i think tis wired that way, if any thing was wrong, there will be outlets with NO power any time
if you have any like that, that do not work from shore or generator
turn off all power and then look for loose wires
1000w will power a DRIP coffee maker or a 600w MW , (BUT not a Kuerig or espresso machine)
our inverter circuit is 'most' not all of only the drivers side
(2) duplex in the bedroom, (1) in the kitchen and the front entertainment outlet
which was also the OEM backup monitor (the overhead TV was the BU monitor) (since replaced) real neck breaker
nothing on the passenger side was on the inverter
i ran a dedicated circuit which powers the residential fridge i installed
