I have 200 watts, and a 30amp solar controller. 2 RV deep cells and 1 High Rate Max solar battery. The controller shows they do about 10.5a/h in full light. Which is basically all day where I'm at.
I was having no problem using these inverters while hooking the inverter straight to the batteries. (Wired in parallel). I claimed they are full because I can watch movies on my Xbox, on my tv, and fully charge my phone and laptop batteries, along with using lights, and microwave, all in the same night. and also the control panel on the RV says full, it'll dip to 1/3 or less I'm assuming, but the next day it'll be full again.
