption, Float, and Equalize charging; and is provided to limit the charge amps. Default setting: Amps = 200 ADC Range: OFF, 20-990 ADC

03E Max Charge Rate – This setting is the maximum charge rate allowed to charge the batteries during Bulk, Absorption, Float, and Equalize charging; and is provided to limit the charge rate to the battery bank to prevent battery overheating caused by charging at too high a charge rate. A 100% setting uses the maximum charging capability of the inverter/charger to charge the batteries if needed, while a 0% setting minimizes the charging current while continuing to allow pass-thru current. The Max Charge Rate setting is provided as a percentage of the inverter/charger’s maximum charging capability. Refer to the label on the side of the inverter (or owner’s manual) to determine the inverter’s maximum charge rate. See the example below for information on how to determine your inverter’s Max Charge Rate setting. Default setting: 100% Range: 0-100%

I found this in post #18 from this thread...

http://www.irv2.com/forums/f103/ms28...-472214-2.html

The 01D is to adjust max amperage if using other charge sources like our PT-100."

I have an email into Magnum to confirm this.

From Magnum....

01D Max charge amps is a setting to make sure all charging from solar or our chargers do not push amperage above max of bank with all chargers.

03E max charge rate is when ac is applied to the inverters and those chargers are bringing voltage up on bank.
