just starting to put together a solar system, i have 16 panels on two strings on a barn roof, double pole isolator as they come into the shed, then 10mm 4core swa to the house where the 8.8kw inverter will be. i know the inverter has surge/lightning protection but as i'm going to put another isolator on the end of the swa i would like to add some more protection, what's the best, mcb,s fuses in everyone's opinion?

thanks
