Just so you know, lets say the TV and inverter consume 150wh, then for every hour you watch TV you're going to draw down the batteries 12.5ah. Assuming you have 225ah of battery, that's 9 hours of TV watching before you need to recharge (discharge no more than 50%). In reality it will be less because you'll also have to consider the parasitic load as well as lights, water pump etc.
