Gary, It was not too late as I wanted a maint free anyway. I solved the battery too big for the battery space problem. I ran the batt cables out through the louvers and put the batt in a Tupperware batt box. It will look better when I build a decorative facade/miniature enclosure bld for the genset. I will have oodles of open surface area (louvers) at the intake and discharge ends and a removable front and top for full access to all removable panels on the genset.

I ran it and it sure is quiet for 17 kW. It started the first time so fast I couldn't get my finger off the switch before it started. Now to wire it up. I have an electrician who is going to help me evenings and weekends to wire it up and do several other little projects starting Monday.
