The 300 watt kit isn't enough for 4 - 6 volt GC batteries. It is perfect for two GC batteries. If you plan on the 4-6 volt GC's you will need at least 400 watt and a MPPT controller and even that will be marginal for longest battery life.
The inverter only has an efficiency of 83 to 85 %. If you have to have a TV look for something in 12 volt with LED screen.
As a starting point 100 watts of solar per 100 AH of battery is a very minimum.
You don't need an MPPT for 400 watts. While nice to have not a necessity.
