There is usually a switch to turn off the invert function on your Inverter/Charger/Converter (Inverter) inside the coach.
My on/off switch is on the Link 2000 panel, and was a separate toggle switch before the Link was installed.
On my "Inverter" the switch on the "Inverter" box is always off allowing the Link 2000 remote panel switching to operate. You could turn off that switch on the inverter itself, if it is in the "on" positon.
