    Company just got me onto a brand new '24 Cascadia, I'm the first driver. I have nothing plugged into the outlets first of all. But when I try and turn the inverter on it spits out this E03 code and beeps incessantly until I turn it off.

    From what I can tell it's a code that comes up when you have too much stuff plugged in but as I've said I have nothing plugged into the outlets, and never have bc it's been doing this since I got it, any ideas how to fix it so I can use my outlets?

    Do you have a manual for it?
    If not you’ll need to google the brand and model number and see if there’s a manual reset procedure.
    You can power it down,then take the ground off the batteries and see if that will reset it.
