OPERATION
The Freedom Inverter/Charger provides
120 volt AC power from auxiliary DC batteries,
automatic battery charging and automatic AC
transfer switching between an external AC
source and inverter mode.

3-stage battery charger, transfer switching,
and Power Sharing automatically function.

OFF.
If installed with the Remote Control Panel
or Link Instrumentation, the unit will be set up
