More questions on inverter and battery charging

I have posted on this subject recently so pardon for more. Here is more info. My inverter will not turn on without power. When i turn generator on the red light on inverter is on to fault with dead battery and when i scroll it also says low battery. No power is allowed to outlets connected to inverter. I have run generator for several hours but the fault remains. This is 2016 winnebago adventurer 38q so the batteries aren’t very old. I turn off power switches when not using in storage. Any ideas. In all my motorhomes never faced this. I have one solar panel and chassis battery is strong. Any additional thoughts/ thanks for all your help.

  • What is the battery voltage? Charging may not start unless you are above 10.5 volts. Can you run the chassis engine to let the alternator bring the voltage up a bit? Once at 11 volts fire up the generator.

    May need to go camping and plug it in and sort things out.

    You do turn the inverter off for storage right? Even with inverter off and switches off you may have a draw on the house battery.
  • Thanks. I tried to reset the inverter today but it went to fault quickly. I have it at my storage that also does service so having them look at it. Appears i have at least one bad battery.

    Try this. NO guarantee but if it works SMILE..

    Disconnect every power source.. 120 volt, turn off the breaker that feeds the beast.. 12 volt pull the fuse or lift the negative leade.. COMPLETLY shut it down (Remove all power SOURCES as well as turn the switch on the unit off)

    Count to at least 10.. Slowly... Or try a cup of coffee made before shutdown.

    Now reconnect power (Both types) and see what happens.


    Also as I said in the other thread.
    Measure battery voltage at the battery with a digital volt meter

    And again at the inverter Both when you first re-connect (Shoudl be same) and watch the meter when you turn it on and note the LOWEST reading.
