Can the charging current on an inverter/charger be adjusted?

I'm looking to build out a semi-off grid system for a cabin. I have a 2000w generator I'd like to use to feed the inverter/charger to assist with the battery charging. The datasheet indicates that it'll draw significantly more current than the generator can provide. Can the charge current be adjusted down in software? I see recommendations for buying a standalone AC charger, but that seems silly. I'm looking at the GroWatt SPF-3000 unit.

Depends on the line and model.

Page 16 of this manual (pdf) suggests the SPF-3000T's default is 80A and 10A-120A is configurable. I expect you'll have to read the manual/specs for each unit under consideration, a wise practice in any case.

Thanks, I guess I missed that when I read through. Good information!
