Tripp Lite AWS2012SW problems

when I start inverter it runs as designed and then I start generator and inverter switches to charging mode
after charging for awhile it switches back to DC mode and will not switch back to AC and charging mode unless I shut the system down for a few hours

anybody have any ideas?

    My first thought would be that the AC goes out of spec (heavy start current loads?) and gets dropped. Don't know why you would need to shut down for so long though. Does it get hot?

    Some folks have found that they need to put (for example) a 100 watt filament lamp on the output of the genset to "stabilize" the output voltage and current.

    Do you have a meter that can measure frequency (Kill-a-Watt or similar)?

    It doesn't get hot, the generator is running rest of house that doesn't go through inverter

    I have a multimeter, and generator runs other lights so it has a pull from lights of several hundred watts

    Inverter has no issues in DC Mode, runs everything that is wired to it, I have 4 6 volt batteries that are also fed 500 Watts from solar panels, this inverter powers TV, DVD player, Cell phone booster and Phone

    Only issues is charging batteries in AC mode

    What is the voltage and frequency of the generator AC power at the AC in terminals of the inverter?

    What state are the status lights in?

    Is this a new installation, or did it work as expected for some time and only start doing this recently?

    voltage is 130, it would be considered a new installation as I replaced a tripplite 1012 with this 2012

    seems I need a 1000 Watt draw off of generator to stabilize voltage so inverter will switch to charge mode

    You could try slowing the generator down a little to reduce the light load voltage (eg, 125V).
