Solar panel detailed system design / item list and circuit design

I have 20 off Monocrystalline solar panels each of 50 volts 7.5 Amp hrs and want to establish the best circuit diagram for the system.

I also have an APC UPS Galaxy 3,500 which is 3 phase in and single phase out (240v) It also has a single phase bypass output.

You should be an expert industrial electrical engineer as the grid needs to approve your design.
