SmartSolar 100/30 will not get to programmed equalization voltage 16.2v. It will only get to 15.3.
When the charger is in the equalization phase, how much current is flowing?
In section 3.8 of the manual it describes the conditions for the equalization phase.
The equalization current is limited to 8% (2.4A) for the default battery type or 25% (7.5A) for a user defined type. If this current is not enough to lift the Voltage to 16.2V then perhaps your battery bank is large or maybe it has got problems.
You are right, it shouldn't need very much current to get to equalisation Voltage, if it does, then something is up with your battery bank, that is why there is a maximum current limit for the equalisation stage.
I don't know how big your battery bank is, but 18A sounds quite high. Do you have any loads connected when doing an equalisation charge? These loads will be taking current too.
Additional resources still need to be added for this topic
