Do I need protect negative wiring between PVs & inverter with a fuse or breaker?. Should the GFP on positive wiring between PVs & inverter be placed ahead of or after the breaker? Thanks

Negative typically isn't fused (assuming negative ground system). Some charge controllers (eg Midnite classic) have GFP built in. If not, between the pv breaker and the charge controller I think.Off-grid.

Can you tell us more about your system, any components you have purchased our are thinking about purchasing?
Is this in a vehicle, cabin, or other? DC loads and\or or AC inverter?
Grounding is a complex subject. If done wrong, it can be worse than doing a half way job.
