Re: Xantrex Controller: external events ?
Do not have a X CC, but on the OB and Midnite Classic (should ship soon), that control function is the Aux Output. Believe the Classic has TWO Aux outputs.
The XW CC should have one, but have not looked, yet. Altho, you may be considering a C-XX Xantrex CC.
If you can wait, and need an MPPT CC, the Midnite Classic may be worth the wait.
