House Battery Charge While Underway

Once again I come to the best wisdom source to be found.

07 Holiday Rambler, 4 6v house batts, Magnum controller, Magnum inverter 2012.

Situation is, when we dry camp we run the gen for 2 hours when we stop, and another 1 hour in the morning. (might be more if we need the air)

Question is this. Should the house Batts not recharge from the engine alternator if we are driving from A to B for 300+ miles?

We have found looking at the control panel we are inverting going down the road.

Is there something we need to do different with the controller?
I find it hard to believe that after 300 mi we should arrive without fully charged house batts.

Thanks for all you do, you are all the best!
  • Yes they should. On the light panel, what happens when you start the generator? What happens when you run the engine? In both situations, there should be full charging "idiot" lights.

    But also, what are you running the inverter for? If you are using 120 volt power to run a fridge or other device, that does rob some of the available charging power, but your engine should produce enough.
