I have read allot of threads on this and unless you have strings in parallel, disconnects aren't required before the PV feeds land on the inverter. Still, I plan on putting disconnects at the arrays, along with the 15 amp fuses, 1 each per 8 panel string. I would also like to have a way to shut the PV down, before the XP and before the feeds land on the terminals so the terminals aren't hot if I need to take the covers off and work on it.
On the coldest days, panels would be supplying 435VDC at 15 amps I would prefer DC breakers over manual disconnects, (auto shutdown if something happens) something like 500volt at 15 amps. Is this a good idea or a waste?
