I am planning a ~400v string of panels to connect directly to a motor controllers power supply. Maybe 3-7 amps.

What kind of diode and fuse or breaker might I use for this?

Also the load does not have an on off switch so should I use a normal DC disconnect for that purpose or is there a better option to avoid sparks?

What function would the diode serve?
