On our 2015 R31-CB, we have no 120 power while running . All else appears normal. We do have 120 while plugged into shore power. The two breakers behind the rear seat have not flipped. Where should I start? Thanks.
 
I’m assuming that you have flipped the inverter on while underway?
 
Do you also have a generator?
 
Not sure about the 2015 model but there is also a large red switch near the inverter/battery charger that will need to be on. You might check out the Ranger systems and operations videos for the R31 on their website they have a lot of information on the power systems

 
We have a Mastervolt inverter/charger on our R31. We do have a generator. The inverter only works on shore power (automatically) & will not turn on when disconnected (while running).
 
When shore power is disconnected, what does the KISAE control panel show? If operating correctly the display should show the battery voltage and have an orange over green status light. indicating the inverter is on and supplying 120 V AC to your outlets and microwave.
