I need help designing my system. How many MPPT do I need to use for a 6KW Pv system 48 V. The panels (18) are 360W each with 47.70V (Voc), Isc 9.56 Amps. Please upload a schematic or wiring diagram if you have one.
Thank you

You will need 2 150/75A MPPT's - 6kW at 48v is 125A. 2 off 75A chargers will give 150A total to allow for some spare capacity. At 47.7V Voc, 3 modules can be connected in series to stay in the 150V limit. So there are 3 strings of 3 modules to each charger, you will need 15A fuses in each leg of each string for module protection. Make sure that wiring is of adequate size and type.
