What you are doing is possibly dangerous and if you get lucky and don't hurt yourself, you will damage the components you have. I've never seen the device you have but it took me all of 15 seconds to find it on the web and to read enough of the instructions to know that this controller has a maximum open circuit input voltage of 55 volts. If you put 70 volts on it, you will mostly likely damage it. It can then be configured to charge a 12 volt, 24 volts, or 48 volt bank of batteries.

Uniform regulations in country require that you wear long sleeves and long pants and a hat any time you are in combat uniform. They also drink a LOT of water. Living quarters on larger bases are air-conditioned, so you can come inside and cool off between missions. You spend two weeks in Kuwait before you get to your combat location. Main purpose of that is so troops have a chance to acclimate. Sunglasses and sunscreen are a good idea.

If the TV requires 300 watts, a guess, then if you want to run it for 4 hours, that is 300*4 = 1200 watt hours. You should check around for a low power LCD TV, you may be able to lower that number. A large marine battery will store about 1200 watt hours, so a fully charged one will just run your TV for those 4 hours. At 12 volts, after inverter losses, that will be 360 watts, or 30 amps. That will take a large solar array. If you need to operate this TV over a long time period, you will need a gasoline generator. bottom line, find out how much power you need, and for how long and I can discuss in more detail. .

On all the overnight flights I've taken --- the lights are normally dimmed really low to allow passengers to get some shut-eye. You do have control of the overhead lamp but don't know whether there's enough energy there to keep you going for too long!! It should be okay on daytime flights though. There's plenty of light in the cabin from the windows, which are typically left open (some at least!). A concern would be whether it an over-night flight or not.
