Photovoltaic combiner box backflow prevention

Solar combiner box help

I have 3 strings each is 600w 10Amps (I believe a combiner box is over kill on this system but I wanted to be able to isolate each string for testing and maintenance) I have made a box with 6 fuses each one is 15 amp, one on each positive and negative wire. Now I see some boxes have diodes to stop power flowing the wrong way, my question is :
