If you are just using your battery
and the trailer is not plugged into 110v ,your electric outlets will NOT have power.
If you are plugged into 110v , flick the switch on the converter for 110 V and your lights
and electric outlets will work.
Hope this helps , I have two , trillium
4500. and 1 ,1300 . they all work the same.
