Another inverter question!
If you have a 1,000w inverter running an LCD tv, and a 2000w inverter running an identical LCD tv. Does the 2000w inverter use more battery power? You see, I bought a 2000w inverter to run my micr...

So now I have a 2000w PSW inverter powering my LCD tv. Overkill much???
About 20 times overkill.

I'm just wondering if I should try and barter for a smaller inverter because the 2K watt may be wasting more of my battery than a 1,000 watt would.
If you want to run generator less often - yes.
More rated power almost always means more idle current. This idle current in 2000W inverter will cost you a lot of amp-hours in 24-hr period. You need to make sure that you turn it off when not in use. But sometimes you forget to turn it off or don't want to, because your DW says she'll be doing her hair "soon", or some other reason. Whether idle current adds 100% to the load current or not, it does consume energy when there is no load.
OTH, when there is a load, then efficiency of inverter comes into play, but this loss is more difficult to estimate because it depends on the load and you never know for sure how many hours and at what load you are using it.
If you can barter it for inverter that has both lower idle current and better efficiency, this would be the best solution.
