Inverter problems

I have a 2012 Itasca Suncruiser 37F. The remote panel to the inverter quit working. I begin checking and noticed that when the unit is not on shore power the inverter does not operate. I plugged in my cell phone on the outlet located on the inverter itself and nothing.
I made sure the battery disconnect was not turned off.
The batteries are charged and are around 12 volts.
The inverter is a Xantrex Pro XM1000
Checked all fuses.
The radios in the coach work but no TV's.
1. How long should the inverter last? I would think 4 years at least.
2. Any ideas?
Thank you

    charging should be over 13v
    it should float fully charged batteries at 13.2v
    high charge should be 14.4

    most inverters shut off around 11~11.5 under load, then have to be reset

    you got a problem, try a disconnect reset, see if it charges at a higher voltage
    wait until the batteries are charged, then try the invert function
    invert works when shore power is disconnected

    no power pass thru, when connected, could indicate a burned out pass thru relay or control circuit failure

    Could be just the remote has failed. Try a reboot by disconnecting all 120v and 12v power for a bit then reconnect. I would test with a 60w incandescent lamp or a voltmeter over the phone charger. Voltage normally reads low on most meters for MSW.

    Consider this an opportunity to move up to sine wave power.

    around 12 volts? I think 12 volts is 50%. its possible maybe it has shut down because of being that low. that would also indicate the charging portion is not working
