Never disconnect the battery
What Mr Wiz was really telling (I think) was - not to disconnect the battery while controller is still connected to the panel. Disconnect the panel input from controller first (or, indeed, cover the panel).
Strictly by the book, controller should have a fuse after the controller, then - Pos buss, and from there - Pos lead to the battery, with another fuse close to the battery.
With a small panel you don't need any fuses before controller, only "some" disconnect - to disconnect the panel if you plan to remove the battery.
