Unless "brewing" means running a 150A coffee maker - something that people on solar are normally trying to avoid - a single 12V is capable of energy usage described above, though it would have to work hard.
DirectTV receiver together with an efficient TV for 3-4 hours, plus pumps, LED lights and radio, will still leave enough juice in a single 12V battery in the morning to run a furnace for 1 or 2 hours non-stop (I mean no cycling) before SOC drops to 50%. BUT... If your TV is not very efficient, or if you also have DC circuits in LP fridge, or if your 12V battery didn't get to Float yesterday - then a single 12V won't cut it.
