Is there a problem with oversizing an inverter

[New_Climber]

I am looking at getting an inverter to run my overhead lighting in my garage. In an effort to plan for future upgrades in panels and battery capacities....is there a problem with over sizing an inverter now.

At this time, I am looking to run only about 250watt of lights at the most. A more realistic amount would be about 150watt of CFL or LED lights. If I were to get a 600w or 1000w continuous inverter, would it give me issues only putting a load of 150w on it.

No you have to oversize True Sine Wave inverters to run non linear loads with low Power Factors. CFL and florescent lighting PF can be as low as .5. What that means is you have to have a 1000 watt inverter to run a max of 500 watt lighting

In some cases I believe a bigger inverter might have a higher current usage for the inverter it's self (regardless of load on it), so worth checking that out.
Otherwise, I've been fine sometimes just running a 20w charger from an 800w inverter.

There is some truth to that. Cheap inverters are very inefficient when operating at low power levels compared to there maximum output. This is another reason why battery systems should not be used unless no other means are available. Extremely inefficient and costly. Non Linear loads and low power factor do not play well with inverters.
