Re: Using TV when off shore power
The breaker panel is for your 120VAC systems including Battery Charger, Outlets, Fridge, Stove, Water Heater, A/C. etc. 12VDC runs off your batteries and runs lights, stereo, pressure water pump (water faucets), guages, outdrive trim and trim tabs, bilge pumps, etc.
To run a TV (Typically 120V) you would need to run with shore power, a generator, or install an inverter to turn 12VDC to 120VAC.
