Question XP6000 Will Not Charge With Generator

Hello community, I have a pretty comprehensive writeup on my (2) XP6000 + battery + PV + generator system charging issue, although the system will not let me attach it here.  Is there a way to attach a pdf? 

I can't for the life of me get the inverters to charge the batteries when on generator.   Is this a known issue, and are there posts which address it?     A key aspect of the purchase was the ability to charge the batteries with the generator, and not being able to do that makes the system, well, not worth having.   

I have quite a few suggestions for EG4, as it seems like the equipment has the promise of being great, with the gap being firmware.  In some cases it doesn't seem to me that the changes are particularly hard, but would have a good payoff.  But in a casual look through the forum it seems like many suggestions are being made.  Is EG4 receptive and responsive to suggestions, and is there a structure for doing so?   

If suggestions aren't really being acted on I get it, although I still feel like I should get something which charges my batteries.  Any advice would be welcome.
