I'm reading inconsistent advice regarding over-current protection in solar systems.

Suppose I'm had a pretty simple system:

solar panels => MPPT controller=> LiFePO4 battery => house loads.​

I'm going to need a class T fuse at the positive post of the battery on the conductor to the house loads (plus additional fuses or circuit breakers in the house wiring).

But what OCP do I need on the solar side?

What do I need between the panels and the MPPT controller?

Between the MPPT controller and the battery?
 
Spd= surge protection device
Pv= photovoltaic/ solar collection
Scc= solar charge controler either mppt or pwm typically
