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%
