Running an LCD off an inverter

[JAS114]

I want to watch college football on the lake once in a while!

I have a 115 amp hour dual purpose deep cycle. It runs two fish finders (0.25A and 0.67A), a trolling motor (30A), and aerator (1.9A). I want to run a 15" LCD HDTV that draws 35 watts AC (0.30A). I have a 65W laptop inverter that will handle that no problem. I just want someone to verify my math here.

I think, if I plan to run the fish finders and aerator for 10 hours ([0.25A+0.67A+1.9A]*10hr=28.2AmpHrs), the trolling motor for 2 hours (2hr*30A=60AmpHrs), and the TV for 4 hours(0.3A*4hr=1.2AmpHrs), I'll have 115-28.2-60-1.2=25.6AmpHrs of reserve left.

I realize that I'm not accounting for the heat lost through the inverter, but basically, I just want to confirm that I'm right in my thinking that I'm gonna have enough juice to do this.

I have a seperate 24v system that just runs my bow mount, so I really won't even need to run the other trolling motor this long, but I want to be conservative so I don't run out of juice.

Thanks,
Josh

In that case you'll get a lot of fishing done, as there seems to be more commercials runing than there are actual shows showing these days, lol. Hope it works out for you. 8)

this will work with the digital tv signals...

You can run an LCD off of an inverter but it must be a "true sine wave" inverter.No square wave or modified wave inverters.Be aware that the cheaper inverters have misleading info about this.Anything other than a true sine wave can cause poor functionality and possible damage to the sensitive electronics and the back light inverter for the screen.

The inverter is intended for laptop use. Wouldn't a laptop be even more fragile than a LCD TV?

If it is intended for a lappy then it should be a true sine wave inverter.There should be no issues running an LCD screen.
