    If it's a 2012 and still gas the original batteries, I would say it's time to change them.
    Besides that, it's more likely the alternator has crapped out.
    Easy to change yourself.

    Disconnect your batteries and load test them individually. you probably have at least one bad battery.

    I just replaced all my batteries - have an APU - often, especially after a washing or heavy rain, my low power accessory shutoff kicks off the accessory power when there is still plenty of power - and the voltage I read on the voltage meter does not match what the Inverter is seeing straight from the batteries. Sometimes it will not reset even when the APU senses low power and kicks on to charge the batteries.

    Weird-
