Thanks. I will individually protect probably with inline auto-type connectors. MC4 stuff (as is most solar) in NZ is way overpriced. I just chop them off and solder. 

The wire is 8 AWG or 8.31 sq.mm. The second question is no, the modules are wired directly into the combiner. Total combined amps is 42.3.

The wire is 56 amp and there's about 10 foot of it. Do I need overcurrent protection? I have five panels and the largest current of any of them is 8.88A @ peak power.

My panels output 43 amp continuous but I've manged to blow two 50 amp fuses in as many days. This happens after a cloudy start to the day after which the clouds disappear and then very good sun. I ex…
