What does your Freedom Panel say?
Does it show Charging, what is the voltage output?
You should have either a BIRD or BCC, which controls a Isolater relay.
Look closely at the B+ terminals or the batteries (12 V to Ground Terminal), do you see a Wire with a fuse. Is it clean?
This wire is the sensing voltage which informs the BCC or BIRD that the charge voltage is at a high enough level to close the Isolator relay.
Do you have a diagram?
Also, read the voltage on the Red & Black terminals of the Xantrex, is it above 13.5 Volts. Trace the wire from the red,
