Can 48/8000/110-100/100 be set to 120VAC?

I originally set up my boat system with two of the 5kVA 120VAC Quattros, but I'm annoyed at the max charge of my 48V batteries being about 60A per Quattro. I see that there's an 8kVA Quattro with up to 110 amps of charging each (and the 6400 watts can easily sustain that), to nearly double my charging speed, but it looks like it's 230/240VAC only. Has anyone tried setting the output voltage in the VE.Configure or other choices, and seen if it will go lower?


I know that I could rejigger everything to have an autotransformer on the way in and the way out, but that's adding a lot of complexity to my system.

you can set the max charge rate by using the ve config software, from default these are set to 52A NOT set to max which is 70A

this is showing a 48/5000 unit so the 8000 will be higher

its the same charge output for 120 or 240 Volt units

I have already set the max charge rate to 70 amps. But it is limited to only drawing 4000 watts. It pulls 4000 watts charging at about 60 amps (I guess it's only ~85% efficient?)
