Would you please advice that which UPS model and how many UPS should be used on each solutions? 

Solution 1(4770.77 Watts): Need Runtime 30-60 Minutes, I split it with 2 sets of UPS. 

Please use 2 sets of OL3000HV+(2)BP72V18AH for 4800W for 45 Min. with rounding or OL3000HV+(3)BP72V18AH for 68 Min. with rounding. 

Solution 2(111.75 Watts): Need Runtime 30-60 Minutes, OL3000HV (9AH) is enough to cover 111.75 Watts more than 60 Min.
