Schneider XW+ 6848 to 2 single phase generators

On a Grid tied system I want to connect my two single phase 120v generators to the XW+ 6848's AC2 L1 and L2 inputs so I can to help the solar panels charge my SimpliPhi 48v batteries during extended power outages on cloudy days. I guess my first question is "does the generator have to be a split phase 240v type or can I use 2 120v generators instead?". I have done all the wiring and the Inverter sees 120v on both sides of AC2. The Inverter says Qualifying, not Qualify Good. I have not simulated a power outage and am not sure how to further test this. I am assuming that the generators only kick in (I manually start them) when the grid is down and the batteries need charging or the system needs help with heavy loads.
Thanks

The better solution would be to use a single phase 240V generator without neutral to avoid any neutral bonding issues, using two 120V generators would result in an out of phase situation thus being regected by the XW inverter charger, at least that's my view.

1) difficult
2) resulting in both being in same phase, which would not work. They need to be phase locked in opposite phases.
You need to get a generator larger than 6kw Those often will have 240V output.
Is this for emergency use only, or battery maintenance in the winter ?
You do NOT want or need an "inverter" style generator, they are expensive but very quiet. Any good Contractor grade generator should work for emergency use. If you need extended days of running in winter, for house and batteries, you can either get 2 cheap contractor generators and split the run time between them, or get a higher quality off grid generator.
The more hours you anticipate needing the generator for, lower RPM generators will last longer. ( 1800 rpm or 650 rpm diesels)

FYI mcgivor I have 2 120v generators a EU3000is Honda and a iPower Yamaha 2000
" I found an inexpensive 120/240 generator non inverte typer, maybe that's all I need. "
Most definitely this is what you need. XW will not work with 120 gensets, inverter or not.. Even if synced and the same model gensets it will not be close enough. No use trying this, it was done 15 years ago and has not changed.
I only use the Honda EU 7000i 240vac with XW but any decent 240vac genset for north america will work if XW is configured properly. Back to the fire.....
