MPPT CC connected to the PV without batteries

[malevo]

Hi, totally newbie here. Yesterday I connected 2 solar pannels in parallel to a Tracer 2210RN mppt CC, and accidetally connected first the PV and then a few minutes later the batteries. Did I made any damage ? the CC seams to work fine, but I'm worried about it.
Thanks, Pablo

It was the wrong order of operations. Panels are the last thing connected, and the first to get disconnected. It is possible to damage, but 9 out of 10 times just makes the Controller Go Stupid. Disconnect and connect in the right order will RESET the Controller once it knows what battery voltage it is using and initializes from battery power.

Sounds like you are OK if it is working correctly
