From my view point I don't see multiple parelled sets of 4/0 PE breaking at once. Considering all the PME supplies...
Is "4/0" a reference to AWG? About 100mm²?
Perhaps not, but I don't think there's anything in the digram that suggests the size of the system or that conductors are to be paralleled - it could just as easily be applied to a small system - say a domestic off-grid setup with multiple sources where perhaps something closer to single 1.5mm² conductors might be the order of the day.
