Disconnect the DC switch of each PV string connected to the inverter, and use a multi-meter to measure the voltage of the PV+ to ground and PV- to ground of each string. This will identify which string has the ground fault.

Compared to 12V or 24V systems, 48V inverters offer the best balance of efficiency and safety, especially when dealing with higher power demands. 48V systems don't carry a lot of current through the wires (which can lead to heat loss), but instead use lower current at higher.
