Connect inverter to house or chassis battery bank. AMPS X VOLTS = WATTAGE necessary. Usually a 1000W - 1200W inverter would work for that usage. Find out what Amperage your TV draws. Multiply this by 120. That equals the Wattage necessary. For the fridge, use the surge amperage for calculations. Add together all devices you will run at one time.
