Hi dudeman! Welcome!

Well, I originally got two inverters because I had read that if you want to run, say, a 300 watt item, it'll be more efficient to run it on a smaller inverter than a larger one. So, I figured that I'd use my 600 watt inverter for smaller loads to save some battery juice.

But it turns out that that's not really true! I tried plugging something (can't remember what anymore) into my 600 watt inverter, and then I plugged it into my 2000 watt inverter. According to my battery monitor, the 2000 watt inverter was much more efficient! So now I just use my 2000 watt inverter for everything, and the 600 watt inverter is just a backup in case the 2000 watt inverter breaks.
