200kW off grid system compatiable with 300kva generator for one hotel in Burkina Faso

This project is installed in Burkina Faso. It is applied in one hotel where there is no grid connection. The hotel was powered by generator which is noisy and the gasonline cost a lot. Now the owner made his decision to go solar. 

He already has 144pcs 250W and 480pcs 150W solar panels, also he has 120pcs 12V200AH lead-acid batteries. 

What we provide is 1pc 200kW inverter, 6pcs PV combiner boxes(4 inputs, 1output) and 2pcs 360V200A mppt solar charge controllers. Everything works perfect for the moment.
