Why does the inverter run on my 2020 classic 33? Itís under my bed and the fan runs unless I kill it at the control panel.. Iím on shore power 50 amp. What does it do? Can I or should I disable it??

The inverters are also sold for use as uninterruptible power so they are designed as pass through for utility power with the inverter in standby ready to switch in less than 2 milliseconds. generally, you don't need this in an RV. It draws about 2 amps from the battery on standby, so I suggest turning it off except when in active use. I keep mine off. It draws nearly 4 amps when on and active with no connected load. It draws 0.02 amps when off

Edit: the inverter provides 120V power for the entertainment system and (very) small appliances when you don't have shore power.

Are you using cinema mode by any chance? I thought I recalled that this was designed into the trailer to turn that sucker on when on cinema mode regardless of shore power or not.
