    All power systems failed at the same time

    Complete system shut down except tv and lights on microwave. Refrigerator, generator, control panel, lights etc everything else off while plugged into shore power. Gas would not switch over to power the refrigerator.
    No power to Onan generator so it canít start. Solar would not work. Shore power would not work. We even brought over our sonís generator to rule out that being a problem and nothing. Approximately 8 hours later it turned back on over night. Generator start switch light is still not on.
    Solar system transfer switch (contacts) is possibly bad. Though not sure how that could affect generator and shore power? The shut off for no reason when almost everything but a few lights were shut off. ACs were not running at that time.

    Sounds like a 12DC power failure. AC power to TV and Microwave was still available. But no DC power to the lights and refer controls.

    Can you please provide more info on your trailer? Model / Year / etc.
    Where are you located?
    The more details the better.

    Did you do any electrical troubleshooting with a volt meter? Results?

    My first guess is the converter is not supplying the 12VDC power needed for the lights and refrigerator controls to work. The battery goes dead without the converter to recharge it. You mention solar so it is possible the solar will put some charge into the batteries during the day but many solar systems don’t have enough wattage to run everything and charge the batteries.

    Concur with @DougW9876. Sounds like the converter.
    - Is the converter circuit breaker on. Recommend shutting it off then back on again.
    - What is the battery voltage?
    - Do you have 14ish volts coming out of the converter?
    - Check the converter DC fuses. Pull each fuse and do a visual check. Can also check continuity with the meter.
    - Check for blown fuses in your DC distribution panel.
    - For solar, check voltage into and out of the charge controller.
    - Check for any loose DC cable connections.

    Let us know what you find. Remember...RVing is an adventure!

    Check you battery disconnect switch while your at it, Red key in turned to ON and key cant be removed. Key must be on for batterys to get power form converter and probably solar too.
