WARNING: do be aware that it is essential that the solar charge controller be attached to the battery at all times when the solar panels are attached. That is, disconnect the solar panels BEFORE disconnecting the battery, and reconnections the battery BEFORE connecting the solar panels. Charge controllers cannot be attached to the panels without a battery lest the controller be damaged.

Hummm, I unhook my fuse from controller to batteries to kill the solar input whenever I am on shore power, been doing that for years without issue, otherwise solar kicks on every morning and overcharges the batteries which are already up and in float mode. Maybe I've just been lucky.
