I've some MPPT100-20s connected to a Cerbo via VE.Direct and VE.Direct/USB cables.
At some stage I might have to temporarily add a bluetooth dongle to the MPPTs to change settings. Obviously this involves unplugging the VE.Direct/(USB) cable first.
Can this be done while the Cerbo and MPPTs remain turned on, or is there a risk of blowing something up during hot plugging?
Cheers
