300w vs 500w inverter question
The television in our TT is a 32" Jenson that runs on 110v only. I have both 300w and 500w inverters, and both have proven to power the tv on battery power alone. Other than the obvious (the 50...

Ok, normally I'd talk about the advantages of a True Sine but.. The reason is this: There is a long list of things that MIGHT NOT WORK PROPERLY on MSW. This includes many TV's and Radios and audio/video gear.. HOWEVER.. In your case. you know it works, so we can skip all that and get to the meat of the issue.
300 or 500
Theory has it the 300 might be a bit more effiecent, HOWEVER you need to find out for sure.. here is how.
300 watts means about 30 amps draw at 12 volt.. USING a good DC ammeter (if the TV is drawing over 100 watts a clamp on should do) measure the current on the DC lead (i'd just measure the positive lead to the inverter) and take notes.
Switch to the 500 and take notes
Use the one with the lower current draw.
OR: IF you want a bit of power left over for the computer, Cell phone chargers etc... Total up your needs and if more than 280, Use the 5000 (I do not like loading to the max).
