inverter/charger issues

Have a 2007 Holiday Rambler Ambassador. Remote for the inverter/charger shows a fault, ie overcharge on batteries & high tempature. Batteries are new and fully charged. I have power to the slides, but nothing else works. The battery switch to turn on 12 volt power will not stay on. Hooking up to shore power makes no difference. Will a bad inverter/charger keep both the house electrical systems from working? Also, the generator will not start or come on line. Need an idea of where to start, all this happened with no warning.

  • I have a class B and had inverter problems. First the solenoid by the inverter went out. I could not turn on the charger/inverter without it. I replaced it. Now my 110 outlets worked off the inverter but roof AC would not. Roof AC worked on shore power. Finally took it to a good repair shop. They checked it all over and the issue was bad inverter. It supplied basic 110 power when turned on but could not handle the power drain when AC compressor tried to start up. Luckily they had a used inverter to swap out with mine to find it. Bottom line in my opinion is that you need to be educated in all the ways the inverter chargers work or it will be very frustrating. I had a couple of other people look at it including a retired industrial electrician and a guy who tests high temperature ovens electronically and neither could figure out a way to test things. They both thought it was a bad compressor on the AC. Good luck.
  • Qualified no!
    Most large inver/chargers have a pass through function that would let 120 volt AC items wired into it to operate.
    Make and model of inverter/charger? It could have a reset button.
    Until you test the 12 volt DC to inverter/charger, you will no nothing!

    Maybe. It's not likely it affects 12v, but pass through ac won't work if your transfer switch is bad.
  • Here is my response from your other post:
    "First guess is batteries not connected correctly.
    Check for fuse in 12 volt DC feeding the inverter."
