I have a 2000w Yamaha and the 12v charging output is only 8 amps if I remember correctly. For your setup that's barely enough to maintain the charge of those 4 batteries. Rule of thumb is that you charge your batteries at 20% of your amp/hour rating. Since you have 4 6v batteries I can assume you have about 250 amp/hours so you'd want to fast charge at about 50 amps to 95% and then slow charge to 100%.
I have 2 6v Trojans each are 125 a/h. Because I am converting the 6v to 12v I still have 125 a/h. I should then fast charge at 25 amps to 95%. Either use a good battery charger or a good built in Converter to charge the batteries. The Progressive Dynamics converter has enough power to charge the batteries. The WFCO converter will not.
