You probably have an inverter transfer switch which bypasses shore or generator power around inverter, so the inverter would fall back to idling under no load even if left on.
I'd get an electrical schematic (if you don't have one already) to confirm details. It's good to know specifics of what you are working with.
Assuming you have a built-in inverter transfer switch, I'd call the inverter manufacturer and ask them about life expectancy if left on. They should know best.
Inverters do use significant power even when under no load, so unless you were using it, it wouldn't make sense to leave it on unless you had shore or generator power. When you have shore or generator power it wouldn't matter as much leaving the inverter running under no load because the few watts of power it uses from your batteries would be made up by the converter.
