Safety of High Voltage portable panels?

I'm wanting cable runs up to 20Meters or more for my portable folding panels and no thicker than 10GA wire. And using anderson plugs as they are quick connect, I normally just hot plug them into charge controller input.
I currently have 3X 300watt 22voc folding panels wired in parallel to my victron mppt. Apon setting up panels I normally just plug the cable ends into panel & into CC. There is a 50amp toggle DC switch right before my CC for convenience. Although hot plugging anderson plugs with the switch ON doesn't seem to hurt them at low 17 volts.
I'm wanting to re-wire each panel's wiring to series so they each would be 66voc total. How dangerous is this with hot plugging anderson plugs? I read about arcing when doing this but not sure.
What fuses do I use? All auto style fuses I use like midi & blade are limited to just 32volts.
There don't look to be any DC toggle switches for this voltage, so what else should I use as a switch?
Perhaps MC4 connectors are they way to go on the panel's end where there will be no hotplugging, as anderson plugs are open & in the wet one may get an electric shock standing next to panel?
What else is dangerous?
