f you just leave the inverter on, you are wasting about 1.5 amps continuously and will kill your batteries much more quickly.
It's a small draw.. but that wasn't the OP's question.
Your reply may not be relevant either.
Well, yes 1.5 Ahs is not much when you have 800Ahs of battery, or whatever you have in equivalent Whs.
Since the question was whether the OP
needs to turn the inverter switch off when on shore power, it appears the answer is YES. The reason is that there is more AC wattage available from shore power than the inverter alone and it would be easy to trip the inverter's overload limit which would result in the transfer switch activating AC at the outlets. This would cause unnecessary/unintended wear and tear on those circuits.
But, If the OP is off shore power and has 100 Ahs of 12V, then 1.5 A is 36Ah per day, or 36% of 100Ah. That leaves 14% left for something useful if the OP wishes to keep the daily capacity at 50% or above. In this case, leave the inverter switch off when the AC outlets are not needed.
