DC to DC charger and standard alternator in a 2016 gen3

Hi all. some help please Im currently researching (learning as I go) and putting together a solar set up for my 2016 Jimny. What started as a simple build has become rather more uprated with the wifes demand for a 1800 watt hairdryer capacity ! I now have a 20 amp DC to DC charger and a 100 watt solar panel, to 2 x100ah lithium batteries, 3000 watt inverter.. Now wanting to understand if a 30 or even 40 amp DC to DC charger would be possible without upgrading the alternator. I have no other modifications putting extra demand on the alternator. Without straining the standard alternator would this upgrade to 30 or 40 be ok ? Thanks in advance.
